Install dependencies

If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:

yarn config set workspaces-experimental true

Then install dependencies

yarn install

Build

To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:

PKG=@0x/subproviders yarn build

Or continuously rebuild on change:

PKG=@0x/subproviders yarn watch

Clean

yarn clean

Lint

yarn lint

Run tests

Unit tests

yarn run test:unit

Integration tests

In order to run the integration tests, make sure you have a Ledger Nano S available.

  • Setup your Ledger with the development mnemonic seed: concert load couple harbor equip island argue ramp clarify fence smart topic
  • Plug it into your computer
  • Unlock the device
  • Open the on-device Ethereum app
  • Make sure "browser support" and "contract data" are disabled
  • Start TestRPC locally at port 8545

Then run:

yarn test:integration

Note: We assume a derivation path of m/44'/60'/0'/0 which is already configured in the tests. With this setup and derivation path, your first account should be 0x5409ed021d9299bf6814279a6a1411a7e866a631, exactly like TestRPC.

All tests

yarn run test:all
