Automate npm and bower install with grunt
提问by Nick Heiner
I have a node / angular project that uses npm for backend dependency management and bower for frontend dependency management. I'd like to use a grunt task to do both install commands. I haven't been able to figure out how to do it.
我有一个 node/angular 项目，它使用 npm 进行后端依赖管理，使用 bower 进行前端依赖管理。我想使用 grunt 任务来执行这两个安装命令。我一直无法弄清楚该怎么做。
I made an attempt using exec, but it doesn't actually install anything.
我尝试使用exec，但它实际上并没有安装任何东西。
module.exports = function(grunt) {
grunt.registerTask('install', 'install the backend and frontend dependencies', function() {
// adapted from http://www.dzone.com/snippets/execute-unix-command-nodejs
var exec = require('child_process').exec,
sys = require('sys');
function puts(error, stdout, stderr) { console.log(stdout); sys.puts(stdout) }
// assuming this command is run from the root of the repo
exec('bower install', {cwd: './frontend'}, puts);
});
};
When I cdinto frontend, open up node, and run this code from the console, this works fine. What am I doing wrong in the grunt task?
当我cd进入前端时，打开node并从控制台运行此代码，这工作正常。我在 grunt 任务中做错了什么？
(I also tried to use the bower and npm APIs, but couldn't make that work either.)
（我也尝试使用 bower 和 npm API，但也无法使其工作。）

You need to tell grunt that you're using an async method (.exec) by calling the this.async()method, getting a callback, and calling that when exec is done.
您需要.exec通过调用this.async()方法、获取回调并在 exec 完成时调用该方法来告诉 grunt 您正在使用异步方法 ( ) 。
This should work:
这应该有效：
module.exports = function(grunt) {
grunt.registerTask('install', 'install the backend and frontend dependencies', function() {
var exec = require('child_process').exec;
var cb = this.async();
exec('bower install', {cwd: './frontend'}, function(err, stdout, stderr) {
console.log(stdout);
cb();
});
});
};

To install client side components during npm installat the same time than server side libs, you can add in your package.json
要npm install在与服务器端库同时安装客户端组件，您可以添加package.json
"dependencies": {
...
"bower" : ""
},
"scripts": {
...
"postinstall" : "bower install"
}
I prefer to make the difference between install and test/build
我更喜欢区分安装和测试/构建

FYI, here is where i am for now.
仅供参考，这是我现在的位置。
You could also have taken the problem another way, i.e. let npm handle the execution of bower, and ultimately let grunt handle npm. See Use bower with heroku.
你也可以用另一种方式来解决这个问题，即让 npm 处理 bower 的执行，最终让 grunt 处理 npm。请参阅将凉亭与 heroku 结合使用。
grunt.registerTask('install', 'install the backend and frontend dependencies', function() {
var async = require('async');
var exec = require('child_process').exec;
var done = this.async();
var runCmd = function(item, callback) {
process.stdout.write('running "' + item + '"...\n');
var cmd = exec(item);
cmd.stdout.on('data', function (data) {
grunt.log.writeln(data);
});
cmd.stderr.on('data', function (data) {
grunt.log.errorlns(data);
});
cmd.on('exit', function (code) {
if (code !== 0) throw new Error(item + ' failed');
grunt.log.writeln('done\n');
callback();
});
};
async.series({
npm: function(callback){
runCmd('npm install', callback);
},
bower: function(callback){
runCmd('bower install', callback);
}
},
function(err, results) {
if (err) done(false);
done();
});
});

Grunt task that does just this job (as per Sindre's solution above):
