The LangchainCommonDepsLayer class.
Constructnew LangchainCommonDepsLayer(
scope,id,props):LangchainCommonDepsLayer
This construct creates a lambda layer loaded with relevant libraries to run genai applications. Libraries include boto3, botocore, requests, requests-aws4auth, langchain, opensearch-py and openai.
• scope: Construct
represents the scope for all the resources.
• id: string
this is a a scope-unique id.
• props: LangchainLayerProps
user provided props for the construct.

Construct.constructor
readonlylayer:LayerVersion
Returns the instance of lambda.LayerVersion created by the construct
readonlynode:Node
The tree node.
Construct.node
toString():
string
Returns a string representation of this construct.
string
Construct.toString
staticisConstruct(x):x is Construct
Checks if x is a construct.
Use this method instead of instanceof to properly detect Construct
instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs library on
disk are seen as independent, completely different libraries. As a
consequence, the class Construct in each copy of the constructs library
is seen as a different class, and an instance of one class will not test as
instanceof the other class. npm install will not create installations
like this, but users may manually symlink construct libraries together or
use a monorepo tool: in those cases, multiple copies of the constructs
library can be accidentally installed, and instanceof will behave
unpredictably. It is safest to avoid using instanceof, and using
this type-testing method instead.
• x: any
Any object
x is Construct
true if x is an object created from a class which extends Construct.
