How make bower build the package?

问题

Is there a way to make bower run a package grunt after it was cloned from GitHub?

I'm trying to use Bower but one of the packages I'm using is the Bootstrap extension, x-editable. The problem is that while other packages push a fully built version to github so when installed by Bower you have a built version x-editable expect you to run a grunt file to build the package.

That is a common practice in other package managers like npm but I could find how to make Bower build it on install. Which means I need another mechanism to complete the installation of the package.

回答1:

Building on install is an anti-pattern and is strongly recommended against in Node. Like Node, Bower packages should be pre-built. This is because the end-user shouldn't have to care what preprocessor or build-system a package requires.

Your best options are to either convince the author to pre-build, fork and do it yourself, or build manually after you've installed the component.

The Bower team is planning to add the ability to publish packages to a server similar to how it works in npm. This will make it much better for packages needing a build-step.

There are 3 hooks in bower, postinstall may solve your problem if for whatever reason you can not pre-built like @Sindre Sorhus points out.

In .bowerrc do:

{
    "scripts": {
        "preinstall": "<your command here>",
        "postinstall": "<your command here>",
        "preuninstall": "<your command here>"
    }
}

You could use composer for handling post install:

bower.json:

{
    "dependencies": {
        "bootstrap": "*"
    }
}

composer.json:

{
    "scripts" : {
        "post-install-cmd" : [
            "bower install --no-color",
            "lessc bower_components/bootstrap/less/bootstrap.less public/script/bootstrap.css"
        ]
    }
}

Then I run composer install:

Loading composer repositories with package information
Installing dependencies (including require-dev)
Nothing to install or update
Generating autoload files
bower warn Package bootstrap is still using the deprecated "component.json" file
bower cloning git://github.com/twitter/bootstrap.git

bower installing bootstrap#2.3.2
bower installing jquery#1.8.3

After Bower finishes installing, the LESS compiler processes the .less files and puts a nice bootstrap.css in my public folder. something similar could be done for JavaScript files with Closure Compiler.
