express-html-validator
A middleware for the Express framework that automatically validates the HTML on all your Express routes, powered by html-validate. This module was built and is maintained by the Roosevelt web framework team, but it can be used independently of Roosevelt as well.
Usage
First declare express-html-validator
as a dependency in your app.
Then require the package into your application and call its constructor, passing along your Express app:
const express = require('express')
const expressValidator = require('express-html-validator')
const app = express()
const config = {}
// Generally this would be used in development mode
if (process.env.NODE_ENV === 'development') {
expressValidator(app, config)
}
// expressValidator should be called before defining routes
app.get('/', (req, res) => {
// This html response will be validated in real time as it's sent
res.sendFile(path.join(publicDir, 'index.html'))
})
Configuration
Optionally you can pass this module a set of configs:
exceptions

that when set will disable validation on the rendered HTML.- Default:
