fedep

Frontend dependency installer. copy frontend modules to desired directory, with additional configurations in package.json:

"scripts": { ... "postinstall": "./node_modules/.bin/fedep" }, "frontendDependencies": { "root": "web/static/assets/lib", "modules": [ "ldLazy" ] }

by executing npx fedep or invoking via postinstall when npm i, fedep will do:

• lookup package with given name in node_modules folder.
• once found, copy content to <root>/<name>/<version> from folders of give source packages in following priority:
  • <dir> folder if dir option is given ( see below ).
  • dist folder if <dir> is omitted, dist exists and --use-dist option is set to true.
  • otherwise, the whole package is copied.
• build a symbolic link from to /main/

Once configuration is prepared, run:

npx fedep

for a quick setup of frontendDependencies field, run:

npx fedep init

you still have to update its fields according to what you need.

Additionally, you can also use local repo for a specific module:

npx fedep -l <some-module>:<path-to-local-repo>

Use semi comma ; to separate multiple pairs of local repos:

npx fedep -l "mod1:path-to-mod1;mod2:path-to-mod2;mod3:path-to-mod3"

Modules Format

you can use either string or object to list modules to be used. e.g.,

["ldLazy", ...,  {name: "ldview"}, ...]

If object is used, it contains following fields:

• name: module name
• browserify: true/object if browserify this module.
  • if it's an object, the object will be passed to browserify as it's option object.
• dir: subdir to copy in this module. default the whole module, if not specified
• link: set true to use symlink instead of copying. default false.
  • always false if browserify is set to true.
• transpile: add this object if you need to transpile module file, which contains following fields:
  • files: a list of file to transpile.
• optional: default false. if true, ignore this entry if it can't be found, even if it's not in optionalDependencies.

Publish

Use npx fedep publish to publish based on dist folder along with core files such as package.json. For example, say you have following directory structure:

• dist
  • index.js
• README.md
• CHANGELOG.md
• package.json
• LICENSE

npx fedep publish merge above content into .fedep/publish as below:

• .fedep/publish
  • index.js
  • README.md
  • CHANGELOG.md
  • package.json
  • LICENSE

and trigger npm publish --access public .fedep/publish. Additionally, npx fedep publish also alters copied package.json with following changes to reflect the change of the directory structure:

• files field removed
• file path in following fields are converted from relative to root to relative to dist:
  • style, browser, module, main, unpkg

publish command also publish files listed in files field, with their original directory structure, except dist folder. dist is by default removed with its content moved to root. To keep dist folder, use --dup true option:

npx fedep publish --dup true

You can also use a different dist folder by folder option:

npx fedep publish --folder another-dist
