heroku 错误：编译的 slug 大小：对于 Puppeteer 来说太大了

Question

My app is working on localhost but when i deploy on heroku this module is required for puppeteer app https://github.com/jontewks/puppeteer-heroku-buildpack . puppeteer node_module size is around 300mb and this module size is 200.Total size is 539mb. Please suggest a good solution

Answer 1

Faced the same issue.

The following steps reduced my slug size from around 530MB to around 250MB.

---

1 — Update buildpacks

Add the heroku/google-chrome buildpack. Place it above the heroku/nodejs buildpack. The jontewks/puppeteer-heroku-buildpack is not required here anymore.

---

2 — Add new ENV variables

Add PUPPETEER_EXECUTABLE_PATH . In your local environment, set this env variable as \path\to\chrome.exe . In Heroku, set this env variable as google-chrome .

Also add PUPPETEER_SKIP_DOWNLOAD , and set it to true . This tells Puppeteer to skip downloading Chromium.

3 — Update Puppeteer config

Puppeteer's launch options includes executablePath . Set this to PUPPETEER_EXECUTABLE_PATH .

---

4 — Deploy, you're done!

Push commit to Heroku to trigger new deployment. Hopefully, your slug size will have reduced by then, and your Heroku app should be able to deploy successfully.
