Installation Methods

Should I use the Lambda Layer or the NPM package?

We generally recommend using the Lambda layer as it doesn't require you to deploy any Sentry dependency alongside your function. With the layer, you can achieve the same level of customization as with the NPM package. There are two reasons why you still might want to use the NPM package instead:

1. You want to minimize lambda function size and tree-shake parts of the SDK code that you don't need. A related reason might be because you're transpiling your code and want to transpile your dependencies as well.
2. You already use NPM packages and deploy node_modules with your function and you don't want to add a (or another) Lambda layer to your functions.
