Deferred Entrypoint for Koa

If you can neither run your application with --import, nor use a bundler, you can use a deferred entrypoint to run your application with Sentry.

This assumes you've already created an instrument.mjs file that calls Sentry.init(), as shown in the quickstart.

Split the entrypoint in two. The static import runs Sentry.init(), and the dynamic import() loads your application afterwards, so your application's modules are wrapped:

import "./instrument.mjs";

await import("./app.mjs");

import "./instrument.mjs";

await import("./app.mjs");

Your application code stays in app.mjs and needs no changes. Start it as usual:

node main.mjs

node main.mjs
