Introduction

Libraries in Dynamo are pieces of reusable code that can be used by multiple pieces of code. A library is usually created when the developer wants to create a piece of shared functionality that should be used in multiple places.

Library Overview

Library code have to be wrapped in a function which is exported using the exports keyword.
Libraries are accessed from the processor context by accessing the library uid as a property on the libs object in a processors context.
Libraries do not have a custom context that gives them access to some of the important Dynamo objects like EntityRepo. To make the processor context available to the library, you would need to call the library with the processor context. Example calling a library called sampleLibrary is shown below:

this.libs.sampleLibrary.call(this, args);
this here refers to a processors context.
