terraform-provider-node-lambda-packager

terraform-provider-node-lambda-packager

This Terraform provider helps you to co-locate your Lambda application code with your Infrastructure as Code (IaC). It uses esbuild to produce a bundle that's then zipped up and made ready for Terraform to consume.

Usage

#
# 1. Use the data source to package up your NodeJS-based Lambda function.
#
data "node-lambda-packager_package" "create_user" {
  #
  # 2. Set esbuild arguments as appropriate.
  #
  # See: https://esbuild.github.io/api/#build-api
  #
  args = [
    "--bundle",
    "--minify",
    "--platform=node",
    "--sourcemap",
    "--target=es2024",
    "--sourcemap=inline",
  ]

  #
  # 3. The entrypoint file is relative to the working directory and you can
  #    leave the working directory empty if it's already correct.
  #
  entrypoint        = "src/handlers/v1/admin/users/create/index.ts"
  working_directory = ""
}

#
# 4. Define your Lambda function as normal!
#
resource "aws_lambda_function" "create_user" {
  function_name = "create-user"
  role          = aws_iam_role.create_user.arn
  architectures = ["arm64"]
  handler       = "index.handler"
  memory_size   = 1024
  runtime       = "nodejs22.x"

  #
  # 5. Here's where our data source is used:
  #
  filename         = data.node-lambda-packager_package.create_user.filename
  source_code_hash = data.node-lambda-packager_package.create_user.source_code_hash
}

Build

make build

Install for local testing

make install

Test

make testacc

Linting

For install steps, see golang-ci-lint on GitHub. Find the correct version to use in the ./github/workflows/golangci-lint.yml file.

golangci-lint run

Fixing formatting or input problems

You can run a single linter in fix mode as follows:

golangci-lint run --no-config --enable gofumpt --fix

gci and gofumpt have to be run in order to have both agree about the import order and formatting:

golangci-lint run --no-config --enable gci --fix
golangci-lint run --no-config --enable gofumpt --fix
