abstractgateway 0.1.1

AbstractGateway: deployable Run Gateway host for AbstractRuntime (commands + ledger).

AbstractGateway

AbstractGateway is a deployable Run Gateway host for AbstractRuntime runs:

• start durable runs
• accept a durable command inbox
• replay/stream a durable ledger (replay-first)
• enforce a security baseline (token + origin allowlist + limits)

This decouples the gateway service from any specific UI (AbstractFlow, AbstractCode, web/PWA thin clients).

Start here: docs/getting-started.md

Quickstart (HTTP server, bundle mode)

pip install "abstractgateway[http]"

export ABSTRACTGATEWAY_FLOWS_DIR="/path/to/bundles"   # *.flow dir (or a single .flow file)
export ABSTRACTGATEWAY_DATA_DIR="$PWD/runtime/gateway"

# Required by default: the server refuses to start without a token.
export ABSTRACTGATEWAY_AUTH_TOKEN="$(python -c 'import secrets; print(secrets.token_urlsafe(32))')"
# Browser-origin allowlist (glob patterns). Default allows localhost; customize when exposing remotely.
export ABSTRACTGATEWAY_ALLOWED_ORIGINS="http://localhost:*,http://127.0.0.1:*"

abstractgateway serve --host 127.0.0.1 --port 8080

OpenAPI docs (Swagger UI): http://127.0.0.1:8080/docs

Smoke checks:

curl -sS "http://127.0.0.1:8080/api/health"

curl -sS -H "Authorization: Bearer $ABSTRACTGATEWAY_AUTH_TOKEN" \
  "http://127.0.0.1:8080/api/gateway/bundles"

Client contract (replay-first)

• Clients start runs: POST /api/gateway/runs/start
• Clients act by submitting durable commands: POST /api/gateway/commands
  • supported types: pause|resume|cancel|emit_event|update_schedule|compact_memory
• Clients render by replaying/streaming the durable ledger:
  • replay: GET /api/gateway/runs/{run_id}/ledger?after=...
  • stream (SSE): GET /api/gateway/runs/{run_id}/ledger/stream?after=...

See docs/api.md for curl examples and the live OpenAPI spec (/openapi.json).

Install

Base (runner + stores + CLI)

Requires Python >=3.10 (see pyproject.toml).

pip install abstractgateway

HTTP API/SSE server (FastAPI + Uvicorn)

pip install "abstractgateway[http]"

Optional extras

• abstractgateway[visualflow]: run VisualFlow JSON from a directory of *.json files (requires abstractflow)
• abstractgateway[telegram]: Telegram bridge dependencies
• abstractgateway[dev]: local test/dev deps

Bundle-dependent dependencies (only if your workflows need them)

• LLM/tool nodes in bundle mode require AbstractRuntime’s AbstractCore integration:

pip install "abstractruntime[abstractcore]>=0.4.0"

For details on ABSTRACTGATEWAY_PROVIDER/MODEL, store backends, and workflow sources, see docs/configuration.md.

Creating a .flow bundle (authoring)

Use AbstractFlow to pack a bundle:

abstractflow bundle pack /path/to/root.json --out /path/to/bundles/my.flow --flows-dir /path/to/flows

See docs/getting-started.md for running, split API/runner, and file→SQLite migration.
