@0x/sol-compiler

Sol-compiler is a wrapper around solc-js that adds:

• Smart re-compilation: Only recompiles when smart contracts have changed
• Ability to compile an entire project instead of only individual .sol files
• Compilation using the Solidity version specified at the top of each individual .sol file
• Proper parsing of Solidity version ranges
• Support for the standard input description for what information you'd like added to the resulting artifacts file (i.e 100% configurable artifacts content).
