JavaScript and TypeScript
The TypeScript client supports code that is written in TypeScript or JavaScript.
The TypeScript client v3 supports Node.js server based development. It does not support browser based web client development. To develop a browser based application, use the v2 client.
Clients
The v3 client is the current TypeScript client. If you have code written for the v2 client, you should migrate it to v3.
The v2 client version is still available in npm, however you should not use it to begin new projects.
If you have suggestions or comments on how to improve the new client, let us know:
Older clients
The v3 TypeScript client replaces the v2 JavaScript only client. The JavaScript client is no longer supported. If you have older code that uses the JavaScript client, update to the TypeScript client.
