0x.js
A TypeScript/Javascript library for interacting with the 0x protocol. It is a high level package which combines a number of underlying packages such as order-utils and asset-data-utils.
Read the Documentation.
Installation
0x.js ships as both a UMD module and a CommonJS package.
CommonJS (recommended):
Install
npm install 0x.js --save
Import
import {
assetDataUtils,
BigNumber,
ContractWrappers,
generatePseudoRandomSalt,
orderHashUtils,
signatureUtils,
} from '0x.js';
If your project is in TypeScript, add the following to your tsconfig.json:
"compilerOptions": {
"typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
}
UMD:
Install
Download the UMD module from our releases page and add it to your project.
Import
<script type="text/javascript" src="0x.js"></script>
Webpack config
If bundling your project with Webpack, add the following to your webpack.config.js:
If building for web:
node: {
fs: 'empty';
}
If building a node library:
externals: {
fs: true;
}
ContractWrappers uses WebAssembly to simulate Ethereum calls. This toolchain involves generated 'glue' code that requires the fs built-in, but won't actually use it in a web environment. We tell Webpack not to resolve them since we won't need them. The specific dependency is here.
