Before running the test server for the first time, copy ".env.example" as ".env" and replace the variables in '.env' with your own variables. Run `pnpm dev` to run the test server. It will open up to the home page automatically in your default browser. For more details visit the [Test Server README.md](/test-server/README.md) ### Troubleshooting If you ever see an error that looks like this while running an Nx command (pnpm test, pnpm build, etc...): ``` Lerna (powered by Nx) DB transaction operation error: SqliteFailure(Error { code: SystemIoFailure, extended_code: 522 }, Some("disk I/O error")) ``` Run `npx nx reset` and try again ## Documentation See our [Typescript SDK](https://amplitude.github.io/Amplitude-TypeScript/) Reference for a list and description of all available SDK methods.
