The Problem: A GitHub Action Workflow that Refuses to Deploy
You’ve written a fantastic Angular 18 app, and you’re excited to share it with the world. You’ve set up a GitHub Action workflow to build and publish your app to GitHub Pages, but for some reason, it just won’t deploy. You’ve checked the logs, and all you see is a cryptic error message that doesn’t give you any clues about what’s going wrong.
Don’t worry, we’ve all been there! In this article, we’ll take a closer look at the most common issues that can cause your GitHub Action workflow to fail and provide a comprehensive guide to building and publishing your Angular 18 app to GitHub Pages.
Prerequisites: What You Need to Get Started
Before we dive into the meat of the article, let’s make sure you have the following prerequisites in place:
-
An Angular 18 project set up with GitHub
-
A GitHub Actions workflow file (
yml
file) in the root of your repository -
A GitHub Pages site set up for your repository
Step 1: Check Your GitHub Action Workflow File
The first step in troubleshooting your GitHub Action workflow is to take a closer look at your workflow file. Open the file in your favorite code editor and make sure you have the following sections:
name: Build and Deploy to GitHub Pages
on:
push:
branches:
- main
jobs:
build-and-deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Install dependencies
run: npm install
- name: Build and deploy
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
REPOSITORY_NAME: ${{ github.repository }}
run: |
npm run build
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
git remote add origin https://github.com/${REPOSITORY_NAME}.git
git push --force origin main:gh-pages
Make sure you’ve replaced [email protected]
and Your Name
with your actual email and name.
Step 2: Verify Your GitHub Pages Setup
In this step, we’ll make sure your GitHub Pages setup is correct:
1. Go to your repository on GitHub and click on the Settings
tab.
2. Scroll down to the Github Pages
section.
3. Make sure the GitHub Pages
switch is turned on.
4. Select the branch that you want to use for your GitHub Pages site (in this case, we’re using the gh-pages
branch).
5. Click Save changes
.
Step 3: Check Your Angular 18 App Configuration
In this step, we’ll verify that your Angular 18 app is configured correctly:
1. Open your angular.json
file and make sure the outputPath
is set to dist
.
{
"projects": {
"your-app": {
...
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
...
"outputPath": "dist",
...
},
...
},
...
}
}
}
}
2. Make sure your tsconfig.json
file is configured correctly:
{
"compilerOptions": {
...
"outDir": "dist",
...
}
}
Step 4: Troubleshoot Your GitHub Action Workflow Logs
In this step, we’ll take a closer look at your GitHub Action workflow logs to identify any errors:
1. Go to your repository on GitHub and click on the Actions
tab.
2. Find the workflow run that failed and click on it.
3. Click on the Build and deploy
job.
4. Scroll down to the Log
section.
5. Look for any error messages that might give you a clue about what’s going wrong.
Common Errors and Solutions
Here are some common errors you might encounter and their solutions:
Error Message | Solution |
---|---|
Error: Cannot find module '@angular-devkit/build-angular' |
Run npm install @angular-devkit/build-angular in your repository root. |
Error: Cannot find module 'rxjs' |
Run npm install rxjs in your repository root. |
Error: GitHub Pages site not found |
Verify that your GitHub Pages setup is correct (see Step 2). |
Error: Permission denied |
Make sure you have the correct permissions set up for your GitHub Actions workflow. |
Conclusion
And that’s it! By following these steps, you should be able to troubleshoot and fix your GitHub Action workflow to build and publish your Angular 18 app to GitHub Pages. Remember to double-check your workflow file, GitHub Pages setup, and Angular 18 app configuration, and don’t be afraid to dig into your workflow logs to identify any errors.
Happy coding, and I hope this article has helped you solve the mystery of the failing GitHub Action workflow!
