Template repo for starting an Azure Function App with Node.js

About

This template repo contains all the basics for starting a Node.js Azure Function App project

Requirements

• Node.js v20.x (with npm >= v9.x)
• Azure Subscription

Assumptions

• You are familiar with Azure Functions (including how to create them)

Good to know (but not necessary to use this template)

• Dependabot - enabled via ./.github/dependabot.yml
• GitHub Actions Workflows - enabled via ./.github/workflows/*.yml

What's Included

• Minimal Node.js Azure Function App with two example Azure Functions that can be used as starting points (or removed)
• GitHub Actions Workflow that can be configured and used to build and deploy the Function App
• Dependabot.yml configured to check daily for dependency updates
• Example local.settings.json (necessary to configure/run locally)
• Biome config for development
• Some VSCode related files for folks who use it (./.vscode/, ./jsconfig.json)

Example Azure Functions

HTTP Trigger

• Name: http-example
• Description: example of proxying another API, returns JSON output
• Demo: https://ct-azure-function-app-nodejs-starter.azurewebsites.net/api/http-example
  • source API attribution: https://icanhazdadjoke.com/api

Timer Trigger

• Name: timer-example
• Description: cron/scheduled example (console.logs some output every minute)
• Demo: n/a (run locally or deploy to see output)

Getting Started

1. In GitHub, click here (or at the top of the repo click the Use this template button) to create a new repository under your namespace
   • note: you'll be required to give it a name, all other fields can be left alone)

Local Development

1. Clone the new repo to your machine git clone https://github.com/your-username/your-repo-name.git
2. Enter directory cd your-repo-name
3. Install dependencies npm install
4. Setup local.settings.json
   • At minimum, make a copy of example.local.settings.json or Function App won't run locally
     • cp example.local.settings.json local.settings.json
   • note: once you have a Function App setup in Azure, you will want to fill in these values and add any additional you need
5. Run function app locally npm run functions or npm run functions:verbose

Azure Deployment

General

Deployments can be configured however one typically deploys their Function Apps.

For convenience, this template includes a GitHub Action Workflow that (with minimal configuration) can be setup and used to deploy your Function App to Azure.

Configuring Included Workflow for Deployments

1. Before continuing, you will need:
   • The name of the function app you have already created and will be deploying to
   • The publish profile for the function app you will be deploying to
2. Go to repo settings for Actions secrets
3. Click the New repository secret button
   • Name: AZURE_FUNCTIONAPP_PUBLISH_PROFILE
   • Value: use the contents of the function app's publish profile
4. Edit ./.github/workflows/build-and-deploy.yml
   • change the value of FUNCTION_APP_NAME on line 21 to match your function app's name
   • if desired, uncomment the lines that enable automatic deploys on PR merge (see workflow comments)
