Prerequisites

Cloning

This repository uses git submodules. To clone this repo with submodules

git clone --recurse-submodules git@github.com:TBD54566975/tbdex-js.git

Or to add submodules after cloning

git submodule update --init

We recommend running the command below once which will configure your environment to only checkout the hosted directory under the tbdex git submodule directory, which contains files relevant to this repo, such as tbDEX spec test vectors and schemas.

git -C tbdex sparse-checkout set hosted

Hermit

This project uses hermit to manage tooling like node. See this page to set up Hermit on your machine - make sure to download the open source build and activate it for the project

Currently, we have these packages installed via Hermit (can also view by checking out hermit status):

• node
• pnpm

You can run hermit upgrade {package} to upgrade an existing package, or hermit install {package} to install a new package. Please see Hermit package management page for more details.

Running Tests

Note

Make sure you have all the prerequisites

0. clone the repo and cd into the project directory
1. Install all project dependencies by pnpm install
2. Build all workspace projects in this repo by running npm run build
3. run tests using pnpm test:node to run tests within a nodejs runtime
4. run tests using pnpm test:browser to run tests within a browser runtime. Before doing so, run npx playwright install --with-deps, only required once.

pnpm scripts

Script	Description
pnpm clean	deletes dist dir and compiled tests
pnpm test:node	runs tests in node runtime
pnpm test:browser	runs tests in headless browsers (chrome, safari, firefox)
pnpm lint	runs linter without auto-fixing
pnpm lint:fix	runs linter and applies automatic fixes wherever possible
pnpm build	builds all distributions and dumps them into dist

Publishing a new release

This project uses Changesets for semver management and releases. For motivations, see PR description here.

Release workflow:

1. Open a PR
2. changeset-bot will automatically comment on the PR with a reminder & recommendations for semver
3. Run pnpm changeset locally and push changes (.changet/*.md). The CLI tool will walk you through a set of steps for you to define the semantic changes and create a randomly-named markdown file within .changeset/.
4. Merge PR into main.
5. Profit from the automated release pipeline:
   • Release Workflow will create a new Version Package PR, or update the existing one. For example, see this PR. This PR updates the version numbers in the relevant package.json files & also aggregates the Summary notes into the relevant CHANGELOG.md files.
   • When maintainers are ready to publish the new changes, they will merge that PR and the very same Release Workflow will automatically publish a new version to NPM, and publish the docs to https://tbd54566975.github.io/tbdex-js/

Note

This is all achieved by the Changesets GitHub action being used in the Release Workflow.
