There is an example here:

Basically use functional programming approach, write high-order functions

Pro:

• Not forced to use anything unnecessary

• Has full control

Con:

• Need more time to write the middle ware - cannot just fetch ready middleware and use

• Quality of hand-written middleware may not reach to maturity (security) of available solutions

In case of building own middleware, each middleware can be built as (https://dbartholomae.github.io/lambda-middleware/):

(options) => (handler) => (event, context) => Response

It just uses high-order function and compose to do the work.
