HTTP IPFS Gateway implemented using Helia

A Dockerized application that implements the HTTP IPFS-gateway API spec and responds to the incoming requests using Helia to fetch the content from IPFS.

$ docker run -it -p 8080:8080 ghcr.io/ipfs/helia-http-gateway:latest

See https://github.com/ipfs/helia-http-gateway/pkgs/container/helia-http-gateway for more information.

$ docker-compose up

$ docker build . --tag helia-http-gateway:local

Pass the explicit platform when building on a Mac.

$ docker build . --platform linux/arm64 --tag helia-http-gateway:local-arm64

$ docker run -it -p 8080:8080 -e DEBUG="helia-http-gateway*" helia-http-gateway:local # or helia-http-gateway:local-arm64

### Build

$ npm run build

$ npm start

See the source of truth for all process.env.<name> environment variables at src/constants.ts.

You can also see some recommended environment variable configurations at:

• ./.env-all
• ./.env-delegated-routing
• ./.env-gwc
• ./.env-trustless-only

Note that any of the following calls to docker can be replaced with something like MY_ENV_VAR="MY_VALUE" npm run start

$ docker run -it -p $RPC_PORT:5001 -p $HTTP_PORT:8080 -e DEBUG="helia-http-gateway*" -e USE_LIBP2P="false" helia

$ docker run -it -p $RPC_PORT:5001 -p $HTTP_PORT:8080 -e DEBUG="helia-http-gateway*" -e USE_BITSWAP="false" helia

$ docker run -it -p $RPC_PORT:5001 -p $HTTP_PORT:8080 -e DEBUG="helia-http-gateway*" -e USE_TRUSTLESS_GATEWAYS="false" helia

$ docker run -it -p $RPC_PORT:5001 -p $HTTP_PORT:8080 -e DEBUG="helia-http-gateway*" -e TRUSTLESS_GATEWAYS="https://ipfs.io,https://dweb.link" helia

We have some tests enabled that simulate running inside of ProbeLab's Tiros, via playwright. These tests request the same paths from ipfs.io and ensure that the resulting text matches. This is not a direct replacement for gateway conformance testing, but helps us ensure the helia-http-gateway is working as expected.

By default, these tests:

1. Run in serial
2. Allow for up to 5 failures before failing the whole suite run.
3. Have an individual test timeout of two minutes.

$ npm run test:e2e # run all tests
$ npm run test:e2e -- ${PLAYWRIGHT_OPTIONS} # run tests with custom playwright options.

$ npm run test:e2e-doctor # Run the dev server with clinicjs doctor, execute e2e tests, and generate a report.
$ npm run test:e2e-flame # Run the dev server with clinicjs flame, execute e2e tests, and generate a report.

Running with METRICS=true will enable collecting Fastify/libp2p metrics and will expose a prometheus collection endpoint at http://localhost:8080/metrics

js-libp2p metrics are collected by default, but can be disabled by setting USE_LIBP2P_METRICS=false. Find out more details at https://github.com/libp2p/js-libp2p/tree/main/packages/metrics-prometheus

See Metrics config for more information on how to view the generated metrics.

$ npm i @helia/http-gateway
