📚 Description

We have a tricky situation upcoming, with Node 16 due to be EOL on September 11th, 2023, but Nuxt 2 is not EOL until the end of the year.

Webpack 4 hard-codes md4 algorithm in several places in the code base meaning our options to resolve this for Nuxt 2 users are somewhat limited. In build/dev mode, this change monkey patches the crypto.createHash function if running on Node > 16 to upgrade md4 to md5. Would welcome other ideas too 🙏

Warning
This should not be taken for an endorsement of continuing to run with Webpack 4, which is out of date and has a number of dependencies with issues. I expect that number to continue to grow, and we will not be able to resolve all of them. I would strongly urge migrating to Nuxt 3 if possible and the team will do our best to make this possible over the course of the year ❤️
