問題描述
gulpfile.js
gulpfile.js
gulp.task('browser-bundle', ['react'], function() {
...
});
gulp.task('react', function(){
gulp.src(options.JSX_SOURCE)
.pipe(react())
.pipe(gulp.dest(options.JSX_DEST))
});
如您所見，我有瀏覽器捆綁任務，具體取決于反應任務.我相信這可以按預期工作，因為在輸出中我看到了:
As you can see I have the browser-bundle task depending on the react task. I believe this works as expected because in the output I see this:
[gulp] Running 'react'...
[gulp] Finished 'react' in 3.43 ms
[gulp] Running 'browser-bundle'...
然而，雖然 react 任務已經完成，但它應該寫入操作系統的文件還沒有完全到位.我注意到，如果我在瀏覽器捆綁命令中添加了一個 sleep 語句，那么它會按預期工作，但這對我來說似乎有點 hacky.
However, although the react task is finished, the files its supposed to write to the operating system are not quite there yet. I've notice that if I put a sleep statement in the browser bundle command then it works as expected, however this seems a little hacky to me.
如果我希望在文件(來自 gulp.dest)被同步寫入磁盤之前不認為反應任務完成，我該怎么做?
If I want the react task to not be considered finished until the files (from gulp.dest) have been synchronously written to disk how would I do that?
推薦答案
你需要一個return語句:
You need a return statement:
gulp.task('react', function(){
return gulp.src(options.JSX_SOURCE)
.pipe(react())
.pipe(gulp.dest(options.JSX_DEST))
});
這樣，我所有的寫操作都在下一個任務處理之前完成.
With this all my write operations are done before the next task processed.
