Network

Monorepo containing the main components of Streamr Network.

NPM scripts

Node.js version 20 is recommended.

The monorepo is managed using npm workspaces.

Installation on an Apple Silicon Mac requires additional steps, see install-on-apple-silicon.md.

Important: Do not use npm ci or npm install directly in the sub-package directories.

Bootstrap all sub-packages

The go-to command for most use cases.

To install all required dependencies and build all sub-packages (linking sub-packages together as needed):

# from top level
npm run bootstrap

Bootstrap a single sub-package

To install the required dependencies and build a specific sub-package:

# from top level
npm run bootstrap-pkg --package=$PACKAGE_NAME

Install dependencies only

To only install required dependencies and link sub-packages together (and skip build phase):

# from top level
npm ci

Build

To build all sub-packages:

# from top level
npm run build

Build a sub-package

To build a specific sub-package:

# from top level
npm run build --workspace=$PACKAGE_NAME

Clear caches and built files

To clear all caches and remove the dist directory from each sub-package:

# from top level
npm run clean-dist

Clean all

To removes all caches, built files, and node_modules of each sub-package, and the top-level node_modules:

# from top level
npm run clean

Add a dependency into a sub-package

Manually add the entry to the package.json of the sub-package and run npm run bootstrap-pkg $PACKAGE_NAME.

Alternatively, run:

npm install some-dependency --workspace=$PACKAGE_NAME

List active versions & symlinks

Check which sub-packages are currently being symlinked.

# from top level
npm run versions

This lists sub-packages & their versions on the left, linked sub-packages are columns. If the package on the left links to the package in the column, it shows a checkmark & the semver range, otherwise it shows the mismatched semver range and prints a warning at the end. It prints the version ranges so you can double-check that they're formatted as you expect e.g. ^X.Y.Z vs X.Y.Z

Generate package-lock.json from scratch

Occasionally it can be useful to clear all the packages and generate package-lock.json completely from scratch. To do this run the following.

npm run clean
rm -rf node_modules
rm package-lock.json
npm cache clean --force
npm install

Environment variables

NODE_DATACHANNEL_LOG_LEVEL Adjust logging level of node-datachannel library network-node
BUNDLE_ANALYSIS Whether to produce a bundle analysis when building sdk package for browser sdk (compile time)
STREAMR__BROKER__ Wildcard set of variables used to configure node node

Release

All packages are released at the same time under the same version.

Step 1: Edit the CHANGELOG

You can skip this step if releasing a beta version.

Read and edit CHANGELOG.md. Create a new section for the new version, move items from under "Unreleased" to this new section. Add any additional changes worth mentioning that may be missing from "Unreleased".

Step 2: Creating and pushing the version and tag

In the bash commands below, replace <SEMVER> with the version to be published without the letter "v" infront.

git checkout main
git pull
./update-versions.sh <SEMVER>                                        # e.g. ./update-versions.sh 7.1.1
npm run clean && npm install && npm run build && npm run versions    # Check that the output has not red or yellow markers
git add -p .                                                         # or "git add -all"
./release-git-tags.sh <SEMVER>                                       # e.g. `./release-git-tags.sh 7.1.1`

Step 3: Publish NPM and release Docker image

Firstly, wait for all tests to pass in GitHub Actions.

To publish the NPM packages, use publish-npm workflow. Click button "Run Workflow". Select the right branch and NPM tag to be used.

To publish the Docker image, use release-docker workflow. Click button "Run Workflow". Select the right branch and you are good to go. The Docker tags are automatically chosen based on the associated Git branch and tag.

Step 4: Releasing the docs

Firstly, ask yourself whether the docs need to be released or not.

To publish the docs, use Production Documentation workflow. Click button "Run workflow". Select the right branch and you are good to go.

Manually adjusting Docker image tag latest

GitHub actions will update the latest tag if told to do so in the workflow dispatch drop-down menu. If for whatever reason you want to manually change the latest tag, here are the instructions to do so. Keep in mind that latest should always refer to the latest stable version.

To update latest do the following.

  1. Remove potentially existing latest tag locally with docker manifest rm streamr/node:latest

  2. Find out the sha256 digests of both the amd64 and arm64 builds for a vX.Y.Z tag. This can be done via command-line docker buildx imagetools inspect streamr/node:vX.Y.Z or you can check this from docker hub website under https://hub.docker.com/r/streamr/node/tags.

  3. Then we shall create the manifest by running the below. Remember to replace <SHA-AMD64> and <SHA-ARM64> with real values.

docker manifest create streamr/node:latest \
    --amend streamr/node@sha256:<SHA-AMD64> \
    --amend streamr/node@sha256:<SHA-ARM64>
  1. Then we publish the manifest with
docker manifest push streamr/node:latest
  1. Then we are ready. It would be wise to double-check this by checking https://hub.docker.com/r/streamr/node/tags.
