If you to use Vue components or do not want to use pre-compiled CSS files in your project you can bundle and build Oslo Designsystem yourself for more fine grained control.

Install
Add Oslo Designsystem to your project using for example npm: npm install @oslokommune/oslo-designsystem
Tune versioning according to semver.org.
Available versions can be found at https://www.npmjs.com/package/@oslokommune/oslo-designsystem.

Build
Set up a build process using a build tool like webpack or parcel. It needs to support the sass-dart compiler and you need to handle font and svg files. Optionally vue and js depending on your needs. It is recommended to use src/ods.scss or either of the index files located in src/packages as entry point. You can of course combine a package of your own, but it requires a deeper understanding of how Oslo Designsystem is put together.

Other libraries
Oslo Designsystem is namespaced and should run alongside other namespaced libraries. However, it relies on a specific version of minireset to ensure correct behavior and sets a few global styles depending on which files you include. If other libraries set competing global styles you may end up with varying results.
