    ExpressJs middleware for rendering PWA to bots using Puppeteer

    This is a middleware for ExpressJs that uses Puppeter for render the page requested by "indexing" bots (and not).

    This is a fork of the rendertron-middleware but using Puppeter instead of Rendertron, without needing another server to render the app. I have made some changes for my personal use (like removing the inject ShadyDOM option).

    Install

    $ yarn add pupperender
    

    Usage

    const express = require('express');
    const pupperender = require('pupperender');
    
    const app = express();
    
    app.use(pupperender.makeMiddleware({}));
    
    app.use(express.static('files'));
    app.listen(8080);

    Configuration

    Like rendertron-middleware I decided to expose a makeMiddleware function that takes a configuration object with the following properties:

    Property Default Description
    userAgentPattern A set of known bots that benefit from pre-rendering. Full list. RegExp for matching requests by User-Agent header.
    excludeUrlPattern A set of known static file extensions. Full list. RegExp for excluding requests by the path component of the URL.
    timeout 11000 Millisecond timeout for waiting the page to load. Used by Puppeter. See also the Puppeter waitFor()
    debug false DEBUG flag to show some logs
    useCache false If the puppeterized content should be cached to speed up subsequent requests.
    cacheTTL 3600 Seconds until cached content is disregarded and puppeterized again. Only considered when useCache is true.
