# TypeScript Modules (Beta)

TypeScript/JavaScript modules are finally here! We're extremely excited to announce v1.6. For the first time in several years we've added a new server module language, and it required a whole new runtime! SpacetimeDB now ships with v8.

In order to get started with TypeScript modules, follow our [quickstart guide](https://spacetimedb.com/docs/modules/typescript/quickstart) or read the module API [reference](https://spacetimedb.com/docs/modules/typescript). Publishing a TypeScript module is almost exactly the same as publishing a Rust or C# module. In order to get started simply run:

```sh
spacetime init --lang typescript # in the appropriate directory
spacetime publish <your-module-name> # in the directory with your package.json
```

The `spacetime` CLI tool will look for `src/index.ts` and automatically bundle your application and upload it to SpacetimeDB.

> ⚠️ BETA NOTICE: TypeScript modules are currently in beta. As a result performance is not representative of the final product. If you encounter bugs or other issues, please file a new issue [here](https://github.com/clockworklabs/SpacetimeDB/issues/new) with the `typescript-modules` label.

# Other Features

In v1.6 we are now also adding additional schema migration support, including adding columns to tables! In order to add a column, just add a column to the end of your table definition, specify a default value, and push the new module. The CLI will warn you if your new schema is compatible with existing clients, and will disconnect the appropriate clients if required by the migration. This is one more step in our journey to provide a world class schema migration experience for your apps and games.
