Trigger deploys on Netlify with submodules

⭐️ 👀 2023 WEB DEVELOPMENT BOOTCAMP starting in days! Join the waiting list to reserve your spot in my 10-weeks cohort course and learn the fundamentals, HTML, CSS, JS, Tailwind, React, Next.js and much much more! 👀 ⭐️

I wanted to rebuild my site on Netlify any time I did a new commit on a Git submodule included in the repo.

Unfortunately Netlify does not do this by default, only the main repository is “watched” for new commits.

So I did this.

I went in the Deploy settings and in “Build hooks” I clicked “Add build hook”.

Saving this gave me a unique URL I could call, something like https://api.netlify.com/build_hooks/UNIQUE_STRING.

Then I created a GitHub Action in the submodule repository:

name: Trigger redeploy on Netlify
on:
  push:
    branches: [ "main" ]
jobs:
  build:
    name: Make POST request
    runs-on: ubuntu-latest
    steps:
      - name: Curl request
        shell: bash
        env:
          UNIQUE_STRING: ${{ secrets.NETLIFY_BUILD_HOOK_UNIQUE_STRING }}
        run: curl -X POST -d {} https://api.netlify.com/build_hooks/$UNIQUE_STRING

Add the value of the Netlify UNIQUE_STRING value you to above in NETLIFY_BUILD_HOOK_UNIQUE_STRING Action secret in your repo Settings -> Secrets -> Actions.

Commit the action and the deploy should already be working:

One more thing! ⚠️ ✋

At the end of January I will organize the Web Development Bootcamp.

It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.

It's not "just a course". It's a big event I organize once a year.

We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more! 

At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.

Because once you got the fundamentals, you only learn by working on real, exciting projects.
