Installation

Install via NPM.

$ npm install henning

Usage

Register the package as a server plugin to enable validation for each route that parses — parse: true — and creates a Readable stream for each file in the request payload — output: 'stream'. For every other route with a different configuration, the validation is skipped.

If the validation fails, a joi-like 400 Bad Request error is returned alongside an additional content-validation: failure response header. If everything is ok, the response will ultimately contain a content-validation: success header.

Example

const Hapi = require('hapi');
const Henning = require('henning');

try {
    const server = new Hapi.Server();

    server.route({
        options: {
            payload: {
                output: 'stream',
                parse: true
            }
            // go nuts
        }
    });

    await server.register({
        register: Henning,
        options: {
            // Allow png files only
            whitelist: ['image/png']
        }
    });

    await server.start();
}
catch (err) {
    throw err;
}
