为 nodejs 添加对现有 AWS lambda 函数的依赖

Question

I want to update my AWS lambda function that is already deployed to AWS.

The lambda is a nodejs function

It has a javascript, package.json and package-lock.json

There is no code or steps that I can find to help with that is clear steps on AWS docs.

I looked for them but I get how to create a function.

Also to be noted I do not have the original code on git or anything. What I have is in the lambda function.

I also need to install an npm package to the function as part of updating.

You can use GetFunction get the function details which will give you path of s3 from which you can download the code. More details - https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html#getFunction-property

For Updating the function code use UpdateFunctionCode - https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html#updateFunctionCode-property

For Updating function configuration use UpdateFunctionConfiguration - https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html#updateFunctionConfiguration-property
