当使用Watchify时,Browserify + Babelify Gulp任务不会终止
我在我的Angular项目中使用babelify进行了browserify项目,我在WebStorm中开发了一个gulp任务。 首先,我应该说, 这段代码确实工作得很好 。
我的browserify包如下所示:
const appBundle = browserify({
entries: config.client.src.appModule, // main angular app file
debug: TRUE,
packageCache: {},
cache: {}
}).transform(babelify, {only: './src/client'}).on('log', gutil.log);
我的gulp.task是这样的:
gulp.task('browserify', ['jshint'], function () {
return appBundle.bundle()
.on('error', function (err) {
gutil.log('Browserify error: ' + gutil.colors.red(err.message));
})
.pipe(source('app.js')) // main dist file
.pipe(gulp.dest('./dist'));
});
我根本无法理解的问题 :
我的问题是:为什么我的g task任务在完成工作后没有终止? 我应该始终通过点击我的WebStorm中的方形按钮来手动停止它。
更新1
我发现如果我直接传递“browserify”包,而没有使用变量appBundle ,问题就会消除。 所以代码转向:
browserify({
entries: config.client.src.appModule, // main angular app file
debug: TRUE,
packageCache: {},
cache: {}
}).transform(babelify, {only: './src/client'}).on('log', gutil.log)
.bundle().on('error', function (err) {
gutil.log('Browserify error: ' + gutil.colors.red(err.message));
})
.pipe(source('app.js')) // main dist file
.pipe(gulp.dest('./dist'));
它的工作原理! 但主要困难是我在watchify任务中使用这个appBundle ,所以我不想复制这个包。
更新2
几个小时后,我再次找到了答案 ,这就是我关心的任务。 洞代码是这样的:
const appBundle = browserify({
entries: config.client.src.appModule, // main js file
debug: TRUE,
packageCache: {},
cache: {}
}).transform(babelify, {only: './src/client'});
const b = watchify(appBundle);
function rebundle(bundler) {
return bundler
.bundle()
.on('error', function (err) {
gutil.log('Browserify error: ' + gutil.colors.red(err.message));
})
.pipe(source('app.js'))
.pipe(gulp.dest('./dist'));
}
gulp.task('watchify', function () {
rebundle(b);
b.on('update', function () {
rebundle(b)
});
b.on('log', gutil.log); // output build logs to terminal
});
gulp.task('browserify', ['jshint'], function () {
rebundle(appBundle);
});
当我将const b
声明放入我的监视任务中时,一切都已开始正常工作。
但最后一个问题是:为什么它已经开始运作?
