@0xproject/utils
Utils to be shared across 0x projects and packages
Installation
yarn add @0xproject/utils
If your project is in TypeScript, add the following to your tsconfig.json:
"compilerOptions": {
"typeRoots": ["node_modules/@0xproject/typescript-typings/types", "node_modules/@types"],
}
Usage
import { addressUtils, bigNumberConfigs, classUtils, intervalUtils, promisify } from '@0xproject/utils';
Troubleshooting
If you are still seeing TS type errors complaining about missing DOM types such as Response:
error TS2304: Cannot find name 'Response'.
Then you need to explicitly add the dom lib to your compiler options in tsconfig.json. The dom library is included by default, but customizing the lib option can cause it to be dropped.
"compilerOptions": {
"lib": [..., "dom"],
