unrequiredfind unused javascript files
in a big javascript project, sometimes you can forget to delete a unused file.
linters and tree-shakers are good at finding unused code in a module, but they can allow you to have a whole unused file somewhere in your project.
This script follows the require graph, and compares it to the ls output, to find any files that are potentially not being used.
npm install -g unrequired
unrequired ./path/to/my/index.js
or from a node script:
const unrequired = require('unrequired')
let result = unrequired('./tests/mjs/index.js')
console.log(result)
/*
{
all:[ ... ], // all javascript files from a 'ls'
used:[ ... ], // all files in the sourcemap bundle
unused:[], // the diff between the two
}
*/There are probably some caveats to this, but running it may be helpful in a large javascript project.
