ccp4i2-api 0.3.4

Shared API contract (auth, api-fetch, request/response types) for CCP4i2 and consumers

@ccp4/ccp4i2-api / ccp4i2-api

Shared API contract for CCP4i2 and consumers (CCP4i2 Compounds, third-party integrators) — auth handshake, api-fetch helpers, and request/response types. One package, two language artifacts: TypeScript on the client side (browser, Electron) and Python on the server side (Django middleware, DRF authentication). Both halves agree on the canonical bearer-token format, 401 response shape, and the typed payloads carried over the authenticated channel.

Status

Draft v0 — published to npm + PyPI from the in-tree workspace. Source of truth lives at packages/ccp4i2-api/ inside the ccp4/ccp4i2 monorepo on the django-sliced branch. The npm scope @ccp4 and the PyPI name ccp4i2-api are CCP4-owned (claimed April 2026); a dedicated ccp4/ccp4i2-api GitHub repo may follow later but is not required while the monorepo hosts the source.

Versions 0.1.0–0.3.0 were published under the previous name @ccp4/ccp4i2-auth / ccp4i2-auth; the package was renamed at 0.3.0 because its scope had grown beyond auth to cover the broader API contract. The old name is unpublished/yanked; consumers should depend on @ccp4/ccp4i2-api and ccp4i2-api from 0.3.0 onward.

Versioning follows semver from 0.x.y onwards. The v0 contract is documented in docs/CCP4I2_SERVICE_CONTRACT.md; field stability promises take effect from this version.

Layout

Path	Purpose
src/	TypeScript source. Built to lib/ via npm run build.
lib/	Built TypeScript output. Generated; gitignored.
dist/	Python distribution output (python -m build). Generated; gitignored. Kept distinct from lib/ so twine upload dist/* doesn't accidentally pick up TypeScript artefacts.
ccp4i2_api/	Python source. Installed editable via pip install -e ..
tests/js/	TypeScript tests (vitest, when added).
tests/python/	Python tests (pytest, when added).

Consumer wiring

In-monorepo consumers can reference this package by local path for fast iteration; out-of-monorepo consumers pull the published versions.

TypeScript — in-monorepo (client/package.json):

"dependencies": {
  "@ccp4/ccp4i2-api": "file:../packages/ccp4i2-api"
}

(Path depth varies by consumer location.) Out-of-monorepo consumers use the published range, e.g. "@ccp4/ccp4i2-api": "^0.3.0".

Python — in-monorepo (Docker/server/Dockerfile, local dev setup):

pip install -e packages/ccp4i2-api/

Out-of-monorepo consumers pip install ccp4i2-api>=0.3.

Development

# TypeScript
cd packages/ccp4i2-api
npm install
npm run build       # produces lib/
npm run watch       # rebuilds on change

# Python
cd packages/ccp4i2-api
ccp4-python -m pip install -e .
ccp4-python -c "import ccp4i2_api; print(ccp4i2_api.__version__)"
