Node.js SDK
Start developing with Square in a matter of minutes. The Square Node.js SDK supports Square APIs in a language-idiomatic way that reduces complexity without sacrificing API functionality. The single downloadable package contains all the code and documentation you need to get started.
Note
After December 16, 2020, the deprecated Connect Node.js SDK will not receive any bug fixes or API updates, but it will receive support and security patches until it is retired (EOL) in Q2, 2021.
For information about how to migrate from the deprecated Connect Node.js SDK to the Square Node.js SDK, see the Connect SDK README.
