Gulp:并行运行多个节点脚本

Question

我有两个服务器脚本(都依赖于socket.io;在不同的端口上运行).

我想通过gulp并行开始.但另外我想有可能阻止其中一个.甚至可能访问每个脚本的控制台输出.

有没有现成的解决方案？或者你甚至建议使用除了吞咽之外的任何东西？

Answer 1

我找到了一个解决方案，其中我另外启动了 mongoDB 服务器：

var child_process = require('child_process');
var nodemon = require('gulp-nodemon');

var processes = {server1: null, server2: null, mongo: null};

gulp.task('start:server', function (cb) {
    // The magic happens here ...
    processes.server1 = nodemon({
        script: "server1.js",
        ext: "js"
    });

    // ... and here
    processes.server2 = nodemon({
        script: "server2.js",
        ext: "js"
    });

    cb(); // For parallel execution accept a callback.
          // For further info see "Async task support" section here:
          // https://github.com/gulpjs/gulp/blob/master/docs/API.md
});

gulp.task('start:mongo', function (cb) {
    processes.mongo = child_process.exec('mongod', function (err, stdout, stderr) {});

    cb();
});

process.on('exit', function () {
    // In case the gulp process is closed (e.g. by pressing [CTRL + C]) stop both processes
    processes.server1.kill();
    processes.server2.kill();
    processes.mongo.kill();
});

gulp.task('run', ['start:mongo', 'start:server']);
gulp.task('default', ['run']);
