vscode gulp/grunt 脚本运行 vscode chrome 调试器扩展 [英] vscode gulp / grunt script running vscode chrome debugger extension

问题描述

我是 vscode 和 grunt/gulp 框架的新手，我想知道，是否有可能的方法让您的任务执行某些任务(比如转换一些文件，缩小一些图像等)然后访问 vscode 并运行铬调试器?

I am new to vscode and grunt / gulp frameworks and I was wondering, if there is a possible way for your task to do some task ( let say transpile some files, minify some images etc. ) and then access vscode and run the chrome debugger ?

任何建议我如何做到这一点.

Any advice how I could accomplish that.

推荐答案

这完全取决于您的意思.很容易完成以下工作流程.

It depends on exactly what you mean. It is easy to accomplish the following workflow.

1. 启动一项任务(如 browserSync)，以观察您的文件更改并启动服务器.

2. 通过 .vscode/launch.json 中的启动"命令启动 chrome 调试器扩展，该命令连接到在步骤 1 中启动的同一个 URL.类似

1. Start a task (like browserSync) that watches your file changes and starts a server.

2. Start the chrome debugger extension via a "launch" command in .vscode/launch.json that connects to that same url started in step 1. Something like

{
    "version": "0.1.0",
    "configurations": [
        {
            "name": "Chrome : Launch with sourcemaps",
            "type": "chrome",
            "request": "launch",
            "url": "http://localhost:3000",
            "webRoot": "${workspaceRoot}",
            "sourceMaps": true,
            "runtimeArgs": [
            "--remote-debugging-port=9222"
            ]
        }
}

您的 js 将在您的断点处停止并且现在可以调试了.

Your js will stop at your breakpoints and be debuggable now.

如果您需要有关必要的 gulp 任务的帮助，请告诉我.但这里有一个 gulp.js 代码示例(我在这里使用 gulp4.0，它在 3.x 中不能工作！！):

If you need help with the necessary gulp task let me know. But here is an example gulp.js code (I am using gulp4.0 here, it will not work in 3.x!!):

var gulp = require("gulp");
var browserSync = require("browser-sync").create();
var sass = require("gulp-sass");
// var uglify = require("gulp-uglify");
var concat = require("gulp-concat");
// var rename = require("gulp-rename");
var autoprefixer = require("gulp-autoprefixer");
var cleanCSS = require("gulp-clean-css");
var sourcemaps = require("gulp-sourcemaps");
var cached = require("gulp-cached");
var remember = require("gulp-remember");


function serve(done) {

  browserSync.init({
    server: {
      baseDir: "./",
      index: "home.html"
    },
    ghostMode: false
  });
  done();
}

function reload(done) {
  browserSync.reload();
  done();
}

var paths = {
  styles: {
    src: "./scss/*.scss",
    dest: "./css"
  },
  scripts: {
    src: "./js/*.js",
    dest: "./js"
  }
};

function watch() {
  gulp.watch(paths.scripts.src, gulp.series(processJS, reload));
  gulp.watch(paths.styles.src, gulp.series(sass2css, reload));
  gulp.watch("./*.html").on("change", browserSync.reload);
}

var build = gulp.series(serve, watch);

gulp.task("sync", build);

function sass2css() {
  return gulp.src("./scss/*.scss")
    .pipe(cached("removing scss cached"))
    // .pipe(sourcemaps.init())
    .pipe(sass().on("error", sass.logError))
    // .pipe(sourcemaps.write("./css/sourceMaps"))
    .pipe(gulp.dest("./css"));
}

function processJS() {
  return gulp.src("./js/*.js")
    .pipe(sourcemaps.init())
    // .pipe(concat("concat.js"))
    // .pipe(gulp.dest("./concats/"))
    // .pipe(rename({ suffix: ".min" }))
    // .pipe(uglify())
    .pipe(sourcemaps.write("./maps"))
    // .pipe(gulp.dest("./js"));
}

正如我所写的，您通过 ctr-shift-p 启动任务sync":运行任务并选择 sync

As I have written it, you start the task "sync" by ctr-shift-p : run task and chose sync

然后 - 假设您安装了 chrome 调试器扩展程序 - 通过调试图标启动它:从下拉菜单中选择Chrome : Launch with sourcemaps":并运行它(下拉菜单左侧的小绿色箭头).

Then - assuming you have the chrome debugger extension installed - launch that via the debug icon : chose "Chrome : Launch with sourcemaps" from the dropdown menu : and run it (with the little green arrow to the left of the dropdown menu).

祝你好运.

自从我在 2016 年写下这个答案以来，vscode 增加了使用 compounds 键一次启动多个任务的能力.

Since I wrote this answer 2016, vscode has added the ability to launch multiple tasks at once with the compounds key.

{
    "version": "0.1.0",
    "compounds": [
        {
            "name": "Start server and chrome debugger",
            "configurations": ["Gulp sync", "Chrome : Launch with sourcemaps" ]
        }
    ],
    "configurations": [

        {
            "type": "node",
            "request": "launch",
            "name": "Gulp sync",
            "program": "${workspaceFolder}/node_modules/gulp/bin/gulp.js",
            "args": [
                "sync"
            ]
        },
        {
            "name": "Chrome : Launch with sourcemaps",
            // works with or without preLaunchTask
            "type": "chrome",
            "request": "launch",
            "url": "http://localhost:3000",
            "webRoot": "${workspaceRoot}",

            "sourceMaps": true,
            "runtimeArgs": [
              "--remote-debugging-port=9222"
            ]
        }
}

现在将首先运行 gulp同步"任务，然后在调试模式下启动 Chrome.

will now run the gulp "sync" task first and then launch Chrome in debug mode.

当我使用这个时，我有

 open: false,

在 browserSync 选项中，因此它不会打开额外的默认浏览器窗口(除了即将启动的 chrome).

in the browserSync options so it doesn't open an additional default browser window (besides chrome which is about to be launched).
