Solana Trader Typescript Client

Provides a Typescript SDK for bloXroute's Solana Trader API.

This library is exposes HTTP, websockets, and GRPC interfaces, and is compatible with both modern browser and node.js environments. Note that some methods and the GRPC interface is only available in node.js run-times, since some aspects of these functions are incompatible with browsers (e.g. http/2 requirement for GRPC, loading from environment, etc.)

Installation

npm i @bloxroute/solana-trader-client-ts

Usage

First, you will need an AUTH_HEADER from bloXroute (see the BDN user portal) . If you wish to create transactions you will also need your Solana PRIVATE_KEY available.

In node.js environments, you can specify both of these values in a .env file, or export them manually yourself. In the browser, you'll want to define them during run-time from user input, and probably use some wallet provider to handle the transaction signing.

A simple example:

import { HttpProvider } from "../bxsolana/provider/http.js"

const provider = new HttpProvider()

let req = await provider.getOrderbook({ market: "SOLUSDC", limit: 5 })
console.info(req)

Refer to the examples/ for more info. As mentioned above, you'll need an .env file for exported variables to execute the full suite. A proper .env file looks like something like this.

AUTH_HEADER="ZDIxYzE0NmItZWYxNi00ZmFmLTg5YWUtMzYwMTk4YzUyZmM4OjEwOWE5MzEzZDc2Yjg3M......................"
PRIVATE_KEY="3EhZ4Epe6QrcDKQRucdftv6vWXMnpTKDV4mekSPWZEcZnJV4huzesLHwASdVUzo......................"

A general note on transaction submission: methods named post* (e.g. postOrder) typically do not sign/submit the transaction, only return the raw unsigned transaction. This is mainly useful for generating transaction in browsers or if you want to handle your signing manually. You may also want to use the similarly named submit* methods (e.g. submitOrder), which generate, sign, and submit the transaction all at once.

Development

We use pbkit/pbkit to generate Typescript files from .proto definitions. You'll need to install their kit:

$ brew install pbkit/tap/pbkit

Clone the repo and install dependencies:

$ git clone https://github.com/bloXroute-Labs/solana-trader-client-ts.git
$ cd solana-trader-client-ts
$ npm i

Lint:

$ npm run lint

Format:

$ npm run format

Install precommit hooks:

$ npx husky install

Regenerate protobuf definitions:

$ npm run proto

How to Publish a new NPM release

We use np to publish new releases to npm. To make a new release, in the project directory use:

$ npm run release

Follow the menu items to select a version for the release (major, minor, patch).
