rust-wasm-on-lambda-edge VS coldsnap

AWS Lambda@Edge is much, much more convoluted because IIRC you can only run node and python there. In other words, you have to use some glue to make it work.

I adopted a rollup based approach, since it's quite easy to get configured and also something we use at work. I always found webpack a little bit too cumbersome, and parcel is just yet another new kid on the block. I'm pretty sure you can adjust the project to your needs. All we need here is: compile TS to JS and bundle up everything into a single JS file. In the past I found the WebAssembly dependency management very tricky, in the end I used a plain "move the .wasm file into the final bundle" approach, which just works fine, because I did not want to inline the WebAssembly code (as most plugins try). Maybe you have a smarter solution for that, please open a pull-request in the repo. Just keep in mind: wasm-bindgen creates already a pretty decent module loader, so there is no need to work around that, but I fail to get any of these bundlers to move the wasm files along with it into the bundle output directory.

I haven’t tried with lightsail but it should work the same. Also, if you want to and have th storage, you can use something like coldsnap to download the snapshot as a disk image. You can put it back the same way and restore to start the instance later if you want. This way you don’t even need to pay for the snapshot.
