yNews

Breaking news by ai generated defi animals.

• nice we used all the words
• collects articles and events from various sources
• summarizes what it finds using GPT

This project uses Next.js, Vercel, OpenAI, and QStash. QStash is used for http queueing, https://docs.upstash.com/qstash.

Getting started

To run this project locally you either need to be a memeber of the yNews vercel team or you can create your own vercel project and link to that. If you create your own vercel project, use the vercel dashboard to add a postgres database and add the following environment variables to all your deployments:

OPENAI_API_KEY=
QSTASH=
QSTASH_TOKEN=

Note, QStash vars are only needed if you want to automate the collectors in preview and production deployments.

Setup your local environment

yarn add vercel -g
vercel link
yarn
yarn pullenv
yarn dev

Initialize the database

CREATE TABLE articles (
  url VARCHAR(2048) NOT NULL PRIMARY KEY,
  source VARCHAR(32),
  persona VARCHAR(32),
  title VARCHAR(256),
  summary TEXT,
  tags VARCHAR(32)[],
  publish_date DATE,
  summarized BOOLEAN NOT NULL DEFAULT FALSE,
  rejected BOOLEAN NOT NULL DEFAULT FALSE,
  approved BOOLEAN NOT NULL DEFAULT FALSE,
  created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  modified_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);

Jest testing

yarn test

Endpoint testing

curl -v \
  -H "Content-type: application/json" \
  -H "key: ********" \
  -d '{ "source": "test" }' \
  'http://localhost:3000/api/collect'

curl -v \
  -H "Content-type: application/json" \
  -H "key: ********" \
  -d '{
        "source": "test",
        "articleUrl": "https://test.test.test/123"
      }' \
  'http://localhost:3000/api/summarize'

curl -v 'http://localhost:3000/api/feed'

Add new article source

1. Implement a collector at this path app/api/collect/collectors/[source name].ts
2. Implelment a summarizer at this path app/api/summarizer/summarizers/[source name].ts
3. Schedule QStash to post the collector endpoint with this body:

{
  "source": "[source name]"
}

See the test collector and summarizer for reference.

Schedule a QStash collector job

curl -v \
  -H "Authorization: Bearer ********" \
  -H "Upstash-Forward-key: ********" \
  -H "Upstash-Cron: */30 * * * *" \
  -H "Content-type: application/json" \
  -d '{ "source": "test" }' \
  'https://qstash.upstash.io/v1/publish/https://ynews-greatsword.vercel.app/api/collect'

Mannually post an article summary

curl -v \
  -H "key: ********" \
  -H "Content-type: application/json" \
  -d '{ 
        "url": "https://test.test.test/123",
        "source": "test",
