opensphere-build-resolver

Resolves sources and other input for the Google Closure Compiler, sass for node-sass, template views for angular, and other items through a project's dependency tree.

Problem

You want to use npm to manage your project and its dependencies, but you need to resolve source, css, sass, templates, or other resources from those dependencies and pass them as arguments on the command line to tools like the google-closure-compiler, node-sass, and others.

Solution

This.

Usage

Install it as a dependency of your package: npm install opensphere-build-resolver --save-dev

Update your package.json to make it an opensphere build project.

"build": {
  "type": "lib", // for libraries, or "app" for applications, "plugin" for plugins, or "config" for config
  "pluggable": false, // whether or not you want the resolver to look for plugins like <packageName>-*
 
  // the rest here are extra options for a specific resolver, in this case the Google Closure Compiler
  "gcc": {
    "js": ['path/to/something/**.js'], // some source that isn't configured in a directory that the gcc resolver will naturally find
    "extra_annotation_name": ["api"]
  } 
},
"scripts": {
  "resolver": "os-resolve someOutputDirectory"
}

Now run npm run resolver and note the output in the given directory. You will want to ensure that your project does not have dependencies that should really be devDependencies (test frameworks, build systems, etc.).

Lib or App Plugins

If your project has

"build": {
  "pluggable": true
}

in its package.json, then the resolver will look for packagename-plugin-yourPlugin modules in:

../
package/node_modules
rootPackage/node_modules

The plugin package should have a peer dependency defined for your package:

"peerDependencies" : {
  "packagename": "^1.2.3"
}

Config Packages

"build": {
  "type": "config"
  "config": "someConfigDirectory" or ["thing1.json", "thing2.json"],
  "priority": 50 // configs are merged from least to greatest
}

Any config value not ending in .json is assumed to be a directory. Configs within directories are merged in lexicographical order.

Dependency Management

While we prefer that all actual source dependencies (such as google-closure-library, openlayers, etc.) or sass dependencies be installed and managed as npm dependencies, the resolver does support bower dependencies as long as they are stored in bower_components in the root of your project.

Writing Plugins

Want to resolve more stuff? Write an opensphere-build-resolver plugin!

Your plugin should be named opensphere-build-resolver-<something> and have a peer dependency on opensphere-build-resolver.

Your plugin should have a opensphere-build-resolver-<something>/index.js file with exports like so:

module.exports = {
  // called for every package in the dependency tree
  resolver: function(currPackageJson, currPackageDirectory, depth): Promise (resolve value does not matter) // optional

  // called once after all packages have resolved
  postResolver: function(basePackageJson, outputDir): Promise (resolve value does not matter) // optional

  // called once after those ^
  writer: function(basePackageJson, outputDir) : Promise (resolve value does not matter) // optional
};
