Documentation
Documentation for this package is generated by TypeDoc, using the Solidity source code for 0x contracts. Each contract corresponds to one global-level module, which contains relevant enums and interfaces for its events and structs. Most significantly, each module exports a class, <ContractName>Contract, e.g. ExchangeContract, which implements helper methods for all the functions defined in the corresponding contract.
A convention to note is that these contract-specific helper methods are defined as object literals, which are separated from methods in the generated documentation. Each contract method has a number of sub-methods, e.g. sendTransactionAsync, or estimateGasAsync, which are documented separately. This is an example of an expected method call signature: exchangeContractInstance.fillOrder.sendTransactionAsync(...arguments).
Development
This package contains generated code. We use the abi-gen utility to generate wrappers from compiler artifacts in @0x/contract-artifacts. To re-generate wrappers, e.g. when @0x/contract-artifacts has been updated, run yarn wrappers:generate && yarn wrappers:prettier.
