Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
react-collider
Advanced tools
Express middleware for isomorphic Express + React apps. Also usable for any NodeJs app without Express.
Check out the example
folder for a working example, including data-fetching from the Dailymotion API.
$ npm install --save react-collider
Simply add the server middleware in your express app, giving your routes as argument.
var express = require('express'),
app = express(),
port = process.env.PORT || 3000,
collider = require('react-collider/server'),
routes = require('./routing')
app.use(collider(routes))
app.listen(port, function() {
console.log('Listening on 127.0.0.1:' + port)
})
You can have informations in a log file:
// logs to react-collider.log
app.use(collider(routes, {log: true}))
// logs to a custom file path
app.use(collider(routes, {log: path.join(__dirname, 'server.log')}))
Similar: call the client module with your routes.
var collider = require('react-collider/client'),
routes = require('./routing')
collider(routes)
If your component must fetch some data before being rendered, use a fetchData
static method. It must return a promise.
Example of a simple component:
var Home = React.createClass({
displayName: 'Home',
statics: {
fetchData: function() {
// returns a promise
return getHomeData()
}
},
render: function() {
var videos = getVideoList()
return (
<div>
<h1>Homepage</h1>
{videos}
</div>
)
}
})
When your component includes another component which needs data too, define a getDependencies
static method to return an array of components:
var Sidebar = require('./sidebar'),
Footer = require('./footer')
var Home = React.createClass({
displayName: 'Home',
statics: {
getDependencies: function() {
return [Sidebar, Footer]
}
},
render: function() {
return (
<div>
<Sidebar data={this.props.data.Sidebar} />
<div>
<h1>Homepage</h1>
</div>
<Footer data={this.props.data.Footer} />
</div>
)
}
})
Important: If you're not using es6 to write your components, be sure to define the displayName
of your components. This is necessary for the module to correctly return the data.
The dataProvider
module allows data fetching from a url or from the initial data fetched server-side.
###dataProvider(component, url, options)
component
React component. Used to store and retrieve the data in a local variable to prevent useless calls on the first page load, and for caching.url
Url to calloptions
Object. Available options:
once
: Removes the data from the local variable after use. This means the next time you call the same data it will fetch them remotely. Default to false.forceFetch
: Fetches the data remotely even if the data are available locally. Default to false.set
: Sets the data locally after fetching them remotely. The next time you need them they will be taken locally (unless you use the forceFetch
option). Default to false.var provider = require('react-collider/dataProvider')
var Home = React.createClass({
displayName: 'Home',
statics: {
fetchData: function() {
return provider(this, 'https://api.dailymotion.com/videos?fields=id,title', {once: true})
}
}
})
If your servers are down and you can't pre-render the pages server-side, your app will still work client side (assuming your API is okay). All you need is to send a basic html file with your app bundled. Check out the example
folder for an example.
You can use react-collider wihtout express. You can simply use it to get the React component to render and the data to use:
var collider = require('react-collider'),
routes = require('./routing')
var url = '/video'
// simply provide your routes and the url
collider(routes, url, function(Handler, data) {
var page = React.renderToString(React.createElement(Handler, {data: data}))
})
