本文介绍了在编译完所有文件后,我可以将gulp livereload设置为运行吗?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

我已经有了一大口人来配合Stylus,Jade和tiny-lr。我的问题是,当我保存一个jade文件时,它开始全部编译它们,因此,在我正在处理的文件当前编译之前,实时重新激活第一个文件复制到目标文件,导致我不得不手动刷新。我已经使用gulp-changed修复了这个问题,但我似乎无法配置它或其他东西。任何人有过这个问题吗?我发布了我的Gulp文件,以便您查看。

 'use strict'; 

var gulp = require('gulp');
var jade = require('gulp-jade');
var gutil = require('gulp-util');
var stylus = require('gulp-stylus');
var jeet = require('jeet');
var nib = require('nib');
var uglify = require('gulp-uglify');
var lr = require('tiny-lr')();
// var mainBowerFiles = require('main-bower-files');

//定义源对象
var sources = {
jade:jade / ** / *。jade,
partials:partials / ** / * .jade,
stylus:styl / ** / *。styl,
scripts:js / ** / *。js
};

//定义目标对象

var destinations = {
html:dist /,
css:dist / css,
js:dist / js
};

//编译并复制Jade
gulp.task(jade,function(event){
return gulp.src(sources.jade)
.pipe (jade({
pretty:true
}))。pipe(gulp.dest(destinations.html));
});

编译并复制Stylus
gulp.task(stylus,function(event){
return gulp.src(sources.stylus).pipe(stylus({
使用:[nib(),jeet()],
导入:[
'nib',
'jeet'
],
风格: compressed
}))。pipe(gulp.dest(destinations.css));
});

//缩小和复制所有JavaScript
gulp.task('scripts',function(){
gulp.src(sources.scripts)
.pipe uglify())
.pipe(gulp.dest(destinations.js));
});

//合并Bower文件并复制到/ dist / js /
// gulp.task('bower-files',function(){
// return gulp。 src(mainBowerFiles(/ * options * /),{})
// .pipe(gulp.dest(destinations.js));
//});

//观察文件更改并执行任务
gulp.task(watch,function(){
gulp.watch(sources.jade,[jade] );
gulp.watch(sources.partials,[ 玉]);
gulp.watch(sources.stylus,[ 触笔]);
gulp.watch(源。脚本,[脚本]);
gulp.watch('dist / ** / *',刷新);
});
$ b // Live Reload
gulp.task('serve',function(){
var express = require('express');
var app = express ();
app.use(require('connect-livereload')());
app.use(express.static(__ dirname +'/ dist /'));
app。 listen(4000,'0.0.0.0');
lr.listen(35729);
});

//定义默认任务
gulp.task(default,[jade,stylus,scripts,serve,watch]);

//刷新函数
var refresh = function(event){
var fileName = require('path')。relative(__ dirname,event.path);
gutil.log.apply(gutil,[gutil.colors.magenta(fileName),gutil.colors.cyan('built')]);
lr.changed({
body:{files:[fileName]}
});
};


解决方案

我的gulpfile.js



我这样做是因为当我编译我的sass文件时,livereload将运行10次左右,这种方法只会运行一次。


$ b $ gulpfile.js

  gulp.task('watch',function(){
$ .livereload.listen();

gulp.watch([
path.join(config.path .app,'media / js / ** / *。js'),
path.join(config.path.app,'media / css / ** / * .css'),
path .join(config.path.app,'templates / ** / *。html')
))。on('change',stackReload);

//超时变量
var timer = null;

//实际重载函数
函数stackReload(){
var reload_args =参数;

// Stop如果此函数在最后250ms
内运行,则使用超时函数来运行livereload如果(定时器)clearTimeout(定时器);

//检查是否有任何一饮而尽任务仍在运行
如果(!gulp.isRunning){
定时器= setTimeout的(函数(){
$ .livereload。 changed.apply(null,reload_args);
},250);
}
}

});


I've got a gulp set up to work with Stylus, Jade and tiny-lr. My problem is that when I save one jade file, it start's compiling them all, therefore live reloading fires on the first file copied to the destination, before the file I am working on currently is compiled, resulting in me having to refresh manually. I have fixing this issue using "gulp-changed" but I don't seem to be able to configure it or something. Anyone had this problem before? I am posting my Gulp file so you can take a look.

Any help is appreciated!

解决方案

I have achieve this by writing a simple javascript function in my gulpfile.js

I did this because when I compile my sass files, livereload will run around 10 times, this method will make it only run once.

My gulpfile.js

gulp.task('watch', function() {
    $.livereload.listen();

    gulp.watch([
        path.join(config.path.app, 'media/js/**/*.js'),
        path.join(config.path.app, 'media/css/**/*.css'),
        path.join(config.path.app, 'templates/**/*.html')
    ]).on('change', stackReload);

    // a timeout variable
    var timer = null;

    // actual reload function
    function stackReload() {
        var reload_args = arguments;

        // Stop timeout function to run livereload if this function is ran within the last 250ms
        if (timer) clearTimeout(timer);

        // Check if any gulp task is still running
        if (!gulp.isRunning) {
            timer = setTimeout(function() {
                $.livereload.changed.apply(null, reload_args);
            }, 250);
        }
    }

});
