metro VS starter-workflows

For details on the implementation you can see Evan's PR to metro here.

Some development tools for the web are similar (Chrome debugger, mostly) to those for React Native, but other aspects are very different (working with the metro bundler, using Flipper, AsyncStorage debugging, more). Some techniques developers will use are the same (breakpoints and console logging), but others are different (knowing when to restart the packager vs reinstall the app on device).

We’re almost done with setting up the project. The last thing in the React Native app is to add watchFolders so metro knows where the linked node_modules are. The shared modules are symlinked by yarn, and since metro doesn’t follow symlinks we need to explicitly say it where the linked node_modules are.

Unfortunately it is what it is... I use intellij instead of webstorm since they're the same thing basically. I spent a shitton of time figuring out how to link a local package i was creating for my app only to discover about this issue that is almost as old as react native itself. (luckily there's rnx-kit that solves the problem). Not to talk about the impossibility to have one goddamn IDE to write both typescript, java and c++. Currently i have to write ts/js in intellij, then i have to switch to android studio to write java/c++.

React Native packager. Override instructions here.

React Native doesn't play nicely with most monorepo tools out of the box as Metro doesn't support symlinking.

Because React Native for Web is a React website, you can use front-end tools to build and run it. For example, you can build it with Webpack or Rollup instead of Metro bundler.

Before we can run the app, we still need do one more thing: make metro bundler compatible with Yarn workspaces' hoisting.

Second, sharing code with other projects (e.g., backend code, web apps) may get complicated. Out-of-the-box, React Native's metro bundler cannot reference code outside of the project's root directory. You can configure it to do so (and we'll do it as well later on). Still, once you do it, you'll also need to ensure dependencies resolution works correctly (to avoid loading two different versions of the same library, for example); which might not be as easy as it may sound.

GitHub, as one of the leading web-based Git repository hosting service, provides a powerful suite of CI/CD tools in the form of GitHub Actions. These are directly integrated into the platform which empowers developers to increase the speed, efficiency and reliability of delivering products. In this brief article, we will take a look at what CI/CD is, why we should use it, as well as some of its applications in my projects.

GitHub Actions is a modern CI/CD tool integrated natively on GitHub. Itenables the rapid automation of build, test, deployment, and other custom workflows on GitHub with no need for external tools.

GitHub Actions is GitHub's CI/CD solution. You can use it to run automated tasks each time you change your code. Although the platform lacks a built-in Kubernetes integration, third-party plugins such as Azure's Deploy to Kubernetes Cluster action can automate deployments and manage different rollout strategies.

GitHub Actions is a feature-rich CI/CD platform embedded within GitHub, enabling developers to automate, customize, and execute software development workflows directly in their repositories. An Action inside GitHub Actions is a discrete unit of automation that performs a specific task within a workflow. All the Actions are reusable, and there are many to choose from. You can even create your own reusable ones.

The real power of using PHP code-quality tools is when it’s added to your continuous integration process, which means it automatically checks the code every time someone makes a push or pull request to your project repo. In this section, we'll be looking at how to do just that. GitHub actions is available for free so we'll use it for demo purposes. Note that there are some limits to private repos, so set your test repo to public if you can.

You can even automate the running of this script — hence the directory name automation — to happen every time the data changes, using GitHub Actions.

You might remember that I’ve been taking an interest in GitHub Actions for the last year or so (I even wrote a book on the subject). And at the Perl Conference in Toronto last summer I gave a talk called “GitHub Actions for Perl Development” (here are the slides and the video).
