resolve alias

In some lib/subdir1/subdir2/subdir3/foo.js file:

Instead of:

const blah = require("../../../bar.js");

you can do:

const blah = require("$lib/bar.js");

By registering an alias $lib that points to the lib directory.

For example, you might do that in lib/index.js:

const resolveAlias = require("@xarc/resolve-alias");
resolveAlias.add("$lib", __dirname); // make $lib an alias that point to the lib directory

• alias convention:

  1. cannot start with . or be an absolute path.
  2. cannot contain / except if it starts with @, then it can contain one / (ie: npm scope).
  3. cannot contain any space.

• default alias _cwd points to process.cwd()

• alias can provide a function:

resolveAlias.add("_woo", (alias, requestPath, fullRequest) => {
  return "lib";
});

For example: require("@alias/blah/lib/api.js") would call the function with:

1. alias: "@alias/blah"
2. requestPath: "lib/api.js"
3. fullRequest: "@alias/blah/lib/api.js"

enable/disable

resolveAlias.enable = false;

remove

resolveAlias.remove("@foo");
