Fomo plugin

Use Fomo through Corsair: one client, typed API calls. Fomo authenticates API requests using an Auth Token passed in the Authorization: Token <token> header. To find your token, log into Fomo, navigate to Settings > Site, and copy the Auth Token located near the bottom of the page. Each website connected to Fomo has its own unique application token. What you get:

14 typed API operations

Setup

Install

npm install corsair @corsair-dev/fomo better-sqlite3
npm install --save-dev @types/better-sqlite3

yarn add corsair @corsair-dev/fomo better-sqlite3
yarn add --dev @types/better-sqlite3

pnpm install corsair @corsair-dev/fomo better-sqlite3
pnpm install --save-dev @types/better-sqlite3

bun add corsair @corsair-dev/fomo better-sqlite3
bun add --dev @types/better-sqlite3

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { fomo } from '@corsair-dev/fomo';

export const corsair = createCorsair({
	plugins: [
		fomo(),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

With multiTenancy: true, scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

API Key (Recommended)

Store the Fomo API key before the first call: pnpm corsair setup --plugin=fomo --tenant=acme api_key=<your-key> (leave out --tenant without multiTenancy), or pass it as key in the plugin options. With Hub, each tenant enters their own key on the connect page. See API key auth.

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'fomo',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

List recent notification events

const tenant = corsair.withTenant('acme');
await tenant.fomo.api.events.list({ per: 10, page: 1 });

Create a new notification event

const tenant = corsair.withTenant('acme');
await tenant.fomo.api.events.create({
	event_type_id: 123,
	first_name: 'John',
	city: 'New York',
	title: 'Annual Subscription',
	url: 'https://example.com/product',
});

See the full list on the API page.
