Create a Demo Layer with `axios` Using PowerShell

PowerShell script creating a Node.js project with `axios` for AWS Lambda layer.

Learn how to create an AWS Lambda layer with `axios` using PowerShell in a few simple steps.


Module 1: Create a Demo Layer with axios Using PowerShell #

  1. Open PowerShell.

  2. Navigate to your working directory or create a new one:

    New-Item -ItemType Directory -Path my-lambda-layer
Set-Location -Path my-lambda-layer

  3. Initialize a new Node.js project:

    npm init -y

  4. Install axios:

    npm install axios

  5. Create the necessary directory structure for the layer:

    New-Item -ItemType Directory -Path layer/nodejs -Force

  6. Move the node_modules and package.json to the layer directory:

    Move-Item -Path node_modules -Destination layer/nodejs
Move-Item -Path package.json -Destination layer/nodejs

Your directory structure should now look like this:

my-lambda-layer/
└── layer
    └── nodejs
        ├── node_modules
        │   └── axios
        └── package.json
  1. Zip the layer/nodejs directory:
    Compress-Archive -Path layer/nodejs -DestinationPath my-lambda-layer.zip

You now have a zipped file, my-lambda-layer.zip, which contains the axios library and can be uploaded as a Lambda layer in AWS.

To upload and use the layer in AWS Lambda:

  1. Go to the AWS Lambda Console.
  2. Navigate to "Layers" and click "Create layer".
  3. Provide a name for the layer, upload the my-lambda-layer.zip file, and specify the compatible runtimes (e.g., Node.js 14.x, Node.js 16.x).
  4. Click "Create".

After creating the layer, you can add it to your Lambda function:

  1. Go to your Lambda function in the AWS Console.
  2. In the "Layers" section, click "Add a layer".
  3. Choose "Custom layers" and select the layer you just created.
  4. Click "Add".

Now, your Lambda function will have access to the axios library, and you can use it in your Lambda handler code.
