exec-with-verify

asynchronously exec child processes and verify that a string is printed to stdout

Expects a configuration that includes a cmd to execute, the working directory, and an optional verification string.

execWithVerify returns a promise that will resolve/reject upon process completion.

Installation: npm install exec-with-verify

Example config:

var config = { cmd: 'ng build --prod', cwd: 'src/main/js/myapp', successString: 'Built project successfully'};

var execV = require('exec-with-verify');
execV.execWithVerify(config);

The config may be a single config object or an array. If it's an array, the child processes will be executed concurrently.

Gulp Example: task that builds a group of angular 2 apps with angular-cli

var apps = [ 'src/main/js/myapp1', 'src/main/js/myapp2' ];

gulp.task('ng:build', function() {

    var execV = require('exec-with-verify');

    var configs = apps.map(function(app) {
            return { cmd: 'ng build --prod', cwd: app, successString: 'Built project successfully'};
        });

    return execV.execWithVerify(configs);
});
