Dev utils

Dev utils to be shared across 0x projects and packages

Configuration

Some env variables might be set to change the behaviour of created web3 providers/instances.

``
VERBOSE_GANACHE: boolean. Enables verbose Ganache logging. Every request/response payload. Slightly slower, but useful for testing.
SOLIDITY_COVERAGE: boolean. If set - adds coverage subprovider which intercepts all calls/transactions and can be later used to compute code coverage.
`

Boolean env variables should be either true or false. Defaults to false if not set.

Install

`bash
yarn add @0x/dev-utils
`

If your project is in TypeScript, add the following to your tsconfig.json:

`json
"compilerOptions": {
"typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
}
`

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"],
`
