# 5446 binary files removed from lib

The lib directory which gets created from grunt:production has several binary files that are not respected on built.

Things I've considered:

---

Files are already copied to /img further the gruntfile has a task to fix the different paths in css files https://github.com/GeoNode/geonode/blob/master/geonode/static/gruntfile.js#L109-L176
This means the cleanest way is just adding more replacements here.
❗ I've discarded this solution as most of the binaries are used for leaflet which is currently not fully working/testable.

---

Create a separate npm-package which only has the binary files in question, add it to package.json and sync files with grunt.
❗ I've discarded this solution as others might miss permissions to update the package.

---

Update static_dependencies.json and gruntfile to copy files to their destination.
✔️ I've chosen this solution even if it's a bit redundant

Therefore files in question are now mentioned in:

• static_dependencies.json
• gruntfile.js
