A collection of example tasks for Open SWE
If you want to try out Open SWE, but aren’t sure where to start, here are a few example tasks you can try out.
Below are a series of examples you can try out:
1
Clone the TypeScript template
The examples below are all for TypeScript tasks. For these, you should clone an empty TypeScript template repository:bracesproul/typescript-templateVisit the GitHub UI, and click
Use this template to create a new repository based on this template.2
Give Open SWE access to your repository
If you did not give Open SWE to all of your repositories when setting it up the first time, you’ll need to give Open SWE access to this repository.
- Visit the settings page on Open SWE: swe.langchain.com/settings
- To the right of your user inside the
Current Usersection, click the+button. This will redirect you to GitHub where you can authorize Open SWE to access your repositories. - Select the new TypeScript template you just created.

RESTful “Books” micro-service
RESTful “Books” micro-service
txt Create an Express-based API exposing CRUD endpoints for `/books`. Include request validation with `zod`, proper HTTP status codes, and an in-memory repository layer that can later be swapped for a database. Add Jest tests covering happy-path and a “missing ISBN” error case. WebSocket live counter
WebSocket live counter
txt Add a small WebSocket server (using `ws`) that tracks how many clients are currently connected and broadcasts the updated count every 5 seconds. Expose a health-check HTTP route returning the same value for monitoring tools. Provide a minimal HTML demo page that shows the live number. GitHub issue sync CLI
GitHub issue sync CLI
txt Implement a CLI (`src/sync-issues.ts`) that reads a `config.json` with one or more GitHub repos, fetches their open issues via the GitHub REST API, and writes a local `issues.{owner}.{repo}.csv`. Use `yargs` for parsing and include a `--since YYYY-MM-DD` flag to filter by creation date. JWT + refresh-token auth layer
JWT + refresh-token auth layer
Build a middleware that issues short-lived access tokens and long-lived
Pluggable caching service
Pluggable caching service
txt Design a generic cache interface with `get`, `set`, and `invalidate` methods, then provide two adapters: an in-memory `Map` implementation and a Redis adapter (mock Redis with `ioredis-mock` for tests). Demonstrate hot-swapping the adapter via an environment variable without code changes. GraphQL wrapper over REST API

Locale-aware date utility library
txt Publish an internal `/src/date` module that formats, parses, and time-zone-converts dates using `luxon`. Support at least “en-US”, “de-DE”, and “ja-JP”. Provide type-safe wrappers, exhaustive unit tests, and a benchmark script comparing it to native `Intl.DateTimeFormat`.
