Serverless Stack

does sst use webpack under the hood for all lambda functions?

ok, I'm trying to use knex as a query builder and there is a known problem where it doesn't exclude unused database drivers (e.g. 'ps', 'mysql', 'sqlite3') and causes the bundler to throw a fit

is there anywhere I would mark external libraries for esbuild?

yep on the function definition you can set `bundle.external = ["pg", "mysql"]`

we also have `bundle.nodeModules` which will mark as external but also install the package into the lambda before uploading

bundle.external goes inside the function definition or in the global scope?

<https://docs.serverless-stack.com/constructs/Function#externalmodules>

you can also use app.setDefaultFunctionProps if you want to set it globally

Yeah i just reazlied its in the stack definition and changed it in the API construct
