Readability JS server

Mozilla's Readability.js as a service

What

This project packages Mozilla's Readability JS as an HTTP service that can be deployed via Docker anywhere.

How to query

There's only one endpoint, which consumes and delivers json. You send in a URL to some page you want content extracted, you get back a json payload echoing the URL and containing the stripped out content.

~ curl -XPOST http://readability-js-server:3000/ \
    -H "Content-Type: application/json" \
    -d'{"url": "https://en.wikipedia.org/wiki/Firefox"}'

To which you will receive:

HTTP/1.1 200 OK
X-Powered-By: Express
Content-Type: application/json; charset=utf-8
{
   "url": "https://en.wikipedia.org/wiki/Firefox",
   "content": "<div id=\"readability-page-1\" class=\"page\"><div id=\"mw-content-text\" lang=\"en\" dir=\"ltr\"><div>\n\n\n\n<table><caption>Firefox</caption><tbody><tr><td colspan=\"2\"><a href=\"/wiki/File:Firefox_Logo,_2017.svg\"><img alt=\"Firefox Logo, 2017.svg\" src=\"//upload.wikimedia.org/wikipedia/commons/thumb/6/67/Firefox [...]"
   "excerpt": "Firefox 65 (Quantum) running on Arch Linux with KDE Plasma 5",
}

How to run

Docker

The container image lives at phpdockerio/readability-js-server. At the moment, it takes no configuration for anything, although this might change if and when the use case arises.

Versioning

We tag each image as latest, x.x.x, x.x and x. Since Semver is in use, you can peg to, say, phpdockerio/readability-js-server:1 with the confidence that no breaking changes will come to ruin your day. You can also peg to phpdockerio/readability-js-server:1.x if there's a specific minor version that introduces a new feature you need.

Example

You'll probably be using this if you're deploying the service somewhere. Simply run the equivalent to

~ docker run -p3000:3000 phpdockerio/readability-js-server

Locally

You'll need node >= 10 and yarn.

Once you clone the repo:

~ yarn install
~ yarn start

Notes

No configuration required. This might change if the need arises.
The app requires node 10. There's nothing specific about node 10 we're using, but yarn.lock was created with it so some of the dependencies might require it. If you want to run this on say AWS lambda and node 8, it might work if you nuke yarn.lock and re-create it with that node version.
The docker image runs via pm2 and node 10 with 5 processes. I might make this configurable if there's demand.
