I know that this can be a very stupid question, but I can't find matches with other posts on stackoverflow...
So: Can I modify a file of an external module , just save the file and do something that my app can listen?
At the moment, i'm trying ti change some scss style at the ng2-datepicker module (inside node_modules folder), but if I save and the launch ng serve, changes will not affect my project.
I know it's a simple problem, but i don't know the background architecture of an Angular2 project.
Thanks in advance.
(ps I've seen that i can fork the git and then do something like npm install.
Very interesting, but i also want to know how to have the same result in local)
If you are using gulp file you can tell the changed lib file path to copy to build folder check gulp.task('copy-libs') in code below git repo for angular2-tour-of-heroes using gulp
const gulp = require('gulp');
const del = require('del');
const typescript = require('gulp-typescript');
const tscConfig = require('./tsconfig.json');
const sourcemaps = require('gulp-sourcemaps');
const tslint = require('gulp-tslint');
const browserSync = require('browser-sync');
const reload = browserSync.reload;
const tsconfig = require('tsconfig-glob');
// clean the contents of the distribution directory
gulp.task('clean', function () {
return del('dist/**/*');
});
// copy static assets - i.e. non TypeScript compiled source
gulp.task('copy:assets', ['clean'], function() {
return gulp.src(['app/**/*', 'index.html', 'styles.css', '!app/**/*.ts'], { base : './' })
.pipe(gulp.dest('dist'))
});
// copy dependencies
gulp.task('copy:libs', ['clean'], function() {
return gulp.src([

'node_modules/immutable/dist/immutable.js'
'yourpath/changedFileName.js'
])
.pipe(gulp.dest('dist/lib'))
});
// linting
gulp.task('tslint', function() {
return gulp.src('app/**/*.ts')
.pipe(tslint())
.pipe(tslint.report('verbose'));
});

});
// update the tsconfig files based on the glob pattern
gulp.task('tsconfig-glob', function () {
return tsconfig({
configPath: '.',

});
});
// Run browsersync for development
gulp.task('serve', ['build'], function() {

I'm a tad lost on why my gulp tasks aren't running when a file is changed. In the console, it's detected the change but it's not actually re-running the tasks. Fairly new to gulp, so would love a little help.
const gulp = require('gulp');

exports.style = style; // Expose the style task

Was the bugged line about twig and templates. Such a pain. Removing this fixed the issue.
I am trying to create a gulpfile.js to compile scss to css and JS components to a main JS file. But it's not working properly.
The issues i am facing, when I run the command gulp:
It doesn't compile JS components to a main JS file.
It compiles SCSS but when i save any file, the git-bash terminal executing files infinitely, here is the screenshot:
Here is my gulpfile.js:
"use strict";
const source = 'assets/';
// Load Modules
const { src, dest, watch, series } = require('gulp');
const sass = require('gulp-sass')(require('sass'));
const postcss = require('gulp-postcss');
const cssnano = require('cssnano');
const terser = require('gulp-terser');
const browsersync = require('browser-sync').create();
// Scss Task
function scssTask() {
return src(`${source}/scss/zaincss.scss`)
.pipe(sass())
.pipe(postcss([cssnano()]))
.pipe(dest(`${source}/css`));
}
// Javascript Task
function jsTask() {
return src(`${source}/js/scripts/*.js`)
.pipe(terser())
.pipe(dest(`${source}/js/scripts/`));
}
// BrowserSync Tasks
function browserSyncServe(done) {
browsersync.init({
server: {
baseDir: '.'
},
injectChanges: true
});
done()
}
function browserSyncReload(done) {
browsersync.reload();
done();
}
// Watch Task
function watchTask() {
watch('*.html', browserSyncReload);
watch(['assets/scss/**/*.scss', 'assets/js/**/*.js'], series(scssTask, jsTask, browserSyncReload));
}
// Default Gulp Task
exports.default = series(
scssTask, jsTask, browserSyncServe, watchTask
);
I have googled a lot, but i am stuck. Please help me.
Part of the problem is you are watching the same directory that you are storing your js files in:
// Javascript Task
function jsTask() {
return src(`${source}/js/scripts/*.js`)
.pipe(terser())
.pipe(dest(`${source}/js/scripts/`));
}
So you send the files to ${source}/js/scripts/ but you are watching that location in your watch task: 'assets/js/**/*.js'. So any change in that location starts the process all over again.
Store you minified js files someplace else than the same directory you are watching for changes.
I have my gulpfile:
var gulp = require('gulp');
var sass = require('gulp-sass');
var watch = require('gulp-watch');
var sourcemaps = require('gulp-sourcemaps');
var fileinclude = require('gulp-file-include');
var browserify = require('browserify');
var rename = require('gulp-rename');
var streamify = require('gulp-streamify'); // required for uglify
var uglify = require('gulp-uglify'); // minify JS
var source = require('vinyl-source-stream'); // required to dest() for browserify
var browserSync = require('browser-sync').create();
var localSettings = require('./gulp/localConfig.js');
gulp.task('sass', function () {
return gulp.src('./assets/sass/main.scss')
.pipe(sourcemaps.init())
.pipe(sass().on('error', sass.logError)) // .on('error', sass.logError) prevents gulp from crashing when saving a typo or syntax error
.pipe(sourcemaps.write())
.pipe(gulp.dest('./assets/sass'))
.pipe(browserSync.stream()); // causes injection of styles on save
});
gulp.task('compileHTML', function() {
return gulp.src(['static/src/*.html'])
.pipe(fileinclude({
prefix: '##',
basepath: '#root'
}))
.pipe(gulp.dest('./static/compiled'))
.pipe(browserSync.stream()); // causes injection of html changes on save
});
// Static Server for browsersync
gulp.task('sync', ['sass'], function() {
browserSync.init({
startPath: "static/compiled/index.html",
open: localSettings.openBrowserSyncServerOnBuild,
server: {
baseDir: "./",
}
});
});
gulp.task('watch', function() {
gulp.watch('./assets/sass/**/*.scss', ['sass']);
gulp.watch(['./static/src/**/*.html', '!partials', '!components'], ['compileHTML']);
gulp.watch('./assets/js/**/*.js', ['javascript']);
});
gulp.task('javascript', function() {
var bundleStream = browserify('./assets/js/main.js').bundle();
bundleStream
.pipe(source('main.js'))
.pipe(rename('bundle.js'))
.pipe(gulp.dest('./assets/js/'))
.pipe(browserSync.stream());
})
// Default Task
gulp.task('default', ['compileHTML', 'javascript', 'sass', 'watch', 'sync']);
Mostly everything with my build works great, however I am having one issue with my compileHTML task. When any modifications are made to my html, it is compiled and injected into the page with BrowserSync. The problem is that BrowserSync is injecting the markup into the page AFTER it reloads, so that I have to manually refresh or save the file again.
Although I am doing the exact same thing with my SASS task, I have no problems with that task. Why do my styles inject into the page before the reload, but the HTML does not?
Just for testing, I tried adding a setTimout surrounding the BrowserSync injection, but it did not affect the timing of the injection other than adding a delay.
I would try to follow the example at gulp-reload docs. Their example is:
// create a task that ensures the `js` task is complete before
// reloading browsers
gulp.task('js-watch', ['js'], function (done) {
browserSync.reload();
done();
});
So you try :
gulp.watch(['./static/src/**/*.html', '!partials', '!components'], ['compileHTML'],
function (done) {
browserSync.reload();
done();
});
And remove the pipe browserSync.stream() in your 'complieHTML' task.
[I might first try as a very simple attempt changing from stream() to reload() in that task before the changes above.]
I'm attempting to use browser-sync with Gulp 4, but bs is not preserving state, and instead does a full refresh. This is not very useful. It seems bs no longer supports true injection. I filed an issue on GH if you want to contribute.
Here is the pertinent code:
// styles:dev task
gulp.task('styles:dev', function() {
return gulp.src(config.src)
.pipe(sourcemaps.init())
.pipe(postcss(config.postcss.dev))
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest(config.dest.dev))
.pipe(browserSync.stream());
});
// browserSync task
gulp.task('browserSync', function(cb) {
browserSync.init(config, cb);
});
// Watch task:
gulp.task('watch:styles', function() {
return gulp.watch(config.paths.css,
gulp.series('styles:dev'));
});
gulp.task('watch', gulp.parallel('watch:styles'));
// default task
gulp.task('default',
gulp.series('clean:dev',
gulp.parallel('copy:dev', 'styles:dev'), 'browserSync', 'watch')
);
Thanks in advance.
Fixed. Here's where I went wrong:
The browser-sync constructor takes an options object, which can include a files array. Most of the tutorials I've read, including the gulpfile for Google's very own Web Starter Kit, do not include this. As it turns out, this is required for style injection to preserve state.
Furthermore, do not pass .stream() or .reload() as the final pipe in your styles task. It is not needed, and will short circuit style injection, forcing a full refresh.
Finally, the browserSync process must not be terminated, and watch and browserSync tasks must execute in parallel in order for live style injection to take place.
Hope this helps anybody facing this issue.
I also closed the corresponding github issue, and posted my gulpfile
Almost 3 years later Gulp 4 now looks a little bit different, see https://gulpjs.com/docs/en/getting-started/creating-tasks

Goal
I'm updating my old gulpfile.js, which used to be mainly for compiling my Sass into CSS, but now I'm trying to get Gulp to do the following:
Sync browser, whip up localhost server - DONE
Compile Sass => CSS - DONE
Show any JavaScript errors with JSHint - DONE
Compile ES6 => ES6 with Babel (WORKING ON)
Minify all assets (WORKING ON)
Show project file size - DONE
Deploy index.html, style.css and images to S3 (WORKING ON)
Watch files, reload browser when .scss or .html changes - DONE
Problem
Trying to minify my Javascript and also create a scripts.min.js
file, it keeps adding the suffix min to every new minified JavaScript
file.

Hi i can't solve all your problems but I had also a similar issue with the babel and ES6 fat arrow functions (using babelify and browserify). To solve the problem try to pass:
stage: 0
to your babel.js gulp plugin. If error will still occurs then try to pass also:
experimental: true
For more information please have a look "experimental" section on babel.js site.
