@bazel/node-patches

Runtime modifications to nodejs internals to help node/npm distributed programs run in bazel

fs

patch any fs like object such that symlinks that point outside a specified directory seem to be their targets instead of links

example

const fs = require('fs')
const path = require('path')
const patcher = require('@bazel/node-patches')

patcher.fs(fs,'/my/files')

fs.symlinkSync(path.resolve('./node_modules'),'/my/files/node_modules')

// now try to stat.

const stat = fs.lstatSync('/my/files/node_modules')

console.log(stat.isSymbolicLink() === false)// true

console.log(stat.isDirectory() === true) //true

this should not change the behavior of any paths that are outside of the root.

loader

you can use the register script to include it in a -r flag to preload the patch before user code. This depends on setting the environment variable BAZEL_PATCH_ROOTS

BAZEL_PATCH_ROOTS=~/.cache/bazel node -r @bazel/node-patches/register <your app js>

api

{fs} = require('@bazel/node-patches')

• fs(fsLikeObject: require(‘fs’), root:string)

bazel

to use this package as a dependency in bazel depend on it's exposed file group rule.

:node_patches

this filegroup will always expose one or more files needed to run this package and will not depend on npm install etc.
