Framework Developers

This file is intended for developers working on the internals of the framework. If you're just looking how to get started with the framework, see the docs

Environment Setup

VSCode devContainer

This project comes with a .devcontainer to make it as easy as possible to setup your dev environment and begin contributing to this project.

All the environment variables noted below can be added to devcontainer.env and exposed to the development docker container.

When running in a container your project root directory will be /work. Use this to correctly path any environment variables, for example:

GENESIS_TXN_PATH=/work/network/genesis/local-genesis.txn

Running tests

Test are executed using jest. E2E tests (ending in .e2e.test.ts) require the indy ledger, cheqd ledger or postgres database to be running.

When running tests that require a connection to the indy ledger pool, you can set the TEST_AGENT_PUBLIC_DID_SEED, ENDORSER_AGENT_PUBLIC_DID_SEED and GENESIS_TXN_PATH environment variables.

Quick Setup

To quickly set up all services needed to run tests (Postgres, Hyperledger Indy Ledger, and Cheqd Ledger), run the following command:

docker compose up -d

If you're running on an ARM based machine (such as Apple Silicon), you can use the docker-compose.arm.yml file instead:

docker compose -f docker-compose.arm.yml up -d

Run all tests

You can run all unit tests (which do not require the docker services to be running) using the following command.

yarn test:unit

To run the e2e tests:

yarn test:e2e

You can also run all tests:

yarn test

Setting environment variables

If you're using the setup as described in this document, you don't need to provide any environment variables as the default will be sufficient.

  • GENESIS_TXN_PATH: The path to the genesis transaction that allows us to connect to the indy pool.
    • GENESIS_TXN_PATH=network/genesis/local-genesis.txn - default. Works with the ledger setup from the previous step.
    • GENESIS_TXN_PATH=network/genesis/builder-net-genesis.txn - Sovrin BuilderNet genesis.
    • GENESIS_TXN_PATH=/path/to/any/ledger/you/like
  • TEST_AGENT_PUBLIC_DID_SEED: The seed to use for the public DID. This will be used to do public write operations to the ledger. You should use a seed for a DID that is already registered on the ledger.
    • If using the local or default genesis, use the same seed you used for the add-did-from-seed command from the ledger setup in the previous step. (default is 000000000000000000000000Trustee9)
    • If using the BuilderNet genesis, make sure your seed is registered on the BuilderNet using selfserve.sovrin.org and you have read and accepted the associated Transaction Author Agreement. We are not responsible for any unwanted consequences of using the BuilderNet.
  • ENDORSER_AGENT_PUBLIC_DID_SEED: The seed to use for the public Endorser DID. This will be used to endorse transactions. You should use a seed for a DID that is already registered on the ledger.
    • If using the local or default genesis, use the same seed you used for the add-did-from-seed command from the ledger setup in the previous step. (default is 00000000000000000000000Endorser9)
    • If using the BuilderNet genesis, make sure your seed is registered on the BuilderNet using selfserve.sovrin.org and you have read and accepted the associated Transaction Author Agreement. We are not responsible for any unwanted consequences of using the BuilderNet.
