How create flux architecture in asp.net using reactjs.net ?
I will have several files. Jsx, how will I manage to be all rendenizador by the server?
In this example => Link, it creates using asp.net but not render with server
I am currently working on a feature as a test bed for reactjs + flux in our .net application. Here is how it is set up.
We use nodejs as a package manager. we use NodeJs Visual Studio Tools to get the nodejs interactive window in VS and to be able to create NodeJs projects. http://nodejstools.codeplex.com/
Gulp task calls browserify to search through the the root jsx and find all dependencies. Gulp also calls the reactify library is used to transform the jsx files. The concatenated .js file is put on in a directory in our mvc website.
Gulp task copies all relevant js files to the mvc.net project as well.
When developing we use the Visual Studio Task Runner extension to run a Gulp task that watches for changes so we don't have to "keep building" while developing. It uses the "watchify" library.
We use Jest for testing - although we had an issue with NodeJs and jest playing nice in the newest version of NodeJs, so we had to down grade to 0.10.36.
we use TeamCity to run the Gulp task before building our solution (have a test setup, but haven't added it to my new feature yet).
Gulp does most of the magic. Here is a copy of our Gulp file (it is messy, but I am still learning). Many of the tasks are to watch css js and jsx files, but I hope this helps.
var gulp = require('gulp');
var source = require('vinyl-source-stream');
var browserify = require('browserify');
var watchify = require('watchify');
var reactify = require('reactify');
var concat = require('gulp-concat');
var buffer = require('vinyl-buffer');
var uglify = require('gulp-uglify');
var createbundler = function () {
var bundler = browserify({
entries: ['./app/js/VaeApp.jsx'], // Only need the root js file, browserify finds the dependencies
transform: [reactify], // We want to convert JSX to normal javascript
debug: false, // include sourcemapping for minified scripts?
cache: {}, packageCache: {}, fullPaths: true // Requirement of watchify
});
return bundler;
}
gulp.task('js', function () {
var bundler = createbundler();
bundler.bundle()
.pipe(source('bundle.js'))
.pipe(buffer())// <----- convert from streaming to buffered vinyl file object
.pipe(uglify())
// Create the initial bundle when starting the task
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/js'));
});
gulp.task('js-shim-sham', function () {
gulp.src('./node_modules/es5-shim/es5-*.min.js')
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/js'));
console.log("updated shim-sham");
});
gulp.task('js-dev', function () {
var watcher = watchify(createbundler());
return watcher
.on('update', function () { // When any files update
var updateStart = Date.now();
console.log('Updating!');
watcher.bundle().pipe(source('bundle.js'))
.pipe(buffer())// <----- convert from streaming to buffered vinyl file object
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/js'));
console.log('Updated!', (Date.now() - updateStart) + 'ms');
})
.bundle()
.pipe(source('bundle.js'))
.pipe(buffer())// <----- convert from streaming to buffered vinyl file object
// .pipe(uglify())
// Create the initial bundle when starting the task
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/js'));
});
var runcss = function () {
var updateStart = Date.now();
gulp.src('./app/css/document/*.css')
.pipe(concat('main.css'))
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/css'));
console.log('Updated!', (Date.now() - updateStart) + 'ms');
};
var runimages = function () {
var updateStart = Date.now();
gulp.src('./app/img/*.*')
.pipe(gulp.dest('../Mvc.Web/Scripts/Flux/img'));
console.log('Updated!', (Date.now() - updateStart) + 'ms');
};
gulp.task('styles', function () {
runcss();
runimages();
});
gulp.task('styles-dev', function () {
runcss();
gulp.watch('./app/css/document/*.css', runcss);
runimages();
gulp.watch('./app/img/*.*', runimages);
});
// Just running the two tasks
gulp.task('build-dev', ['js-dev', 'styles-dev', 'js-shim-sham']);
// Just running the two tasks
gulp.task('build', ['js', 'styles', 'js-shim']);
Check out react-dot-not.
It uses webpack/gulp with ASP.MVC. it supports redux/flux, supports client side routing with react-router, with an F5 at any time to re-render the same page from the server.

I made a gulp.js file that is meant to be observing my changes and rebuilding so that my react code can update after the scss gets converted to css with each change. Here's what I have:
'use strict';
//dependencies
var gulp = require('gulp');
var sass = require('gulp-sass');
var minifyCSS = require('gulp-clean-css');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var changed = require('gulp-changed');
//////////////
// - SCSS/CSS
//////////////
var SCSS_SRC = './src/assets/scss/**/*.scss';
var SCSS_DEST = './src/assets/css';
// Compile SCSS
gulp.task('compile_scss', function(){
gulp.src(SCSS_SRC)
.pipe(sass().on('error', sass.logError))
.pipe(minifyCSS())
.pipe(rename({ suffix: '.min'}))
.pipe(changed(SCSS_DEST))
.pipe(gulp.dest(SCSS_DEST));
});
//detect changes in SCSS
gulp.task('watch_scss', function(){
gulp.watch(SCSS_SRC, gulp.series('compile_scss'));
});
//Run tasks
gulp.task('default', gulp.series(['watch_scss'], function(){
}));
This is the first time I do this but from what I can tell it is correct. There's no error being thrown and it works sometimes. However, when I make 2 changes to my default.scss file, the 1st one gets converted to css but for the second one I need kill the task and run gulp again. What might I be missing?
My project's setup uses a combination of python's Flask on the backend which serves a fairly simple javascript React webpage using gulp.
Whether I'm debugging frontend code through Chrome or Firefox, I have to do a hard refresh multiple times before the changes make it to the browser. I see the gulp console log Finished 'transform' after N ms after each save, which leads me to believe it's the browsers fault.
I am not a front end engineer so I'm wondering what more experienced devs use. Hitting Cmd+Shift+R 5-20 times after each save is a little mind bogglingly inefficient.
current gulpfile.js:
'use strict';
var gulp = require('gulp'),
browserify = require('browserify'),
size = require('gulp-size'),
del = require('del'),
babelify = require('babelify'),
source = require('vinyl-source-stream'),
gutil = require('gulp-util');
var compiled_dir = './static/scripts/jsc';
var js_dir = './static/scripts/js';
function handle_error(err) {
gutil.log(err.message);
gutil.beep();
return process.exit(2);
}
gulp.task('transform', function () {
browserify({ entries: js_dir + '/main.js', debug: true })
.transform(babelify)
.bundle()
.on('error', handle_error)
.pipe(source('main.js'))
.pipe(gulp.dest(compiled_dir));
browserify({ entries: js_dir + '/userMgmt.js', debug: true })
.transform(babelify)
.bundle()
.on('error', handle_error)
.pipe(source('userMgmt.js'))
.pipe(gulp.dest(compiled_dir));
});
gulp.task('clean', function (cb) {
del([compiled_dir], cb);
});
gulp.task('default', ['clean'], function () {
gulp.start('transform');
gulp.watch(js_dir + "/*", ['transform']);
});
Method 1: Use this gulp-cache package to disable cache in development mode.
This will work:
var gulp = require('gulp');
var usemin = require('gulp-usemin');
var cache = require('gulp-cache');
gulp.task('default', function () {
return gulp.src('src/index.html')
.pipe(gulp.task('clear', function (done) {
return cache.clearAll(done);
});)
.pipe(usemin({
js: []
}))
.pipe(gulp.dest('dist'));
});
If you don't know how to use it, please update your question with gulp config file, I will configure you that.
Method 2: Configure your watcher.
$ npm install browser-sync --save-dev
var browserSync = require('browser-sync').create();
gulp.watch(['./**/*.{scss,css,html,py,js}'], ['clearCache', browserSync.reload]);
gulp.task('clearCache', function (done) {
return cache.clearAll(done);
});
I have been working on an Angular JS based application. I have written a set of gulp commands to uglify/remove comments from JS code. When I run the web application and monitor the network traffic, I noticed that minified(uglified) 'all.js' file consumes quite a lot of time to be loaded (please forget about the caching).
I believe that splitting the all.js file (before or after processing) in to several pieces (let's say four pieces) will improve the application loading time. Please mention if you think there is/are better way(s).
Still I am struggling to find a way to get an approach to above mentioned method under #1. Still no luck :-( Please advice me.
Gulpfile
// include plug-ins

When I run gulp I get an "updating!" and "updated!" log after saving main.js but there's no bundle ever built
gulpfile.js:
var watchify = require('watchify');
var reactify = require('reactify');
var concat = require('gulp-concat');
var util = require('gulp-util');
gulp.task('browserify', function() {
var bundler = browserify({
entries: ['./dist/main.js'], // Only need initial file, browserify finds the deps
transform: [reactify], // We want to convert JSX to normal javascript
debug: true, // Gives us sourcemapping
cache: {}, packageCache: {}, fullPaths: true // Requirement of watchify
});
var watcher = watchify(bundler);
return watcher
.on('update', function () { // When any files update
var updateStart = Date.now();
console.log('Updating!');
watcher.bundle() // Create new bundle that uses the cache for high performance
.pipe(source('main.js'))
.on('error', util.log)
// This is where you add uglifying etc.
.pipe(gulp.dest('/build/'));
console.log('Updated!', (Date.now() - updateStart) + 'ms');
})
.on('error', util.log)
.bundle() // Create the initial bundle when starting the task
.pipe(source('main.js'))
.pipe(gulp.dest('/build/'))
.on('error', util.log);
});
// I added this so that you see how to run two watch tasks
gulp.task('css', function () {
gulp.watch('styles/**/*.css', function () {
return gulp.src('styles/**/*.css')
.pipe(concat('main.css'))
.pipe(gulp.dest('build/'));
});
});
// Just running the two tasks
gulp.task('default', ['browserify', 'css']);
My file structure is
/build
/dist
-index.html
-main.js
/node_modules
/styles
gulpfile.js
I am not finding any errors and I am completely lost at this point. I've tried changing directories around and reloading everything but nothing works.
Update lines that contain gulp.dest('/build/') to gulp.dest(__dirname + '/build/'). Currently your file located at drive_root_dir/build/main.js
I'm trying to figure out how to test backbone using jsdom and nodeunit as the testing framework.
I've got the error: "Error: Calling node's require("text") failed with error: Error: Cannot find module 'text'"
What means, that the context was not able to load requirejs-text plugin.
I've created the DOM context witn:
var assert = require('assert');
var fs = require('fs');
var index_html = fs.readFileSync(__dirname + '/../static/index.html', 'utf-8');
var requirejs = require('requirejs');
var jsdom = require('jsdom');
// require('amdefine/intercept');
var jQuery = require('jquery');
On the test setUp, on trying to open up the backbone view:
exports.setUp = function(callback){
var document = jsdom.jsdom(index_html);
var window = document.parentWindow;
jsdom.getVirtualConsole(window).sendTo(console);
requirejs.config({
baseUrl: __dirname + '/',
packages: [{
name: 'text',
location: '../node_modules/requirejs-text/text.js ',
main: 'text.js'
},
],
});
requirejs([__dirname + '/../lib/views/stackoverflow.js'], function(bb){
callback();
});
};
The exception is raised on before the callback is called. The view that I'm using is just a regular view using requirejs-text to load the template. I've also created a GitHub Repository just to better explain the issue. Just clone it, enter the project dir and type make. It should reproduce all the steps that I've did.
Thanks in advance!
