Welcome to the [Deployer](https://github.com/0xProject/0x-monorepo/tree/development/packages/deployer) documentation! Deployer is a tool for compiling and deploying Solidity smart contracts with ease. It serves a similar purpose as parts of the [Truffle framework](http://truffleframework.com/), but with the UNIX philosophy in mind: Make each program do one thing well. This tool is for intermediate to advanced Solidity developers that require greater configurability and reliability. Deployer has the following advantages over Truffle: * Deploy each smart contract with a specific version of Solidity. * Improved artifact files: * Properly segregated artifacts to support storing different versions of smart contract deployed on different networks. * Storage of constructor args, source maps and paths to all requisite source files. * An easy to maintain codebase: TypeScript + Single repo. * Allows you to specify the deployer RPC address. * Supports Solidity version ranges - contract compiled with latest Solidity version that satisfies the range. * Migrations that work with `async/await`. * Migrations that can be written synchronously in order to guarentee deterministic contract addresses. * No race conditions when running migrations. Deployer can be used as a command-line tool or as an imported module.
