Node.js

PptxGenJS NPM Homepage

npm install pptxgenjs

var pptx = require("pptxgenjs");

Desktop: Compatible with Electron applications!

Presentations: Usage and Options

PptxGenJS PowerPoint presentations are created via JavaScript by following 4 basic steps:

Create a new Presentation
Add a Slide
Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
Save the Presentation

var pptx = new PptxGenJS();
var slide = pptx.addNewSlide();
slide.addText('Hello World!', { x:1.5, y:1.5, font_size:18, color:'363636' });
pptx.save('Sample Presentation');

That's really all there is to it!

Creating a Presentation

A Presentation is a single .pptx file. When creating more than one Presentation, declare the pptx again to start with a new, empty Presentation.

Client Browser:

var pptx = new PptxGenJS();

Node.js:

var pptx = require("pptxgenjs");

Presentation Properties

There are several optional properties that can be set:

pptx.setAuthor('Brent Ely');
pptx.setCompany('S.T.A.R. Laboratories');
pptx.setRevision('15');
pptx.setSubject('Annual Report');
pptx.setTitle('PptxGenJS Sample Presentation');

Presentation Layouts

Setting the Layout (applies to all Slides in the Presentation):

pptx.setLayout('LAYOUT_WIDE');

Presentation Layout Options

Layout Name	Default	Layout Slide Size
`LAYOUT_16x9`	Yes	10 x 5.625 inches
`LAYOUT_16x10`	No	10 x 6.25 inches
`LAYOUT_4x3`	No	10 x 7.5 inches
`LAYOUT_WIDE`	No	13.3 x 7.5 inches
`LAYOUT_USER`	No	user defined - see below (inches)

Custom user defined Layout sizes are supported - just supply a name and the size in inches.

Defining a new Layout using an object will also set this new size as the current Presentation Layout

// Defines and sets this new layout for the Presentation
pptx.setLayout({ name:'A3', width:16.5, height:11.7 });

Presentation Text Direction

Right-to-Left (RTL) text is supported. Simply set the RTL mode at the Presentation-level.

pptx.setRTL(true);

Adding a Slide

Syntax:

var slide = pptx.addNewSlide();

Slide Formatting

slide.back  = 'F1F1F1';
slide.color = '696969';

Slide Formatting Options

Option	Type	Unit	Default	Description	Possible Values
`bkgd`	string		`FFFFFF`	background color	hex color code or scheme color constant.
`color`	string		`000000`	default text color	hex color code or scheme color constant.

Applying Master Slides / Branding

// Create a new Slide that will inherit properties from a pre-defined master page (margins, logos, text, background, etc.)
var slide1 = pptx.addNewSlide( pptx.masters.TITLE_SLIDE );

// The background color can be overridden on a per-slide basis:
var slide2 = pptx.addNewSlide( pptx.masters.TITLE_SLIDE, {bkgd:'FFFCCC'} );

Adding Slide Numbers

slide.slideNumber({ x:1.0, y:'90%' });
// Slide Numbers can be styled:
slide.slideNumber({ x:1.0, y:'90%', fontFace:'Courier', fontSize:32, color:'CF0101' });

Slide Number Options

Option	Type	Unit	Default	Description	Possible Values
`x`	number	inches	`0.3`	horizontal location	0-n OR 'n%'. (Ex: `{x:'10%'}` places number 10% from left edge)
`y`	number	inches	`90%`	vertical location	0-n OR 'n%'. (Ex: `{y:'90%'}` places number 90% down the Slide)
`color`	string			text color	hex color code or scheme color constant. Ex: `{color:'0088CC'}`
`fontFace`	string			font face	any available font. Ex: `{fontFace:Arial}`
`fontSize`	number	points		font size	8-256. Ex: `{fontSize:12}`

Slide Return Value

The Slide object returns a reference to itself, so calls can be chained.

Example:

slide
.addImage({ path:'images/logo1.png', x:1, y:2, w:3, h:3 })
.addImage({ path:'images/logo2.jpg', x:5, y:3, w:3, h:3 })
.addImage({ path:'images/logo3.png', x:9, y:4, w:3, h:3 });

Saving a Presentation

Presentations require nothing more than passing a filename to save(). Node.js users have more options available examples of which can be found below.

Client Browser

Simply provide a filename

pptx.save('Demo-Media');

Node.js

Node can accept a callback function that will return the filename once the save is complete
Node can also be used to stream a powerpoint file - simply pass a filename that begins with "http"
Output type can be specified by passing an optional JSZip output type

// Example A: File will be saved to the local working directory (`__dirname`)
pptx.save('Node_Demo');

// Example B: Inline callback function
pptx.save('Node_Demo', function(filename){ console.log('Created: '+filename); });

// Example C: Predefined callback function
pptx.save('Node_Demo', saveCallback);

// Example D: Use a filename of "http" or "https" to receive the powerpoint binary data in your callback
// (Used for streaming the presentation file via http.  See the `nodejs-demo.js` file for a working example.)
pptx.save('http', streamCallback);

// Example E: Save using various JSZip output types: ['arraybuffer', 'base64', 'binarystring', 'blob', 'nodebuffer', 'uint8array']
pptx.save('jszip', saveCallback, 'base64');

Saving Multiple Presentations

Client-Side:

In order to generate a new, unique Presentation just create a new instance of the library then add objects and save as normal.

var pptx = require("pptxgenjs");
pptx.addNewSlide().addText('Presentation 1', {x:1, y:1});
pptx.save('PptxGenJS-Presentation-1');

// Create a new instance ("Reset")
pptx = require("pptxgenjs");
pptx.addNewSlide().addText('Presentation 2', {x:1, y:1});
pptx.save('PptxGenJS-Presentation-2');

Node.js:

Multiple presentations are a bit more complicated in Node - see Issue #83

Presentations: Adding Objects

Objects on the Slide are ordered from back-to-front based upon the order they were added.

For example, if you add an Image, then a Shape, then a Textbox: the Textbox will be in front of the Shape, which is in front of the Image.

Adding Charts

// Syntax
slide.addChart({TYPE}, {DATA}, {OPTIONS});

Chart Types

Chart type can be any one of pptx.charts
Currently: pptx.charts.AREA, pptx.charts.BAR, pptx.charts.BUBBLE, pptx.charts.LINE, pptx.charts.SCATTER, pptx.charts.PIE, pptx.charts.DOUGHNUT

Multi-Type Charts

Chart types can be any one of pptx.charts, although pptx.charts.AREA, pptx.charts.BAR, and pptx.charts.LINE will give the best results.
There should be at least two chart-types. There should always be two value axes and category axes.
Multi Charts have a different function signature than standard. There are two parameters:
chartTypes: Array of objects, each with type, data, and options objects.
options: Standard options as used with single charts. Can include axes options.
Columns makes the most sense in general. Line charts cannot be rotated to match up with horizontal bars (a PowerPoint limitation).
Can optionally have a secondary value axis.
If there is secondary value axis, a secondary category axis is required in order to render, but currently always uses the primary labels. It is recommended to use catAxisHidden: true on the secondary category axis.
Standard options are used, and the chart-type-options are mixed in to each.

// Syntax
slide.addChart({MULTI_TYPES_AND_DATA}, {OPTIONS_AND_AXES});

Adding Tables

Syntax:

slide.addTable( [rows] );
slide.addTable( [rows], {any Layout/Formatting OPTIONS} );

Table Layout Options

Option	Type	Unit	Default	Description	Possible Values
`x`	number	inches	`1.0`	horizontal location	0-n OR 'n%'. (Ex: `{x:'50%'}` will place object in the middle of the Slide)
`y`	number	inches	`1.0`	vertical location	0-n OR 'n%'.
`w`	number	inches		width	0-n OR 'n%'. (Ex: `{w:'50%'}` will make object 50% width of the Slide)
`h`	number	inches		height	0-n OR 'n%'.
`colW`	integer	inches		width for every column	Ex: Width for every column in table (uniform) `2.0`
`colW`	array	inches		column widths in order	Ex: Width for each of 5 columns `[1.0, 2.0, 2.5, 1.5, 1.0]`
`rowH`	integer	inches		height for every row	Ex: Height for every row in table (uniform) `2.0`
`rowH`	array	inches		row heights in order	Ex: Height for each of 5 rows `[1.0, 2.0, 2.5, 1.5, 1.0]`

Table Auto-Paging Options

Option	Type	Default	Description	Possible Values
`autoPage`	boolean	`true`	auto-page table	`true` or `false`. Ex: `{autoPage:false}`
`lineWeight`	float	0	line weight value	-1.0 to 1.0. Ex: `{lineWeight:0.5}`
`newPageStartY`	object		starting `y` value for tables on new Slides	0-n OR 'n%'. Ex:`{newPageStartY:0.5}`

Table Auto-Paging Notes

Tables will auto-page by default and the table on new Slides will use the current Slide's top margin value as the starting point for y. Tables will retain their existing x, w, and colW values as they are continued onto subsequent Slides.

autoPage: allows the auto-paging functionality (as table rows overflow the Slide, new Slides will be added) to be disabled.
lineWeight: adjusts the calculated height of lines. If too much empty space is left under each table, then increase lineWeight value. Conversely, if the tables are overflowing the bottom of the Slides, then reduce the lineWeight value. Also helpful when using some fonts that do not have the usual golden ratio.
newPageStartY: provides the ability to specify where new tables will be placed on new Slides. For example, you may place a table halfway down a Slide, but you wouldn't that to be the starting location for subsequent tables. Use this option to ensure there is no wasted space and to guarantee a professional look.

Table Formatting Options

Option	Type	Unit	Default	Description	Possible Values
`align`	string		`left`	alignment	`left` or `center` or `right` (or `l` `c` `r`)
`bold`	boolean		`false`	bold text	`true` or `false`
`border`	object			cell border	object with `pt` and `color` values. Ex: `{pt:'1', color:'f1f1f1'}`
`border`	array			cell border	array of objects with `pt` and `color` values in TRBL order.
`color`	string			text color	hex color code or scheme color constant. Ex: `{color:'0088CC'}`
`colspan`	integer			column span	2-n. Ex: `{colspan:2}`
`fill`	string			fill/bkgd color	hex color code or scheme color constant. Ex: `{color:'0088CC'}`
`font_face`	string			font face	Ex: `{font_face:'Arial'}`
`font_size`	number	points		font size	1-256. Ex: `{font_size:12}`
`italic`	boolean		`false`	italic text	`true` or `false`
`margin`	number	points		margin	0-99 (ProTip: use the same value from CSS `padding`)
`margin`	array	points		margin	array of integer values in TRBL order. Ex: `margin:[5,10,5,10]`

`underline`	boolean		`false`	underline text	`true` or `false`
`valign`	string			vertical alignment	`top` or `middle` or `bottom` (or `t` `m` `b`)

Table Formatting Notes

Formatting Options passed to slide.addTable() apply to every cell in the table
You can selectively override formatting at a cell-level providing any Formatting Option in the cell options

Table Cell Formatting

Table cells can be either a plain text string or an object with text and options properties
When using an object, any of the formatting options above can be passed in options and will apply to that cell only
Cell borders can be removed (aka: borderless table) by passing a 'none' (Ex: border:'none')

Bullets and word-level formatting are supported inside table cells. Passing an array of objects with text/options values as the text value allows fine-grained control over the text inside cells.

Available formatting options are here: Text Options
See below for examples or view the examples/pptxgenjs-demo.html page for lots more

Table Cell Formatting Examples

// TABLE 1: Cell-level Formatting
var rows = [];
// Row One: cells will be formatted according to any options provided to `addTable()`

// Row Two: set/override formatting for each cell
rows.push([
    { text:'1st', options:{color:'ff0000'} },
    { text:'2nd', options:{color:'00ff00'} },
    { text:'3rd', options:{color:'0000ff'} }
]);
slide.addTable( rows, { x:0.5, y:1.0, w:9.0, color:'363636' } );

// TABLE 2: Using word-level formatting inside cells
// NOTE: An array of text/options objects provides fine-grained control over formatting
var arrObjText = [
    { text:'Red ',   options:{color:'FF0000'} },
    { text:'Green ', options:{color:'00FF00'} },
    { text:'Blue',   options:{color:'0000FF'} }
];
// EX A: Pass an array of text objects to `addText()`
slide.addText( arrObjText, { x:0.5, y:2.75, w:9, h:2, margin:0.1, fill:'232323' } );

// EX B: Pass the same objects as a cell's `text` value
var arrTabRows = [
    [
        { text:'Cell 1 A',  options:{font_face:'Arial'  } },
        { text:'Cell 1 B',  options:{font_face:'Courier'} },
        { text: arrObjText, options:{fill:'232323'}       }
    ]

Adding Images

Syntax:

slide.addImage({OPTIONS});

Animated GIFs can be included in Presentations in one of two ways:

Using Node.js: use either data or path options (Node can encode any image into base64)
Client Browsers: pre-encode the gif and add it using the data option (encoding images into GIFs is beyond any current browser)

Image Options

Option	Type	Unit	Default	Description	Possible Values
`x`	number	inches	`1.0`	horizontal location	0-n
`y`	number	inches	`1.0`	vertical location	0-n
`w`	number	inches	`1.0`	width	0-n
`h`	number	inches	`1.0`	height	0-n
`data`	string			image data (base64)	base64-encoded image string. (either `data` or `path` is required)
`hyperlink`	string			add hyperlink	object with `url` and optionally `tooltip`. Ex: `{ hyperlink:{url:'https://github.com'} }`
`path`	string			image path	Same as used in an (img src="") tag. (either `data` or `path` is required)
`sizing`	object			transforms image	See Image Sizing

NOTES

SVG images are not currently supported in PowerPoint or PowerPoint Online (even when encoded into base64). PptxGenJS does properly encode and include SVG images, so they will begin showing once Microsoft adds support for this image type.
Using path to add remote images (images from a different server) is not currently supported.

Deprecation Warning Old positional parameters (e.g.: slide.addImage('images/chart.png', 1, 1, 6, 3)) are now deprecated as of 1.1.0

Image Examples

var pptx = new PptxGenJS();
var slide = pptx.addNewSlide();

// Image by path
slide.addImage({ path:'images/chart_world_peace_near.png', x:1.0, y:1.0, w:8.0, h:4.0 });
// Image by data (base64-encoding)
slide.addImage({ data:'image/png;base64,iVtDafDrBF[...]=', x:3.0, y:5.0, w:6.0, h:3.0 });

// NOTE: Slide API calls return the same slide, so you can chain calls:
slide.addImage({ path:'images/cc_license_comp_chart.png', x:6.6, y:0.75, w:6.30, h:3.70 })
     .addImage({ path:'images/cc_logo.jpg',               x:0.5, y:3.50, w:5.00, h:3.70 })
     .addImage({ path:'images/cc_symbols_trans.png',      x:6.6, y:4.80, w:6.30, h:2.30 });

// Image with Hyperlink
slide.addImage({
  x:1.0, y:1.0, w:8.0, h:4.0,
  hyperlink:{ url:'https://github.com/gitbrent/pptxgenjs', tooltip:'Visit Homepage' },
  path:'images/chart_world_peace_near.png',
});

pptx.save('Demo-Images');

Image Sizing

The sizing option provides cropping and scaling an image to a specified area. The property expects an object with the following structure:

Property	Type	Unit	Default	Description	Possible Values
`type`	string			sizing algorithm	`'crop'`, `'contain'` or `'cover'`
`w`	number	inches	`w` of the image	area width	0-n
`h`	number	inches	`h` of the image	area height	0-n
`x`	number	inches	`0`	area horizontal position related to the image	0-n (effective for `crop` only)
`y`	number	inches	`0`	area vertical position related to the image	0-n (effective for `crop` only)

Particular type values behave as follows:

contain works as CSS property background-size — shrinks the image (ratio preserved) to the area given by w and h so that the image is completely visible. If the area's ratio differs from the image ratio, an empty space will surround the image.
cover works as CSS property background-size — shrinks the image (ratio preserved) to the area given by w and h so that the area is completely filled. If the area's ratio differs from the image ratio, the image is centered to the area and cropped.
crop cuts off a part specified by image-related coordinates x, y and size w, h.

NOTES:

If you specify an area size larger than the image for the contain and cover type, then the image will be stretched, not shrunken.
In case of the crop option, if the specified area reaches out of the image, then the covered empty space will be a part of the image.
When the sizing property is used, its w and h values represent the effective image size. For example, in the following snippet, width and height of the image will both equal to 2 inches and its top-left corner will be located at [1 inch, 1 inch]:

slide.addImage({
  path: '...',
  w: 4,
  h: 3,
  x: 1,
  y: 1,
  sizing: {
    type: 'contain',
    w: 2,
    h: 2
  }
});

Adding Media (Audio/Video/YouTube)

Syntax:

slide.addMedia({OPTIONS});

Both Video (mpg, mov, mp4, m4v, etc.) and Audio (mp3, wav, etc.) are supported (list of supported formats)

Using Node.js: use either data or path options (Node can encode any media into base64)
Client Browsers: pre-encode the media and add it using the data option (encoding video/audio is beyond any current browser)

Online video (YouTube embeds, etc.) is supported in both client browser and in Node.js

Media Options

Option	Type	Unit	Default	Description	Possible Values
`x`	number	inches	`1.0`	horizontal location	0-n
`y`	number	inches	`1.0`	vertical location	0-n
`w`	number	inches	`1.0`	width	0-n
`h`	number	inches	`1.0`	height	0-n
`data`	string			media data (base64)	base64-encoded string
`path`	string			media path	relative path to media file
`link`	string			online url/link	link to online video. Ex: `link:'https://www.youtube.com/embed/blahBlah'`
`type`	string			media type	media type: `audio` or `video` (reqs: `data` or `path`) or `online` (reqs:`link`)

Media Examples

var pptx = new PptxGenJS();
var slide = pptx.addNewSlide();

// Media by path (Node.js only)
slide.addMedia({ type:'audio', path:'../media/sample.mp3', x:1.0, y:1.0, w:3.0, h:0.5 });
// Media by data (client browser or Node.js)
slide.addMedia({ type:'audio', data:'audio/mp3;base64,iVtDafDrBF[...]=', x:3.0, y:1.0, w:6.0, h:3.0 });
// Online by link (client browser or Node.js)
slide.addMedia({ type:'online', link:'https://www.youtube.com/embed/Dph6ynRVyUc', x:1.0, y:4.0, w:8.0, h:4.5 });

pptx.save('Demo-Media');

Master Slides and Corporate Branding

Slide Masters

Generating sample slides like those shown above is great for demonstrating library features, but the reality is most of us will be required to produce presentations that have a certain design or corporate branding.

PptxGenJS allows you to define Slide Master Layouts via objects that can then be used to provide branding functionality.

Slide Masters are created by calling the defineSlideMaster() method along with an options object (same style used in Slides). Once defined, you can pass the Master title to addNewSlide() and that Slide will use the Layout previously defined. See the demo under /examples for several working examples.

The defined Masters become first-class Layouts in the exported PowerPoint presentation and can be changed via View > Slide Master and will affect the Slides created using that layout.

Slide Master Object Options

Option	Type	Unit	Default	Description	Possible Values
`bkgd`	string		`ffffff`	color	hex color code or scheme color constant. Ex: `{ bkgd:'0088CC' }`
`bkgd`	object			image	object with path OR data. Ex: `{path:'img/bkgd.png'}` OR `{data:'image/png;base64,iVBORwTwB[...]='}`
`slideNumber`	object			Show slide numbers	ex: `{ x:1.0, y:'50%' }` `x` and `y` can be either inches or percent
`margin`	number	inches	`1.0`	Slide margins	0.0 through Slide.width
`margin`	array			Slide margins	array of numbers in TRBL order. Ex: `[0.5, 0.75, 0.5, 0.75]`
`objects`	array			Objects for Slide	object with type and options. Type:`chart`,`image`,`line`,`rect` or `text`. Example
`title`	string			Layout title/name	some title

TIP: Pre-encode your images (base64) and add the string as the optional data key/val (see bkgd above)

Slide Master Examples

var pptx = new PptxGenJS();
pptx.setLayout('LAYOUT_WIDE');

pptx.defineSlideMaster({
  title: 'MASTER_SLIDE',
  bkgd:  'FFFFFF',
  objects: [
    { 'line':  { x: 3.5, y:1.00, w:6.00, line:'0088CC', line_size:5 } },
    { 'rect':  { x: 0.0, y:5.30, w:'100%', h:0.75, fill:'F1F1F1' } },
    { 'text':  { text:'Status Report', options:{ x:3.0, y:5.30, w:5.5, h:0.75 } } },
    { 'image': { x:11.3, y:6.40, w:1.67, h:0.75, path:'images/logo.png' } }
  ],
  slideNumber: { x:0.3, y:'90%' }
});

var slide = pptx.addNewSlide('MASTER_SLIDE');
slide.addText('How To Create PowerPoint Presentations with JavaScript', { x:0.5, y:0.7, font_size:18 });

pptx.save();

Table-to-Slides Feature

Syntax:

slide.addSlidesForTable(htmlElementID);
slide.addSlidesForTable(htmlElementID, {OPTIONS});

Any variety of HTML tables can be turned into a series of slides (auto-paging) by providing the table's ID.

Reproduces an HTML table - background colors, borders, fonts, padding, etc.
Slide margins are based on either the Master Slide provided or options

NOTE: Nested tables are not supported in PowerPoint, so only the string contents of a single level deep table cell will be reproduced

Table-to-Slides Options

Option	Type	Unit	Description	Possible Values
`x`	number	inches	horizontal location	0-256. Table will be placed here on each Slide
`y`	number	inches	vertical location	0-256. Table will be placed here on each Slide
`w`	number	inches	width	0-256. Default is (100% - Slide margins)
`h`	number	inches	height	0-256. Default is (100% - Slide margins)
`master`	string		master slide name	Any pre-defined Master Slide. Ex: `{ master:pptx.masters.TITLE_SLIDE }`
`addHeaderToEach`	boolean		add table headers to each slide	Ex: `addHeaderToEach:true`
`addImage`	string		add an image to each slide	Ex: `{ addImage:{ path:"images/logo.png", x:10, y:0.5, w:1.2, h:0.75 } }`
`addShape`	string		add a shape to each slide	Use the established syntax.
`addTable`	string		add a table to each slide	Use the established syntax.
`addText`	string		add text to each slide	Use the established syntax.

Table-to-Slides HTML Options

A minimum column width can be specified by adding a data-pptx-min-width attribute to any given <th> tag.

Example:

<table id="tabAutoPaging" class="tabCool">
  <thead>
    <tr>
      <th data-pptx-min-width="0.6" style="width: 5%">Row</th>
      <th data-pptx-min-width="0.8" style="width:10%">Last Name</th>
      <th data-pptx-min-width="0.8" style="width:10%">First Name</th>
      <th                           style="width:75%">Description</th>
    </tr>
  </thead>
  <tbody></tbody>
</table>

Table-to-Slides Notes

Default x, y and margin value is 0.5 inches, the table will take up all remaining space by default (h:100%, w:100%)
Your Master Slides should already have defined margins, so a Master Slide name is the only option you'll need most of the time

Table-to-Slides Examples

// Pass table element ID to addSlidesForTable function to produce 1-N slides
pptx.addSlidesForTable( 'myHtmlTableID' );

// Optionally, include a Master Slide name for pre-defined margins, background, logo, etc.
pptx.addSlidesForTable( 'myHtmlTableID', { master:pptx.masters.MASTER_SLIDE } );

// Optionally, add images/shapes/text/tables to each Slide
pptx.addSlidesForTable( 'myHtmlTableID', { addText:{ text:"Dynamic Title", options:{x:1, y:0.5, color:'0088CC'} } } );
pptx.addSlidesForTable( 'myHtmlTableID', { addImage:{ path:"images/logo.png", x:10, y:0.5, w:1.2, h:0.75 } } );

Creative Solutions

Design a Master Slide that already contains: slide layout, margins, logos, etc., then you can produce professional looking Presentations with a single line of code which can be embedded into a link or a button:

Add a button to a webpage that will create a Presentation using whatever table data is present:

<input type="button" value="Export to PPTX"
 onclick="{ var pptx = new PptxGenJS(); pptx.addSlidesForTable('tableId',{ master:pptx.masters.MASTER_SLIDE }); pptx.save(); }">

SharePoint Integration

Placing a button like this into a WebPart is a great way to add "Export to PowerPoint" functionality to SharePoint. (You'd also need to add the 4 <script> includes in the same or another WebPart)

Full PowerPoint Shape Library

If you are planning on creating Shapes (basically anything other than Text, Tables or Rectangles), then you'll want to include the pptxgen.shapes.js library.

The shapes file contains a complete PowerPoint Shape object array thanks to the officegen project.

<script lang="javascript" src="PptxGenJS/dist/pptxgen.shapes.js"></script>

Scheme Colors

Scheme color is a variable that changes its value whenever another scheme palette is selected. Using scheme colors, design consistency can be easily preserved throughout the presentation and viewers can change color theme without any text/background contrast issues.

To use a scheme color, set a color constant as a property value:

slide.addText('Hello',  { color: pptx.colors.TEXT1 });

The colors file contains a complete PowerPoint palette definition.

<script lang="javascript" src="PptxGenJS/dist/pptxgen.colors.js"></script>

Performance Considerations

It takes CPU time to read and encode images! The more images you include and the larger they are, the more time will be consumed. The time needed to read/encode images can be completely eliminated by pre-encoding any images (see below).

Pre-Encode Large Images

Pre-encode images into a base64 string (eg: 'image/png;base64,iVBORw[...]=') for use as the data option value. This will both reduce dependencies (who needs another image asset to keep track of?) and provide a performance boost (no time will need to be consumed reading and encoding the image).

Integration with Other Libraries

Integration with Angular

Some modifications can be made to the library to accommodate building with Angular.

See Issue #220 for more information

Integration with Webpack/Typescript

Add this to your webpack config to avoid a module resolution error: node: { fs: "empty" }

See Issue #72 for more information

Issues / Suggestions

Please file issues or suggestions on the issues page on github, or even better, submit a pull request. Feedback is always welcome!

When reporting issues, please include a code snippet or a link demonstrating the problem. Here is a small jsFiddle that is already configured and uses the latest PptxGenJS code.

Need Help?

Sometimes implementing a new library can be a difficult task and the slightest mistake will keep something from working. We've all been there!

If you are having issues getting a presentation to generate, check out the demos in the examples directory. There are demos for both Nodejs and client-browsers that contain working examples of every available library feature.

Use a pre-configured jsFiddle to test with: PptxGenJS Fiddle
Use Ask Question on StackOverflow - be sure to tag it with "PptxGenJS"

Development Roadmap

Version 2.0 will be released in 2018 and will break Node (and probably other library) integration as the PptxGenJS export is updated to a constructor.

Unimplemented Features

The PptxGenJS library is not designed to replicate all the functionality of PowerPoint, meaning several features are not on the development roadmap.

These include:

Animations
Cross-Slide Links
Importing Existing Presentations and/or Templates
Outlines
SmartArt
