#1 solutionFeature flags for Typescript

1. Install the SDK

npm i tggl-client

2. Create the client

import { TgglClient } from 'tggl-client'
 
const client = new TgglClient('YOUR_API_KEY')

3. Start using feature flags

const flags = await client.evalContext({
  userId: 'foo',
  email: 'foo@gmail.com',
})
 
if (flags.get('my-feature', true)) {
  // ...
}

You can work with the API or choose to do local flag evaluation to evaluate millions of flags per second. The SDK also supports live configuration updates.

100% typed

Types are automatically pulled from the API and are available in your IDE. Nor more guessing what the return type of a flag is, all typos are picked-up by your IDE and CI build process.
