- ✅ Tested across multiple elections.
- 📆 Simulates your own election night tests.
Install
npm install election-tonight-client
Quickstart
Initialise the client.
import { ElectionTonightClient } from 'election-tonight-client';
// ElectionTonight API key
const API_KEY = 'SECRET';
// ElectionTonight event ID
const EVENT_ID = '20221108';
const client = new ElectionTonightClient(API_KEY, EVENT_ID);
Connect to your PostgreSQL database, using Postgres.js.
const databaseUrl = 'postgresql://localhost:5432/yourdb';
client.connect(databaseUrl);
Setup the event with all its metadata.
await client.setupEvent();
Get all election data in a "sweep" ...
await client.getCountyVotes();
await client.getCalls();
await client.getEditorialTurnout();
await client.getTotalExpectedVote();
await client.getMessages();
... or get just the latest in a "stream."
let updatedEntities = await client.getStreamedCountyVotes();
// Now, do something with the updated entites -- states,
// offices, etc. -- returned from the stream.
for (const updatedEntity of updatedEntites.updated) {
console.log(`New votes for state: ${updatedEntity.state}`);
}
updatedEntities = await client.getStreamedCalls();
updatedEntities = await client.getStreamedEditorialTurnout();
updatedEntities = await client.getStreamedTotalExpectedVote();
updatedEntities = await client.getStreamedMessages();
Filter requests to only get the county vote data you want.
client.filter({
states: ['TX', 'KS', 'MO'],
summary: true,
});
await client.getCountyVotes();
After you've gotten election data from the API, use Drizzle queries to retrieve records from your database.
const states = await client.db.query.state.findMany();
Close the PostgreSQL connection when you're done.
await client.disconnect();

Testing
Setup
Export a DATABASE_URL
environment variable or use the built-in ephemeral PostgreSQL testcontainer.
If using testcontainers, you must have a Docker client installed, e.g., Docker Desktop.
Running tests
npm run test
Run specific tests by passing a substring or regular expression to the --grep
filter:
npm run test -- --grep 'your-substring'
