Simple package for getting alias object for packages managed by lerna, so other tools (such as webpack, rollup, jest and possibly more) can consume your packages directly from the source files, instead of the built and prepared distribution files.
It just eases development and setting up scripts depending on other lerna packages.
lernaAliases({
// from which directory lerna monorepo should be searched for
directory: string = process.cwd(),
// optional array of `mainFields` that should be used to resolv package's entry point
// similar to the https://webpack.js.org/configuration/resolve/#resolve-mainfields
// using this takes precedence over default `sourceDirectory` option
mainFields?: string[],
// which directory should be considered as containing source files of a package
// if specified as false it will use package's root and rely on a tool's (i.e. webpack) resolving algorithm
sourceDirectory: string | false = 'src'
}): AliasesAliases
type Aliases = {
// value is a local directory path to the package
// resolved using `sourceDirectory` and `mainFields` options
[packageName: string]: string,
