The extraction_tutorial's intro from lethain

extraction_tutorial's Introduction

This repository is an Example project using Graphene and flask-graphql to create a GraphQL server and client pair in Python.

The example server will crawl websites and extract summaries using the extraction library (mostly relying on Opengraph metadata).

You can query the server via GraphiQL by running the server and visiting http://localhost:5000.

Queries against the server look like:

{
  website(url: "https://lethain.com/migrations") {
    title
image
description
  }
}

And responses look like:

{
  "data": {
    "website": {
  "title":"Migrations: the sole scalable fix to tech debt.",
  "image":"https://lethain.com/static/blog/2018/migrations-hero.png",
  "description":"Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This post takes a look at why migrations are so important, and also how to run them effectively."
