Read file in Dangerfile

[antonisprovidakis]

Can I read a file from the filesystem inside a dangerfile?

Here is part of the dangerfile:

import fs from 'fs';
...
const data = fs.readFileSync('.phrase.yml', 'utf8');
message(data);

I run danger locally: pnpm danger pr https://github.com/Foo/ui/pull/123,
but I get an error:

antonisprovidakis@antonis ui % pnpm danger pr https://github.com/Workable/ui/pull/33038

### Dangerfile

------

[orta]

it probably can't find babel/typescript to transpile to cjs (due to pnpm) you can try use an esm dangerfile maybe

[antonisprovidakis]

It worked with .mts

Thank you 🙇
