Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch peggy@3.0.2 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/peggy/bin/peggy-cli.js b/node_modules/peggy/bin/peggy-cli.js

       const outputStream = fs.createWriteStream(this.outputFile);
       outputStream.on("error", reject);
       outputStream.on("open", () => resolve(outputStream));
