Is it possible to hot-reload template.yaml?

Hot reloading source files with aws-sam-webpack-plugin is such a wonderfull and convenient thing that it's hard to remember why things stopped to work after adding another lambda to template.yaml :)

So the question is is it really possible to hot-reload template.yaml when it's been changed?

You might be able to use nodemon to restart webpack but I can't see another solution. The only time the entry points can be set in the webpack.config.js is when webpack loads it. If they provide another way to set them then I'm happy to revisit this request.

After re-reading the Webpack docs I'm going to change the recommended webpack.config.js from entry: awsSamPlugin.entry() to entry: () => awsSamPlugin.entry() which will cause it to reload the entry points each time it builds. It will still only build once a source file is changed (not template.yaml) but you'll always be building from the most recently saved template.yaml.

Wow. I missed that entry-function feature in webpack. Thanks.

Yeah, I'm already using nodemon.

I know that webpack plugins can add dependencies to watch into webpack while building projects.
May be awsSamPlugin could do that for template.yaml?
Then it wouldn't need to use nodemon.
This will allow to escape repeating file names and is gonna be less error-prone.

P.S. There is also one trick, if awsSamPlugin.entry is not a method of a class, but just a field with a function, then it can be used like entry: awsSamPlugin.entry, without brackets.

I'm not planning to add further support for hot reloading based on the template.yaml changing.
