The v4-Client Typescript client is used for placing transactions and querying the dYdX chain.

Development

v4-client-js uses node v18 for development, see the .nvmrc file here. You can use nvm to manage different versions of node.

nvm install
nvm use
nvm alias default $(nvm version) # optional

You can run the following commands to ensure that you are running the correct node and npm versions.

node -v # expected: v18.x.x (should match .nvmrc)
npm -v  # expected: 8.x.x

1. Clone or fork the V4 clients repo

git clone [email protected]:dydxprotocol/v4-clients.git

2. Go to one of the examples

• Go to v4-client-js/examples

cd v4-client-js/examples

These examples by default use a test account with DYDX_TEST_MNEMONIC from the TS client library under v4-client-js/examples/constants.

3. Run the scripts with node

npm install
npm run build

You should now see a /build/examples dir generated with JS files. We will use node to run these scripts

• Open a terminal to run an example, e.g. account_endpoints.

node ../build/examples/composite_example.js

Everytime you change the TS code, you need to run npm run build again, before you execute using node.

Single-JS for mobile apps

Mobile apps needs to load JS as a single JS file. To build, run

npm run webpack

The file is generated in native/ios/v4-native-client.js Pending: Different configurations may be needed to generate JS for Android app

Release

Using the npm version command will update the appropriate version tags within the package locks and also will add a git tag with the version number.. For example npm version minor will perform the necessary changes for a minor version release. After the change is merged, a GitHub action will publish the new release.
