in your linked module names, there is a risk this module will cause data loss
If you use See this issue #3
link-module-alias
Setup private modules within your repo to get away from error-prone typing of long relative paths like these:
require('../../../../some/very/deep/module')
Just create an alias and do it cleanly:
var module = require('@deep/module')
// Or ES6
import module from '@deep/module'
You can setup aliases both to individual files and to directories.
WARNING Use this module only in final applications. It will not work inside published npm packages.
Install
npm i --save-dev link-module-alias
Usage
Add your custom configuration to your package.json
(in your application's root), and setup automatic initialization in your scripts section.
Note: you can use @
in front of your module but before of the possible data loss #3
"scripts": {
"postinstall": "link-module-alias"
},
// Aliases
"_moduleAliases": {
"~root" : ".", // Application's root
"~deep" : "src/some/very/deep/directory/or/file",
"@my_module" : "lib/some-file.js", // can be @ - but see above comment and understand the associated risk
"something" : "src/foo", // Or without ~. Actually, it could be any string
"module-with-typings": {
"main": "src/path/to/module.js",
"typings" "src/path/to/module/typings.d.ts" // you can specify typings for files (it works with aliases to files only)
}
}
If you encounter issues with installing modules, you may want to set up the preinstall script as well:
"scripts": {
"postinstall": "link-module-alias",
"preinstall": "command -v link-module-alias && link-module-alias clean || true"
}
How does it work?
- For aliases to directories, we create symlinks with
fs.symlink
- For aliases to files, we create proxy modules with a package.json containing
"main"
that points to the target file
Background
This module it's almost a drop in replacement for another package https://www.npmjs.com/package/module-alias - use module module-alias
if you like runtime require hooks and use link-module-alias
if you want good compatibility with your IDE and no runtime hacks.
The key differentiator of link-module-alias
is creating all the module links statically in form of symlinks and proxy packages inside node_modules
, there is no hacky require hook and you don't need to load any supporting packages.
The key motivator to create link-module-alias
was to fix the issue with module aliases not resolving in VS Code. ilearnio/module-alias#19
