【问题描述】:
几天来,我一直在努力解决这个问题,但无法让它按照我需要的方式工作。我找不到其他人使用带有 .net 核心的 Browsersync 的任何示例,这甚至可能是我遇到所有这些问题的原因。但我找不到任何证据证明这一点,也不明白为什么会这样。
无论如何...我的 gulp 文件中的所有内容都完全按照我想要的方式运行,用于 sass/js 处理错误等。我对 gulp 并不陌生,否则我会责怪我缺乏经验我无法让这个工作。
这是我的 gulp 文件,后面是运行 gulp 时的输出。
默认任务:
const gulp = require("gulp"),
uglify = require("gulp-uglify"),
sass = require("gulp-sass"),
rename = require('gulp-rename'),
sassGlob = require('gulp-sass-glob'),
postcss = require('gulp-postcss'),
autoprefixer = require('gulp-autoprefixer'),
sourcemaps = require('gulp-sourcemaps'),
cleanCSS = require('gulp-clean-css'),
concat = require('gulp-concat'),
msbuild = require('gulp-msbuild'),
through = require('through2'),
notifier = require('node-notifier'),
browserSync = require('browser-sync').create();
// Static Server + watching scss/html files
gulp.task('serve', ['sass', 'compileJS'], function() {
browserSync.init({
proxy : {
target: "https://localhost:3000",
},
files: ['./wwwroot/css/*'],
rewriteRules: [
{
match: new RegExp('/css/main.min.css'),
fn: function() {
return './wwwroot/css/main.min.css'
}
}
]
});
//Watch for any changes to the scss files.
gulp.watch('./wwwroot/sass/**/*.scss', ['sass']);
//Watch for any changes to the js files, reload after those changes are made.
gulp.watch('./wwwroot/js/source/*.js', ['compileJS']).on('change', browserSync.reload);
//Watch for any changes to a .cshtml file and reload the browser if/when that change happens.
gulp.watch("./**/*.cshtml").on('change', browserSync.reload);
});
gulp.task('default', ['serve']);
/**
* Compiles SASS files and stores the result into the public folder
*/
gulp.task('sass', function () {
return gulp.src('./wwwroot/sass/main.scss')
.pipe(sassGlob())
.pipe(sass().on('error', function (err) {
console.log('Sass Error:', err.toString());
notifier.notify({
'title': 'Gettin\' Sassy ????♀️',
'message': 'You goofed. Check your terminal window for more information.'
});
this.emit("end");
}))
.pipe(postcss([require('autoprefixer')]))
.pipe(
autoprefixer({
browsers: ['last 2 versions'],
cascade: false
})
)
.pipe(
through.obj(function(chunk, enc, cb) {
cb(null, chunk)
})
)
.pipe(cleanCSS({compatibility: 'ie8',
level: 2}))
.pipe(rename({suffix: '.min'}))
.pipe(gulp.dest('./wwwroot/css'))
.pipe(browserSync.stream());
});
/**
* Compiles the Javascript files and stores the result in the public folder
*/
gulp.task('compileJS', function (done) {
return gulp.src('./wwwroot/js/source/*.js')
.pipe(sourcemaps.init())
.pipe(concat('main.js'))
.pipe(uglify().on('error', function (err) {
console.log('JS Uglify Error:', err.toString());
notifier.notify({
'title': 'JS Compile Error',
'message': 'Something about your JS is a little off. Check yourself before you wreck yourself.'
});
this.emit("end");
}))
.pipe(rename({suffix: '.min'}))
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('./wwwroot/js/dist'));
});
输出:
$ gulp

所以,看着那个输出,你可能会想,“这家伙是个白痴...... Browsersync 声明它正在重新加载浏览器......” 是的,它确实声明了,但它没有重新加载浏览器。 Browsersync 也无法将我的 css 注入浏览器。
正如我所提到的,我以前使用过 gulp,这个设置非常接近于我在进行 Wordpress 开发时使用的 gulp 文件。但是,它不适用于这个项目(这让我对 .net core / Visual Studio 产生了怀疑)。
