Frontend Mentor - Kanban task management web app

Welcome! 👋

Thanks for purchasing this premium Frontend Mentor coding challenge.

Frontend Mentor challenges help you improve your coding skills by building realistic projects. These premium challenges are perfect portfolio pieces, so please feel free to use what you create in your portfolio to show others.

To do this challenge, you need a very strong understanding of HTML, CSS, and JavaScript.

The challenge

Your challenge is to build out this task management app and get it looking as close to the design as possible.

You can use any tools you like to help you complete the challenge. So, if you've got something you'd like to practice, feel free to give it a go.

We provide the data in a local data.json file, so use that to populate the content on the first load. If you want to take it up a notch, feel free to build this as a full-stack application!

Your users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Create, read, update, and delete boards and tasks
• Receive form validations when trying to create/edit boards and tasks
• Mark subtasks as complete and move tasks between columns
• Hide/show the board sidebar
• Toggle the theme between light/dark modes
• Bonus: Allow users to drag and drop tasks to change their status and re-order them in a column
• Bonus: Keep track of any changes, even after refreshing the browser (localStorage could be used for this if you're not building out a full-stack app)
• Bonus: Build this project as a full-stack application

Expected Behaviour

• Boards
  • Clicking different boards in the sidebar will change to the selected board.
  • Clicking "Create New Board" in the sidebar opens the "Add New Board" modal.
  • Clicking in the dropdown menu "Edit Board" opens up the "Edit Board" modal where details can be changed.
  • Columns are added and removed for the Add/Edit Board modals.
  • Deleting a board deletes all columns and tasks and requires confirmation.
• Columns
  • A board needs at least one column before tasks can be added. If no columns exist, the "Add New Task" button in the header is disabled.
  • Clicking "Add New Column" opens the "Edit Board" modal where columns are added.
• Tasks
  • Adding a new task adds it to the bottom of the relevant column.
  • Updating a task's status will move the task to the relevant column. If you're taking on the drag-and-drop bonus, dragging a task to a different column will also update the status.

Where to find everything

Your task is to build out the project to the design file provided. We provide both Sketch and Figma versions of the design, so you can choose which tool you prefer to use. You can download the design file on the platform. Please be sure not to share them with anyone else. The design download comes with a README.md file as well to help you get set up.

All the required assets for this project are in the /assets folder. The assets are already exported for the correct screen size and optimized. Some images are reusable at multiple screen sizes. So if you don't see an image in a specific folder, it will typically be in another folder for that page.

We've decided to use a nested data structure for the data.json file, but feel free to alter and flatten the data however you like if you want to change it.

The design system in the design file will give you more information about the various colors, fonts, and styles used in this project. Our fonts always come from Google Fonts.

Building your project

Feel free to use any workflow that you feel comfortable with. Below is a suggested process, but do not feel like you need to follow these steps:

1. Separate the starter-code from the rest of this project and rename it to something meaningful for you. Initialize the codebase as a public repository on GitHub. Creating a repo will make it easier to share your code with the community if you need help. If you're not sure how to do this, have a read-through of this Try Git resource. ⚠️ IMPORTANT ⚠️: There are already a couple of .gitignore files in this project. Please do not remove them or change the content of the files. If you create a brand new project, please use the .gitignore files provided in your new codebase. This is to avoid the accidental upload of the design files to GitHub. With these premium challenges, please be sure not to share the design files in your GitHub repo. Thanks!
2. Configure your repository to publish your code to a web address. This will also be useful if you need some help during a challenge, as you can share the URL for your project with your repo URL. There are a number of ways to do this, and we provide some recommendations below.
3. Look through the designs to start planning out how you'll tackle the project. This step is crucial to help you think ahead for CSS classes to create reusable styles.
4. Before adding any styles, structure your content with HTML. Writing your HTML first can help focus your attention on creating well-structured content.
5. Write out the base styles for your project, including general content styles, such as font-family and font-size.
6. Start adding styles to the top of the page and work down. Only move on to the next section once you're happy you've completed the area you're working on.

Deploying your project

As mentioned above, there are many ways to host your project for free. Our recommended hosts are:

• GitHub Pages
• Vercel
• Netlify

You can host your site using one of these solutions or any of our other trusted providers. Read more about our recommended and trusted hosts.

Create a custom README.md

We strongly recommend overwriting this README.md with a custom one. We've provided a template inside the README-template.md file in this starter code.

The template provides a guide for what to add. A custom README will help you explain your project and reflect on your learnings. Please feel free to edit our template as much as you like.

Once you've added your information to the template, delete this file and rename the README-template.md file to README.md. That will make it show up as your repository's README file.

Submitting your solution

Submit your solution on the platform for the rest of the community to see. Follow our "Complete guide to submitting solutions" for tips on how to do this.

Remember, if you're looking for feedback on your solution, be sure to ask questions when submitting it. The more specific and detailed you are with your questions, the higher the chance you'll get valuable feedback from the community.

⚠️ IMPORTANT ⚠️: With these premium challenges, please be sure not to upload the design files to GitHub when you're submitting to the platform and sharing it around. If you've created a brand new project, the easiest way to do that is to copy across the .gitignore provided in this starter project.

Sharing your solution

There are multiple places you can share your solution:

1. Share your solution page in the #finished-projects channel of the community.
2. Tweet @frontendmentor and mention @frontendmentor, including the repo and live URLs in the tweet. We'd love to take a look at what you've built and help share it around.
3. Share your solution on other social channels like LinkedIn.
4. Blog about your experience building your project. Writing about your workflow, technical choices, and talking through your code is a brilliant way to reinforce what you've learned. Great platforms to write on are dev.to, Hashnode, and CodeNewbie.

We provide templates to help you share your solution once you've submitted it on the platform. Please do edit them and include specific questions when you're looking for feedback.

The more specific you are with your questions the more likely it is that another member of the community will give you feedback.

Got feedback for us?

We love receiving feedback! We're always looking to improve our challenges and our platform. So if you have anything you'd like to mention, please email hi[at]frontendmentor[dot]io.

Have fun building! 🚀
