action-hosting-deploy VS lint-staged

Could they not have their own FB to develop against? Does every dev need to use just yours? If that is the case, then you'd need to use https://support.google.com/firebase/answer/7000272?hl=en also, it looks to be possible to include Firebase in your GitHub for them to pull from https://firebase.google.com/docs/hosting/github-integration

Github Actions is the way to go for this: https://firebase.google.com/docs/hosting/github-integration

Whenever a Pull Request is created we need to be able to quickly checkout the changes. Reading code diff is great, but sometimes you just need to tinker with the new version, test it on mobile, different browsers and OS. Cloud services are perfect for this case, they allow you to deploy the code temporarily and access it with a link from any device. We chose Firebase to host it for us and a Github action posts a link to the deployment as a comment in the Pull Request. It works like a charm and speeds up code reviews a lot. Read this article to set it up on your repository!

Lambdas and firebase on the GCP stack for CRUD apps.

One nice thing about firebase -> each PR deploys to its own preview channel[1].

Downside: Very JS heavy. I write lambdas in python though.

Google Firebase has a pretty straightforward guide to setting up auto-deploy from Github, which you can take a look at here: https://firebase.google.com/docs/hosting/github-integration

What is the easiest way for setting up CI/CD from GH for Firebase functions? Maybe something like this for hosting, but only for functions?

Lint Staged: https://github.com/lint-staged/lint-staged

lint-staged is the second important tools we need here, install it via NPM.

We were already using lint-staged and have a pre-commit hook in place using Husky in our project for linter and prettier. So it made sense to add a check here.

Now you can config it in your package.json, here is the guide doc:

In the world of software development, maintaining consistent code quality and ensuring that the codebase adheres to predefined patterns and guidelines is crucial. However, manually enforcing these standards can be time-consuming and error-prone. This is where automation tools like Husky, Lint-Staged, Commitlint, and Commitizen come to the rescue. In this post, we will explore how these tools can be combined to streamline your development workflow.

This is wasted work that can and should be automated. Adding a linter and formatter on CI and a pre-commit hook such as lint-staged can do wonders.

lint-staged is a package that can be used to run formatting and linting commands on staged files in a Git repo.

To answer your next question: I lint and format on save, and I use Git hooks installed by Husky and executed through Lint-Staged (this tool helps ensure your Git hooks only run on modified files, etc) to ensure there are no lint or formatting errors whenever making a commit or pushing code. This is helpful for teams, as some developers tend to forget to run lint tasks, or don't have the Prettier extension installed in their IDE. If there are lint errors, the commit is rejected until fixed. YMMV - you'll need to fine-tune the strictness of this based on the team's needs.

Uses Husky Git hooks and Lint-staged pre-commit hooks.

Something else to consider is applying linting and formatting before every git commit. A package like Lint-staged only lints and formats on staged items, ensuring all pushed code follows the standards in the repo. This allows developers to have their own formatting preferences when developing, while the code homogenizes on push. Linting pre-commit also avoids strict rules like no-console or no-unused-vars restricting a developer when writing code, when it should only apply in production. Imagine not being able to console log anything during development!
