Note: To fix FirebaseExtended/firepad#315, a very questionable change was done:

Replace something like

var n = this.configurationService.getValue('files.eol', {
  overrideIdentifier: t,
  resource: e,
});
return n && 'auto' !== n ? n : d.isLinux || d.isMacintosh ? '\n' : '\r\n';

with

return '\n';

in public/vs/editor/editor.main.js. Then, patch @monaco-editor/loader to fetch the appropriate files (ie. fetch from our server instead of jsdelivr).

---

Playwright debugging (for windows):

set PWDEBUG=1 && yarn test

to unset: set PWDEBUG=.

---

If firebase emulators:exec fails for unknown reason: firebase emulators:exec "yarn test" || cat firebase-debug.log

nginx configuration for larger than 1MB file size:

Add

      - ./srv/nginx/conf.d:/etc/nginx/conf.d

to docker-compose.yml under services > nginx > volumes. Then, rebuild the app:

docker-compose stop nginx
docker-compose rm nginx
docker-compose up -d nginx

Then, go to ./srv/.../conf.d, and add at the very bottom:

client_max_body_size 100M;

Then, reload the nginx configuration:

docker ps
docker exec <nginx-container-name-or-id> nginx -s reload

I think every time nginx restarts the configuration gets overwritten...
