Utilities for working with Serverless.

API

utils.Handler(fn)

Create a SLS event handler, abstracting away oddities with responses and async functions.

Example:

const { Handler } = require('@stephenmathieson/sls-utils')

// Create your service.
const fooService = new Handler(async (event, context) => {
  const { body: rawBody } = event
  const { foo, bar, baz } = JSON.parse(rawBody)

  const data = await getData(foo, bar, baz)
  return data
})

// Export its handler.
exports.foo = fooService.getHandler()

utils.getHeader(name, headers)

Get the value of the name header, or null.

Useful because AWS does not normalize (lowercase) headers.

Example:

exports.foo = (event, context, callback) => {
  const authorization = getHeader('authorization', event.headers)
  if (!authorization) {
    // ...
  }
}
