Asana | emulate

A stateful, in-memory Asana REST API (v1.0) emulator.

Included now:

Users, workspaces, teams, projects, sections, tasks, tags, stories, webhooks
Subtasks, task dependencies/dependents, followers, project/section membership
Bearer-token auth and offset-based pagination (limit 1–100, offset)

Follow-up work will add OAuth 2.0 and an inspector UI.

Start

# From this repo (after `bun install && bun run build`)
bun packages/emulate/dist/index.js --service asana

# Or from the published package
npx @pleaseai/emulate --service asana

A single service starts on the base port (default 4000). Use -p <port> to change it. When started alongside other services, ports are assigned sequentially from the base port (asana’s slot is 4005).

Default URL (asana alone):

http://localhost:4000

Auth

All /api/1.0/* routes require a bearer token. Any token works — an unmatched token resolves to the first seeded user, so me keywords work out of the box.

curl http://localhost:4000/api/1.0/users/me \
  -H "Authorization: Bearer test-token"

Map specific tokens to users via the top-level tokens key in the config:

tokens:
  test-token:
    login: dev@example.com # matches a seeded user's email, gid, or name
    scopes: []

Conventions

Write bodies are wrapped in data: {"data": {"name": "My Task"}}.
Successful responses are wrapped in data; lists add a next_page cursor.
Errors return {"errors": [{"message": "..."}]}.

Example

# Create a task (assigned to the authenticated user)
curl -X POST http://localhost:4000/api/1.0/tasks \
  -H "Authorization: Bearer test-token" \
  -H "Content-Type: application/json" \
  -d '{"data":{"name":"Write the README","projects":["<project_gid>"],"assignee":"me"}}'

# List tasks in a project
curl "http://localhost:4000/api/1.0/tasks?project=<project_gid>&limit=50" \
  -H "Authorization: Bearer test-token"

Seed Config

Add an asana: section to emulate.config.yaml (or pass --seed <file>). Inter-entity references are resolved by name; the workspace defaults to the first one when omitted.
