All Running on koa, will soon move to react-router ^1.0 Built on top of isomorphic flux boilerplate, by iam4x
Create mysql database, import db from /db/dump.sql
Go to /server/db-sample.js and replace credentials with yours.
`!without db it wont work`
Use with iojs^1.8.0 or nodejs^0.12.0, clone the repo, npm install and npm run dev.
Learn React (react-prime-draft), learn Flux and Alt (alt guide).
Wrap you async actions into promises, send them to altResolver with altResolver.resolve(xxx) for async server side rendering (see app/actions/users.js:31).
Build for production with npm run build, don't forget to run the tests before npm test.
Koa will be our server for the server side rendering, we use alt for our Flux architecture and react-router for routing in our app.
With iso as helper we can populate alt flux stores before the first rendering and have a complete async isomorphic React application.
Run this boilerplate, you will see the server is fetching some fake users and will populate the UserStore with this data. Koa will render the first markup, serve the JavaScript and then it will entirely run on the client.
We use alt instance as Flux implementation.
We need to use instances for isomorphic applications, to have a unique store/actions per requests on the server.
On the client, Flux is initialized in app/main.js and sent to our first React Component via props (this.props.flux). Everytime you want to uses stores or actions in a component you need to give it access through props.
On the server, it's similar but Flux is initialized in server/router.jsx. The instance is sent to alt-resolver for rendering components with the correct props.
Learn more about alt instances in the alt documentation.
We use react-intl for internationalization, it uses browser implementation of Intl. For older browser and for node, we load the polyfill.
- Support localized strings (see data/en.js)
- Support localized dates, times and currencies.
Lang files and Intl polyfill are compiled into webpack chunks, for lazy-loading depending the locale of the user.
If user changes locale, it is saved into a cookie _lang and used by the server to know the locale of rendering. If there's no _lang cookie, server will rely on Accept-Language request header. Server will set <html lang='x'> on rendering.
Thank's to gpbl/react-locale-hot-switch for the implementation example!
Alt-resolver is the magic thing about the boilerplate, it will be our tool for resolving promises (data-fetching) before server side rendering.
Wrap data-fetching requests from actions into promises and send them to altResolver like:
fetch() {
// cache this because inside of xhr it will refer to xhr instance
var prv = this;
//declare a promise
const promise = (resolve) => {
// trigger start loading action ( show spinner )
this.alt.getActions('requests').start();
// declare new xhr and handle response onreadystatechange (it will happen after we .open)
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
// if we have 200 OK status on response, lets parse it and go further with it
var _json = JSON.parse(xhr.responseText);
debug('dev')(_json);
prv.actions.fetchSuccess(_json);
prv.alt.getActions('requests').success();
// return a resolve()
return resolve();
}
else {
debug('dev')('XHR failed, msg: ', xhr.responseText);
}
}
};
// open and send a request
xhr.open('GET', 'http://localhost:3000/api/users');
xhr.send();
};
// pass promise to alt, it will resolve it for us
this.alt.resolve(promise);
}
Call the fetch action from component in the componentWillMount method:
static propTypes: {
flux: React.PropTypes.object.isRequired
}
componentWillMount() {
const usersActions = this.props.flux.getActions('users');
return usersActions.fetch();
}
On browser side, the rendering won't be stopped and will resolve the promise instantly.
On server side, altResolver.render will fire a first render to collect all the promises needed for a complete rendering. It will then resolve them, and try to re-render the application for a complete markup.
Open app/actions/users.js, app/utils/alt-resolver.js, app/stores/users.js for more information about data-fetching.
On client with webpack, you can directly require() images for your images DOM element like:
<img src={require('images/logo.png')} />
Webpack will load them through the url-loader and if it's too big it will sent through file-loader for minification/compilation. The results is an image with a new filename for cache busting.
But on node, require() an image will just throw an exception. There's an util for loading image on server side to achieve this:
import imageResolver from 'utils/image-resolver'
let image;
// On browser just require() the image as usual
if (process.env.BROWSER) {
image = require('images/logo.png');
}
else {
image = imageResolver('images/logo.png');
}
...
render () {
return (
<img src={image} />
);
}
...
The utils/image-resolver with match the original image name with the compiled one.
Voilà! You can require() images on server side too.
I recommend to use io.js to take advantages of ES6 without --harmony flag on NodeJS.
It's super easy to do with nvm:
$ nvm install iojs$ nvm use iojs$ nvm alias default iojs(to makenodedefault toiojs)
But it works well with nodejs^0.12.0 as well :)
After that, you will just need to clone the repo and install dependancies:
$ git clone -o upstream https://github.com/iam4x/isomorphic-flux-boilerplate.git app$ cd app && npm install
(Don't forget to add your remote origin: $ git remote origin [email protected]:xxx/xxx.git)
$ npm run dev
Open your browser to http://localhost:3002 and you will see the magic happens! Try to disable JavaScript in your browser, you will still be able to navigate between pages of the application. Enjoy the power of isomorphic applications!
(Note: ports 3000-3002 are needed, you can change this with $ PORT=3050 npm run dev it will run on 3050-3052)
$ npm testwill run the tests once$ ./node_modules/.bin/karma startwill watch for changes and run the tests on change
Just run $ npm run build, it will produce these tasks:
- Run tests from
test/spec/**/*.jsx - Concat & minify styles to
/dist/app-[hash].css - Concat & minify scripts to
/dist/js/app-[hash].js
Build the project first:
$ npm run build
Then start the koa server:
$ NODE_ENV=production node server/index.js(iojs)$ NODE_ENV=production node --harmony server/index.js(nodejs 0.12.x)
You can also use processes.json to run the application with PM2 Monitor on your production server (customize it for your use):
$ pm2 start processes.json
