Ignore tests in lambda folder

I'm just setting my lambda functions and have the following directory structure

src/
  lambda/
    hello.js
    hello.test.js

Which follows how the rest of the app gets tested.

Unfortunately this means running netlify-lambda build src/lambda results in my tests also being built and installed as if they are lambda functions.

Is there a way to exclude all *.test.js or *.spec.js files?

davesag commented

for now I work around this by simply adding this script in package.json

"lambda:build": "netlify-lambda build src/lambda",
"postlambda:build": "rm lambda/*.test.js",

but it would be nicer to exclude them during the lambda:build step.

Somewhat unrelated but since you're using Webpack it might be helpful.. I stumbled upon this issue a while back and a couple days ago I added a way to resolve it within 8eecf0d2/netlify-local by allowing users to specify a files array which can be used to compose a Webpack Configuration entry property.

The bundle command docs probably give the best description of how it works, it also flattens nested handlers by replacing forward slashes with dashes (eg, "lambda/nested/handler.js" => "lambda-nested-handler.js").

You can use the logic programatically like so:

const netlifyLocal = require("netlify-local");
const netlifyConfig = netlifyLocal.parseNetlifyConfig("netlify.toml");

module.exports = {
  entry: netlifyLocal.composeWebpackEntry(netlifyConfig),
  ...
}

As far as the issue itself goes, it's a bit of a pain this is the same behaviour as production - to request changes in the production environment you'll need to talk to Netlify Support.

@sw-yx is there a specific / technical support link I should be promoting?

@8eecf0d2 that is -the- canonical netlify support link, you got it :)

hey @davesag , the really really easy way to do this is just dont put the lambda folder in src :) you can put it in a foobar folder if you like. just change your netlify serve _____ and netlify build _____ command accordingly

in fact i really dislike encouraging people to colocate lambda functions and client code. causes potential confusion. problem is we've been recommending it for a while.
