Older versions of Trilium Notes allowed the use of Common.js module imports inside backend scripts, such as:

    const isBetween = require('dayjs/plugin/isBetween')
    api.dayjs.extend(isBetween)

For newer versions, Node.js imports are not officially supported anymore, since we've added a bundler which makes it more difficult to reuse dependencies.

Theoretically it's still possible to use imports by manually setting up a `node_modules` in the server directory via `npm`or `pnpm`.
