AWS Lambda build hook

Tip

This page is best viewed through the site search or through the AI.

In this example we hook into the Lambda function build process with hook.postbuild.

This is useful for modifying the generated Lambda function code before it’s uploaded to AWS. It can also be used for uploading the generated sourcemaps to a service like Sentry.

sst.config.ts

new sst.aws.Function("MyFunction", {
  url: true,
  handler: "index.handler",
  hook: {
    async postbuild(dir) {
      console.log(`postbuild ------- ${dir}`);
    },
  },
});

index.js

export async function handler(event,) {
  console.log(event);
  return {
    statusCode: 200,
    body: 'Hello World',
  };
}
