Introducing Cloud Firestore: Our New Document Database for Apps

Today we’re excited to launch Cloud Firestore, a fully-managed NoSQL document database for mobile and web app development. It’s designed to easily store and sync app data at global scale, and it’s now available in beta.

Key features of Cloud Firestore include:

  • Documents and collections with powerful querying
  • iOS, Android, and Web SDKs with offline data access
  • Real-time data synchronization
  • Automatic, multi-region data replication with strong consistency
  • Node, Python, Go, and Java server SDKs

And of course, we’ve aimed for the simplicity and ease-of-use that is always top priority for Firebase, while still making sure that Cloud Firestore can scale to power even the largest apps.

Introducing Slack JS 9.0.0

Super stoked to share the latest version of our JS client for the Slack Web API! You can find the source code here and the npm distribution here.

Speed is 🔑

Apps built for Slack by their nature are real time. All facets of speed are critical factors for creating a great user experience. And with performance as our guide I am very pleased to say we support the entire Slack Web API in a 7kb (not gzip’d) payload that has been solidly tested for all LTS versions of Node and modern evergreen browsers.

Being so tiny means this library loads super fast which makes it perfect for AWS Lambda and browser-based applications where cold start responsiveness is critical.

Learn Blockchains by Building One

You’re here because, like me, you’re psyched about the rise of Cryptocurrencies. And you want to know how Blockchains work—the fundamental technology behind them.

But understanding Blockchains isn’t easy—or at least wasn’t for me. I trudged through dense videos, followed porous tutorials, and dealt with the amplified frustration of too few examples.

I like learning by doing. It forces me to deal with the subject matter at a code level, which gets it sticking. If you do the same, at the end of this guide you’ll have a functioning Blockchain with a solid grasp of how they work.
