Auto-deploying React and Vue apps with Heroku involves setting up a continuous integration (CI) and continuous deployment (CD) pipeline using a version control system (such as Git), a CI/CD tool (such as GitHub Actions), and the Heroku platform. This allows you to automatically build and deploy your apps whenever you push changes to your repository. Here’s a general guide on how to achieve this:

Getting Started

Requirements:

• Node.js set up
• Heroku Account
• Github Account

1. Set Up Your Version Control Repository:

Create a repository on a version control platform like GitHub or GitLab. Make sure your React or Vue app’s source code is in this repository.

git add . && git commit “initial commit” && git push origin master

2. Configure Your Local Development Environment:

Ensure that your React or Vue app is properly configured for deployment. This may involve setting up build scripts, environment variables, and other necessary configurations.

3. Set Up a Heroku Account:

If you don’t have a Heroku account, sign up for one at https://www.heroku.com/. Install the Heroku CLI on your local machine to interact with Heroku services.

4. Create a Heroku App:

In your Heroku dashboard, create a new app. This app will be used to host your React or Vue app.

5. Configure Heroku Deployment:

For React apps:

• In your app’s root directory, create a static.json file to configure your build settings for Heroku. You might also need a Procfile to define the server process.

For Vue apps:

• Configure your Vue app’s package.json with a "postinstall" script that builds your app.

6. Set Up Continuous Integration (CI):

Choose a CI/CD tool like GitHub Actions. Create a .github/workflows directory in your repository and add a YAML file for your CI/CD workflow configuration.

Here’s a basic example of a GitHub Actions workflow YAML for a React app (react-ci-cd.yml):

name: CI/CD for React App

on:
push:
branches:
– main

jobs:
build:
runs-on: ubuntu-latest

steps:
– name: Checkout Repository
uses: actions/checkout@v2

– name: Install Dependencies
run: npm install

– name: Build App
run: npm run build

– name: Deploy to Heroku
uses: akhileshns/heroku-deploy@v3.12.12
with:
heroku_api_key: ${{ secrets.HEROKU_API_KEY }}
heroku_app_name: your-heroku-app-name

7. Set Up Heroku API Key:

In your GitHub repository, go to “Settings” > “Secrets” and add a secret named HEROKU_API_KEY with your Heroku API key.

8. Push Changes and Deploy:

When you push changes to your repository’s main branch, GitHub Actions will automatically trigger the CI/CD workflow. It will build your app and deploy it to Heroku

9. Monitor Deployment:

Monitor the GitHub Actions workflow for any errors during the build and deployment process. You can also check the Heroku dashboard for logs and information about the deployment process.

With these steps, you’ll have an automated CI/CD pipeline in place that builds and deploys your React or Vue app to Heroku whenever you push changes to your repository. Make sure to adjust the configurations based on your specific app and requirements.
