Gulp-file-include 不适用于 gulp.watch

Question

我想使用 gulp-file-include 到 assemble 来自不同 HTML 文件的 index.html。 dist 文件夹包含所有生产文件。问题是 gulp-watch 无法识别 HTML 文件是否已更改，因此当我运行观看时，dist 文件夹中的 HTML 文件将不会更新。

如何自定义 gulp 以便 gulp-watch 也能实时检测到这些变化？

Answer 1

尝试更改：

gulp.watch("./**/*.html", browserSyncReload);

至

gulp.watch("./src/**/*.html", browserSyncReload);

Answer 2

BrowserSync 很棒，但似乎总是很难按您想要的方式获得它运行！我最终创建了一个小测试项目来调试你的 gulpfile.js

这是您的代码的经过测试的工作版本，注释如下：

'use strict';

// Load plugins
const autoprefixer = require('gulp-autoprefixer');
const browserSync = require('browser-sync').create();
const cleanCSS = require('gulp-clean-css');
const del = require('del');
const gulp = require('gulp');
const header = require('gulp-header');
const merge = require('merge-stream');
const plumber = require('gulp-plumber');
const rename = require('gulp-rename');
const sass = require('gulp-sass');
const uglify = require('gulp-uglify');
const fileinclude = require('gulp-file-include');

// Load package.json for banner
const pkg = require('./package.json');

// BrowserSync
function server(done) {
    browserSync.init({
        server: {
            baseDir: './dist/'
        },
        port: 3000
    });
    done();
}

// server reload
function browserSyncReload(done) {
  browserSync.reload();
  done();
};

// Clean vendor
function clean() {
    return del(['./dist/vendor/']);
}

// Bring third party dependencies from node_modules into vendor directory
function modules() {
    // Bootstrap
    var bootstrap = gulp.src('./node_modules/bootstrap/dist/**/*')
        .pipe(gulp.dest('./dist/vendor/bootstrap'));
    // Font Awesome CSS
    var fontAwesomeCSS = gulp.src('./node_modules/@fortawesome/fontawesome-free/css/**/*')
        .pipe(gulp.dest('./dist/vendor/fontawesome-free/css'));
    // Font Awesome Webfonts
    var fontAwesomeWebfonts = gulp.src('./node_modules/@fortawesome/fontawesome-free/webfonts/**/*')
        .pipe(gulp.dest('./dist/vendor/fontawesome-free/webfonts'));
    // jQuery Easing
    var jqueryEasing = gulp.src('./node_modules/jquery.easing/*.js')
        .pipe(gulp.dest('./dist/vendor/jquery-easing'));
    // jQuery
    var jquery = gulp.src([
        './node_modules/jquery/dist/*',
        '!./node_modules/jquery/dist/core.js'
    ])
        .pipe(gulp.dest('./dist/vendor/jquery'));
    return merge(bootstrap, fontAwesomeCSS, fontAwesomeWebfonts, jquery, jqueryEasing);
}

// CSS task
function css() {
    return gulp
        .src('./res/scss/**/*.scss')
        .pipe(plumber())
        .pipe(sass({
            outputStyle: 'expanded',
            includePaths: './node_modules',
        }))
        .on('error', sass.logError)
        .pipe(autoprefixer({
            cascade: false
        }))
        .pipe(header(banner, {
            pkg: pkg
        }))
        .pipe(gulp.dest('./dist/css'))
        .pipe(rename({
            suffix: '.min'
        }))
        .pipe(cleanCSS())
        .pipe(gulp.dest('./dist/css'))
        .pipe(browserSync.stream({match: '**/*.css'}));
}

// JS task
function js() {
    return gulp
        .src([
            './res/js/*.js',
            '!./res/js/*.min.js',
            '!./res/js/contact_me.js',
            '!./res/js/jqBootstrapValidation.js'
        ])
        .pipe(uglify())
        .pipe(header(banner, {
            pkg: pkg
        }))
        .pipe(rename({
            suffix: '.min'
        }))
        .pipe(gulp.dest('./dist/js'));
}

function html() {
    return gulp
        .src(['index.html'])
        .pipe(fileinclude({
            prefix: '@@',
            basepath: '@file'
        }))
        .pipe(gulp.dest('./dist/'));
}

// Watch files
function watchFiles() {
    gulp.watch('./res/scss/**/*', css);
    gulp.watch(['./res/js/**/*', '!./dist/js/**/*.min.js'], gulp.series(js, browserSyncReload));
    gulp.watch(['./src/**/*.html', 'index.html'], gulp.series(html, browserSyncReload));
}

// Define complex tasks
const vendor = gulp.series(clean, modules);
const build = gulp.series(vendor, gulp.parallel(css, js, html));
const watch = gulp.series(build, server, watchFiles);

// Export tasks
exports.css = css;
exports.js = js;
exports.html = html;
exports.clean = clean;
exports.vendor = vendor;
exports.build = build;
exports.watch = watch;
exports.browserSyncReload = browserSyncReload;
exports.server = server;
exports.default = build;

只需更改几位即可使其正常工作：

我认为您看到的主要问题是您没有在更改时重新编译 html，它只是重新加载浏览器。我已将手表 html 从：gulp.watch('./**/*.html', browserSyncReload); 更新为：gulp.watch(['./src/**/*.html', 'index.html'], gulp.series(html, browserSyncReload));
stream 用于将代码注入页面，因此对于 html 和 js 将无法正常工作，因此我已将其从任务并替换为监视任务中的 reload。
需要 browserSyncReload 和 server 的导出
watchFiles 和 browserSync 并行运行时似乎存在竞争问题，所以他们现在运行串联。即：先建服务器，再看文件。

不需要但在此过程中发生的更改：

有一个名为 browserSync 的函数和一个名为 browsersync 的常量让我感到困惑，因此该函数已重命名为 server 并且常量现在为 browserSync。
我的编辑器配置将所有引号设置为单引号，而不是混合引号。
我已将 css 任务中的 stream 设置为仅 match: '**/*.css'
