Moving gulpfile from CommonJS (CJS) to ECMAScript Modules (ESM)

Context

del v7.0.0 moved to pure ESM (no dual support), which forced me to move my gulpfile to ESM to be able to continue to use del.

The author sindresorhus maintains a lot of npm packages and does not want to provides an upgrade guide for each package so he provided a generic guide. But this guide is a bit vague because it's generic and not helping for gulp, hence this guide.

Guide

Ring handler a function which accepts a request (map) and returns a response (map).

Ring middleware

function (handler, &args -> function(request -> response) because it is a closure handler and &args are in scope within the returned handler function.

a function which accepts a "next handler" (the next handler in the chain) + any extra arguments and returns a handler (function), which will accept a request and return a response.

Se você usa MacOS

O macOs roda sobre Darwin OS (kernel XNU), que é um sistema UNIX-like. Então, todos os comandos abaixo também funcionam normalmente no MacOS. Recomendo utilizar o gerenciador de pacotes homebrew caso necessário instalar algo. Se quiser o mesmo terminal que eu (ZSH com Oh My ZSH), utilize este vídeo para configurar https://youtu.be/bs1-Wxb_KIc

Se você usa Windows

No Windows é possível utilizar o wsl2 e instalar uma versão do linux para acompanhar. Eu fiz alguns vídeos para você usar o Linux no Windows.

Git Branch Merging Best Practices

After you've selected a feature to work on, create a branch in your local repo to build it in.
- $ git checkout -b calaway/short_description_of_feature
Implement the requested feature, make sure all tests are passing, and commit all changes in the new branch.
Checkout the master branch locally.
- $ git checkout master
Pull down the master branch from GitHub to get the most up to date changes from others. If you practice git workflow as described here you should never have a merge conflict at this step.
- $ git pull origin master
Make sure all tests are passing on master and then checkout your new branch.

$ git checkout calaway/short_description_of_feature
