feat: convert to ESM (breaking change) #856

kanadgupta · 2023-08-09T23:14:14Z

🚥 Partially addresses #801

🧰 Changes

This PR refactors the entire repository over to full ESM. This entailed a few different refactors:

Using .js file extensions for relative imports (really wish I had done this after discovering eslint-plugin-require-extensions) 😭
Updated a bunch of dependencies to their latest ESM counterparts
- (with the exception of ora, see the outstanding issues below)
- Some of our upstream dependencies now use native Node 18 fetch so a test or two had to be updated accordingly. Eventually we'll want to migrate away from nock entirely.
Setting module: NodeNext in our tsconfig.json and type: module in our package.json
In order to build the single-file executable binaries used in our Docker/GitHub Actions builds, we now compile this entire repository into CJS using Rollup before sending it into pkg 😵‍💫 (see ES modules not supported vercel/pkg#1291)
- This obviously isn't ideal, but pkg handles a lot of the madness of compiling into single-file executables better than anything else I've tried (see here for more context)
- A huge benefit here is that our Docker image sizes should be around 25% smaller 📉

Outstanding tasks/issues

Below is a running list of outstanding work — the ora issue is mostly out of our hands, but I'll look into the ExperimentalWarning in a follow-up PR.

Unable to update to the latest version of ora due to segmentation faults at runtime, see ora@7 dependency causes seg fault (was seg fault on mac m1 arm) sindresorhus/ora#229 for more information
Figure out if there's a non-shitty way to hide this warning (edit: I tried fixing this in eeeabd9 but it proved to be problematic for a variety of reasons):

(node:92816) ExperimentalWarning: Import assertions are not a stable feature of the JavaScript language. Avoid relying on their current behavior and syntax as those might change in a future version of Node.js.
(Use `node --trace-warnings ...` to show where the warning was created)
(node:92816) ExperimentalWarning: Importing JSON modules is an experimental feature and might change at any time

Unable to properly load in some of our packages
- oas (see fix: get exports working in TS nodeNext oas#796)
- oas-normalize (see fix: get exports working in TS nodeNext oas-normalize#294)
tsconfig cleanup (e.g., do we need downlevelIteration?) (edit: nah let's do this further down the line, we're already introducing a lot of new breaking changes as is)
Move some of these .cjs files over to .js
Unable to build executable for usage in Docker/GitHub Actions

🧬 QA & Testing

Our existing end-to-end tests GitHub Actions tests are passing, meaning this should work, but I'll do some more QA once we tag a beta release.

You can confirm this all works locally by doing the following:

# install/build
npm ci && npm run build:exe

# run the JS output (used by npm-based CLI installations)
bin/rdme.js openapi:validate # or whatever command you want

# run the binary
./exe/rdme openapi:validate  # or whatever command you want

this probably won't work with node 14 at all ugh

most of them are now .cjs with the exception of bin/rdme.js

can we move off jest? all my homies hate jest

kanadgupta · 2023-08-10T14:29:34Z

Update: while I made substantial progress on this, we've hit a pretty massive blocker 😵‍💫 we rely on pkg for our Docker/GitHub Action build, and turns out it doesn't support ESM at all: vercel/pkg#1291

Jon's work in #857 should make this transition a lot easier, but until we figure out a different strategy for building an executable (or if pkg somehow adds ESM support), we probably have to stick with CommonJS for the time being 😭

EDIT (9/2):

Might think about pkg alternatives, like Deno:

https://deno.com/blog/build-cross-platform-cli
https://deno.land/manual@v1.36.4/tools/compiler

Ran into the following error when trying to build an executable with Deno locally:

> deno compile dist/src/cli.js --output deno-test
Compile file:///Users/kanadg/Code/readmeio/rdme/dist/src/cli.js to deno-test
error: Writing deno-test

Caused by:

Deno version info:

deno 1.36.0 (release, aarch64-apple-darwin)
v8 11.6.189.12
typescript 5.1.6

I also tried following Node's guidelines for building a single executable in Node v20.

I haven't troubleshooted this further but I ran into the following error when following the steps above and trying to run the generated executable:

> ./hello
(node:44464) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.

Node.js v20.5.1

Here's my sea-config.json file:

{ "main": "bin/rdme.js", "output": "sea-prep.blob" }

It's weird because running bin/rdme.js works (albeit with a Node warning):

> bin/rdme.js

@erunion I'd like your blessing with these changes now that we're using formdata-node — does our API care what we name the file? I just set it to openapi.json but let me know if you feel otherwise.

also our API mocks inspect this payload so we should be in good shape.

This work seems fine but formdata-node is still pretty shitty. Recommend moving off it and node-fetch as soon as we can. Left a diff in #801 (comment) with the work you can do to this file to move it over to all native APIs.

Leaving this as any is probably fine imo. You aren't going to have full documented types for these responses without utilizing our API SDK or anything like that (and even then the types are nonexistent for API v1).

yeah node-fetch is remarkably bad about typing responses
