# Webmail image for integration testing — runs Next.js in DEVELOPMENT mode.
|
|
#
|
|
# Why dev mode rather than the production Dockerfile at the repo root?
|
|
# The browser talks JMAP directly to Stalwart at http://localhost:8025 (plain
|
|
# HTTP, cross-origin). The app's production Content-Security-Policy pins
|
|
# connect-src to `'self' https:`, which would block that plaintext cross-origin
|
|
# fetch. In development mode proxy.ts widens connect-src to `'self' http:
|
|
# https: ws: wss:` — exactly what a local, TLS-less Stalwart needs. Running
|
|
# from source also ships the integration-test data-testid hooks without a
|
|
# production rebuild.
|
|
#
|
|
# Build context is the repo root (see docker-compose.yml `context: ..`), so the
|
|
# root .dockerignore keeps examples/, integration/ and node_modules out.
