GrowthBook 2.0 — Developer Day!

GrowthBook 2.0 is here! Learn about the developer-focused improvements in 2.0, including Typesafe SDK, REST API, and more!

GrowthBook 2.0 is finally here, and this new version is so packed full of feature announcements that we had to split it up over 3 days. Today, we’re focusing on class developer experience.

Typesafe SDK

GrowthBook is pleased to offer the first-ever fully typesafe feature flag SDK for Typescript. Now you can detect typos and bugs in your feature flag checks during compile time. To make this possible, we built a GrowthBook CLI that can auto-generate type definitions based on features defined in your GrowthBook account. You can read more about this feature and get detailed instructions for setting it up on our engineering blog — https://blog.growthbook.io/fully-typesafe-sdk

Instant Feature Releases

After the success of our self-hosted GrowthBook Proxy release in version 1.9, we’re excited to bring the same benefits to our Pro and Enterprise customers on GrowthBook Cloud. Over the next several weeks, we will enable instant feature rollouts on these accounts. When enabled, feature changes you make in the GrowthBook UI will be released to all of your users in under a second. Read more about this feature and how we’re scaling it to billions of feature requests on our blog — https://blog.growthbook.io/faster-feature-releases-on-growthbook-cloud

REST API

We have been hard at work expanding our REST API, adding over 20 new endpoints and a brand new documentation site: https://docs.growthbook.io/api. We’re super excited about all of the use cases this unlocks, including the ability to sync experiment results to your data warehouse, one of our most requested features! Read more about the new endpoints and changes on our blog — https://blog.growthbook.io/new-rest-apis

We’ve improved our example repository to include even more examples on how you can integrate GrowthBook with your code. You can check out the examples repo here: https://github.com/growthbook/examples

Other Developer Focused Features and Improvements

• Improved GoLang documentation and examples
• Add variation IDs to experiment feature API payloads on Developers and the work we’ve been doing behind the scenes to enable a world-

Tomorrow, we’ll turn our attention towards the many data scientists and analysts using GrowthBook every day. Stay tuned!
