使用指定一个普通任务和一个监视任务

Question

在本地开发期间，我使用Watchify (通过grunt-browserify)进行快速编译：

grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    browserify: {
        app: {
            src: './src/app.js',
            dest: 'build/js/app.js'
        },
        options: {
            // next two lines for watchify + watch instead of browserify
            watch: true,
            keepAlive: true,
            transform: ['node-lessify', 'node-underscorify'],
            debug: true,
            browserifyOptions: {
                debug:true // include source maps.  currently only available with browserify
            }
        }
    }
}

grunt.loadNpmTasks('grunt-browserify');

运行grunt browserify将进入一个while true循环，该循环持续监视更改。当涉及到构建一个生产准备包时，我希望它只运行一次，而不是观看。

我尝试过此配置，但browserify:dev任务从未监视过：

grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    browserify: {
        dev: {
            src: './src/app.js',
            dest: 'build/js/app.js',
            // next two lines for watchify + watch instead of browserify
            watch: true,
            keepAlive: true
        },
        package: {
            src: './src/app.js',
            dest: 'build/js/app.js'
        },
        options: {
            transform: ['node-lessify', 'node-underscorify'],
            browserifyOptions: {
                debug:true // include source maps.  currently only available with browserify
            }
        }
    }
});

如何指定使用Watchify监视的Browserify任务和构建整个包和退出的任务？

我的配置错了。请注意，keepAlive: false位于browserify:package作业的options名称空间中：

grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    browserify: {
        dev: {
            src: './src/app.js',
            dest: 'build/js/app.js'
        },
        package: {
            src: './src/app.js',
            dest: 'build/js/app.js',
            options: {
                keepAlive: false
            }
        },
        options: {
            watch: true,
            keepAlive: true,
            transform: ['node-lessify', 'node-underscorify'],
            browserifyOptions: {
                debug:true // include source maps.  currently only available with browserify
            }
        }
    }
});
