GitHub Actions
Introduction In this post, I’ll show you how one GitHub Actions workflow from a repository can invoke a workflow from a different repository. The first part describes the different events that can trigger a workflow, focusing on the repository_dispatch event. The second part is a practical example showing how two repositories trigger their workflows mutually. Events that trigger workflows As you may already know, there are several events that can trigger a GitHub Actions workflow execution. The most common events that can trigger this execution are push, pull_request and schedule. These events cover most of the use cases, as regularly […]

Webpack ReactJS Gatsby
Introduction Gatsby is static site generator platform based in ReactJS and powered by GraphQL. I’ve been using Gatsby for a while now and most recently used it to rebuild my personal homepage. One of the things that has come to my attention is that transpiled Javascript source maps are published to production builds by default in V2.

In this post we’ll see how we can configure Gatsby to publish source maps […]

react webpack babel sass mn
Introduction Babel 7 comes after more than 2 years of active development and four thousand commits. The main advantage of the new version is the speed optimizations and configuration flexibility. In this tutorial we’ll see how to upgrade our React boilerplate application to support Babel 7. Bebel dependencies The first step in order to support Babel 7 is to replace our old dependencies in package.json: [crayon-5f0c67fc52dbb951678509/] with new ones: [crayon-5f0c67fc52dce535231882/] The main change compared to the older version is Babel’s switch to scoped packages. To summarize, from now on most of the packages named with the prefix babel- will now be named […]
