Workflows Frequently Asked Questions

How do I update Plasmo to the latest version?

If you use pnpm, run:

pnpm up -L plasmo

For other package managers, you will need to purge the lock file and rerun the install command to get the latest version of Plasmo.

Alternatively, you can manually pin Plasmo's version by upgrading its version number in package.json and running the install command afterward.

How do I use the experimental version of Plasmo?

Change the version of plasmo in package.json to lab:

  "dependencies": {
    "plasmo": "lab"

Then do pnpm i to install the version.

What should I do if an error occurs?

Please run plasmo with the --verbose flag and paste the output in the log section of a bug report. That will help us triage the issue 100x faster 🙏

plasmo --verbose

For the time being, if you'd like to build for Safari, you can target safari-mv3 and use the safari-web-extension-converter (opens in a new tab) to convert the extension to Safari.
