Gulp Livereload after ALL files have been compiled? - javascript

I have a problem that I thought might be common to many people, but it seems I'm not right. So I hope someone can help, since I can't find the answer in the Gulp documents.
Right now my gulpfile.js has the following content:
'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 livereload = require('gulp-livereload');
var sources = {
jade: "jade/**/*.jade",
partials: "partials/**/*.jade",
stylus: "styl/**/*.styl",
scripts: "js/**/*.js"
};
// Define destinations object
var destinations = {
html: "dist/",
css: "dist/css",
js: "dist/js"
};
// Compile and copy Jade
gulp.task("jade", function(event) {
return gulp.src(sources.jade)
.pipe(jade({pretty: true}))
.pipe(gulp.dest(destinations.html))
});
// Compile and copy Stylus
gulp.task("stylus", function(event) {
return gulp.src(sources.stylus).pipe(stylus({
use: [nib(), jeet()],
import: [
'nib',
'jeet'
],
style: "compressed"
})).pipe(gulp.dest(destinations.css));
});
// Minify and copy all JavaScript
gulp.task('scripts', function() {
gulp.src(sources.scripts)
.pipe(uglify())
.pipe(gulp.dest(destinations.js));
});
// Server
gulp.task('server', 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');
});
gulp.task('watch', function() {
livereload.listen();
gulp.watch(sources.jade, ["jade"]);
gulp.watch(sources.partials, ["jade"]);
gulp.watch(sources.stylus, ["stylus"]);
gulp.watch(sources.scripts, ["scripts"]);
});
// Define default task
gulp.task("default", ["jade", "stylus", "scripts", "server", "watch"], function(){
gulp.watch([
sources.jade,
sources.partials,
sources.stylus,
sources.scripts,
]).on('change', function(event) {
livereload.changed();
console.log('File', event.path, 'was', event.type);
console.log('LiveReload is triggered');
});
});
What happens is that I have more than 1 jade file. When I am working on - say - the 10nth in alphabetical order, and I change it, I get the livereload executed right away. The problem is that it reloads the browser tab before all jade files finish compiling and being copied to the destination, therefore the file I am currently working on is not even compiled when the refresh happens. Is there a way I can chain the reloading after a task is completed?

You have to notify livereload of changes.
In your tasks you have to add the livereload option in the end of the pipe.
For example in the jade task:
gulp.task("jade", function(event) {
return gulp.src(sources.jade)
.pipe(jade({pretty: true}))
.pipe(gulp.dest(destinations.html))
.pipe(livereload());
});
I do not try this code in your Gulpfile, but I think it works.
Regards.

I have done it. What I had to do is create a new task called "Reload", put dependencies on it and run it after each of the other tasks. Here is the new Gulpfile":
'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 livereload = require('gulp-livereload');
var sources = {
jade: "jade/**/*.jade",
partials: "partials/**/*.jade",
stylus: "styl/**/*.styl",
scripts: "js/**/*.js"
};
// Define destinations object
var destinations = {
html: "dist/",
css: "dist/css",
js: "dist/js"
};
// Compile and copy Jade
gulp.task("jade", function(event) {
return gulp.src(sources.jade)
.pipe(jade({pretty: true}))
.pipe(gulp.dest(destinations.html))
});
// Compile and copy Stylus
gulp.task("stylus", function(event) {
return gulp.src(sources.stylus).pipe(stylus({
use: [nib(), jeet()],
import: [
'nib',
'jeet'
],
style: "compressed"
})).pipe(gulp.dest(destinations.css));
});
// Minify and copy all JavaScript
gulp.task('scripts', function() {
gulp.src(sources.scripts)
.pipe(uglify())
.pipe(gulp.dest(destinations.js));
});
// Server
gulp.task('server', 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');
});
// Watch sources for change, executa tasks
gulp.task('watch', function() {
livereload.listen();
gulp.watch(sources.jade, ["jade", "refresh"]);
gulp.watch(sources.partials, ["jade", "refresh"]);
gulp.watch(sources.stylus, ["stylus", "refresh"]);
gulp.watch(sources.scripts, ["scripts", "refresh"]);
});
// Refresh task. Depends on Jade task completion
gulp.task("refresh", ["jade"], function(){
livereload.changed();
console.log('LiveReload is triggered');
});
// Define default task
gulp.task("default", ["jade", "stylus", "scripts", "server", "watch"]);

Css stylesheet has the wrong path when using gulp

I have been struggling for a while now and it is fairly frustrating to be honest.
The problem:
I created a gulpfile for my static website, and all i want to do is use browserSync, to compile sass into css and to minify the script and css files. Everything works fine, excluding one thing:
When I run "gulp" everything loads, besides de css file, which is located in "CSS/". Apparently the server thinks that the css file is ("CSS/style.css/") a folder actually.
Screenshot with the console error:
image
the css file is located in "css/style.css"
"use strict";
let paths = {
script: "js/*.js",
minifiedScript: 'script.min.js',

Gulp livereload not working in Chrome

So I am trying to set up the livereload server, however, I never get the message Live reload server listening on: <port_number> like in this video. If I change my files, the console says that the file was reloaded. I have the Chrome extension installed. What am I missing? Thanks.

I use browser-sync to reload the browser when a file has changed.
Try something like this:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
gulp.task('serve', function() {
gulp.watch("app/**/*.js").on('change', browserSync.reload);
gulp.watch("templates/**/*.html").on('change', browserSync.reload);
gulp.watch("css/**/*.css").on('change', browserSync.reload);
browserSync.init({
server: "./"
});
});
gulp.task('default', ['serve']);
I recommend your attention to the real-time browser page reload tool.

Easy to use. Works independently of the IDE. But you need the IDE to be able to auto-save files. Also works with tools like Gulp, WebPack, Grunt and others.

gulp.watch doesn't catch a new files

I have the following gulpfile
var gulp = require('gulp');
var clean = require('gulp-clean');
var rename = require('gulp-rename');
var coffee = require('gulp-coffee');
var cache = require('gulp-cached');
var path = require('path');
var dist = './Test/public/';
var assets = './Test/assets/';
var paths = {
coffee: ['./**/*.coffee']
};
var coffeeTask = function () {
console.log('coffeeTask');
return gulp.src(paths.coffee, { cwd: assets + '**' })
.pipe(cache('coffee'))
.pipe(coffee({ bare: true }))
.pipe(rename({
extname: ".coffee.js"
}))
.pipe(gulp.dest(dist));
};
gulp.task('clean', function() {
return gulp.src(dist)
.pipe(clean());
});
gulp.task('coffee', ['clean'], coffeeTask);
gulp.task('coffee-watch', coffeeTask);
gulp.task('build', ['clean', 'coffee']);
gulp.task('watch', ['build'], function() {
var w = gulp.watch(paths.coffee, ['coffee-watch']);
w.on('change', function(evt) {
console.log(evt);
});
});
gulp.task('default', ['build']);
The key point of this configuration is use the same tasks for deploy and watch processes (read "build" and "watch" tasks).
The problem is that watch task doesn't catche any new coffee files. Edited or removed coffee files are processed well. According the following issue it should works. What the reason is?
Solved by using gulp-watch module:
watch(paths.coffee, function(evt) {
gulp.start('coffee-watch');
});
The question no is how to remove in dist folder deleted file in assets folder?
