In web3 wrapper when a response contains an error field we throw this rather than return response.result which is often undefined. In Signature Utils we handle the error thrown when a user rejects the signing dialogue to prevent double signing. Exposed the ZeroExTransaction JSON schema. In Website only use the MetamaskSubprovider if we can detect the provider is Metamask
@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"],
