吞咽过程任务的顺序是什么？

本文介绍了吞咽过程任务的顺序是什么？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我对使用Gulp完成任务的顺序感到困惑。请允许我解释一下。 在gulpfile.js中，我拥有所有必需的依赖关系，后跟一组任务。 每个子任务的基本模板是 pre $ g $ p $ gulp.task（'compress：customName'，function（）{ return gulp.src（['app / folder / file.js'，'app / folder / file.js']） .pipe（gp_concat（'app.customName.min.js'）） .pipe（gp_uglify（）） .pipe（gulp.dest（distDir））; }）; 然后，我有一项任务规定它们全部 gulp.task（'compress：all'，['compress：customName1'，'compress：customName2'，'etc ...']，function（）{}）; 然后再添加一个主任务运行者（仅使用compress：全部用于此示例） b $ b gulp.task（'master'，['compress：all']，function（）{ return gulp.src（'dist /*.js'） .pipe（notify（COMPRESSION COMPLETE））; }）; 好的......这是基本的设置......现在来说说这些任务的顺序看起来是完成每个命令行的结果。 [11:06:44]使用gulpfile C：\PATH\ TO \PROJECT\gulpfile.js [11:06:44]开始'compress：customName1'... [11:06:44]开始'compress：customName2'... [11:06:44]开始压缩：customName3'... [11:06:44]开始压缩：customName4'... [11:06:44]开始'compress：customName5'... [11:06:44]开始'compress：customName6'... [11:06:44]开始'compress：customName7'... [11:06:44] 108 ms后完成'compress：customName1' [11:06:44] 93 ms后完成'compress：customName6' [11:06:44]在132 ms后完成'compress：customName5' [11:06:44] 139 ms后完成'compress：customName4' [11:06:44] 233 ms后完成'compress：customName3' [11:06:44] Fin在245 ms之后，压缩：customName2' [11:06:44] 381 ms后完成'compress：customName7' [11:06:44]开始压缩：所有'... [11:06:44]完成'compress：all'6.64 s后 [11:06:44]启动'master'... [11:06:44] gulp-通知：[例如：Gulp Builder] COMPRESSION COMPLETE [11:06:44] 40 ms后完成'master' 为什么'master'是最后一个启动并开始后的任务'compress：all'？ 为什么完成的任务显示在这样的随机顺序？ 为什么说'master'只有40毫秒才能完成，因为它应该等待它调用的所有子任务，然后再考虑完成 解决方案 在实际任务开始之前运行依赖关系。 'compress：all'是依赖于'master'。 依赖关系并行运行，也就是完成一次只取决于完成一次所需的时间。任务完成时间内不包含依赖项。 deps - 在您的任务运行之前要执行并完成的任务数组。 $ b https://github.com/gulpjs/gulp/blob/master/ docs / API.md＃deps I'm a bit confused about the order in which tasks are completed using Gulp. Allow me to explain.In gulpfile.js, I have all my required dependencies followed by a set of tasks.The basic template of each sub task isgulp.task('compress:customName', function() { return gulp.src(['app/folder/file.js', 'app/folder/file.js']) .pipe(gp_concat('app.customName.min.js')) .pipe(gp_uglify()) .pipe(gulp.dest(distDir));});Then, I have a task that rules them allgulp.task('compress:all', [ 'compress:customName1', 'compress:customName2', 'etc...'], function() {});Then one more master task runner (just using compress:all for this example)gulp.task('master', ['compress:all'], function() { return gulp.src('dist/*.js') .pipe(notify("COMPRESSION COMPLETE"));});OK...that's the basic setup...now to talk about the order in which these tasks appear to be completed per the command line results.[11:06:44] Using gulpfile C:\PATH\TO\PROJECT\gulpfile.js[11:06:44] Starting 'compress:customName1'...[11:06:44] Starting 'compress:customName2'...[11:06:44] Starting 'compress:customName3'...[11:06:44] Starting 'compress:customName4'...[11:06:44] Starting 'compress:customName5'...[11:06:44] Starting 'compress:customName6'...[11:06:44] Starting 'compress:customName7'...[11:06:44] Finished 'compress:customName1' after 108 ms[11:06:44] Finished 'compress:customName6' after 93 ms[11:06:44] Finished 'compress:customName5' after 132 ms[11:06:44] Finished 'compress:customName4' after 139 ms[11:06:44] Finished 'compress:customName3' after 233 ms[11:06:44] Finished 'compress:customName2' after 245 ms[11:06:44] Finished 'compress:customName7' after 381 ms[11:06:44] Starting 'compress:all'...[11:06:44] Finished 'compress:all' after 6.64 µs[11:06:44] Starting 'master'...[11:06:44] gulp-notify: [SO EXAMPLE : Gulp Builder] COMPRESSION COMPLETE[11:06:44] Finished 'master' after 40 msHow can 'master' be the last task to start and starts AFTER 'compress:all'?Why are the Finished tasks displaying in such a random order? Why is it that 'master' is said to have completed in only 40 ms when it should be waiting for all the sub-tasks it invokes to respond before considering itself complete? 解决方案 Dependencies are run before actual task is started. 'compress:all' is dependency for 'master'.Dependencies are run in parallel i.e. when one finishes depends only on the time it takes to complete one.Dependencies are not included in the completion time of a task."deps – An array of tasks to be executed and completed before your task will run."https://github.com/gulpjs/gulp/blob/master/docs/API.md#deps 这篇关于吞咽过程任务的顺序是什么？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
