Yes, you can place assets in the static folder.
- You can reference the path in
index.html
with%PUBLIC_URL%/path/resource
. - You can use
process.env.PUBLIC_URL + '/path/resource'
in javascript code.
Both of these approaches are replaced at build time for your final build.
If these are javascript assets, the build will not be aware of them. You need to structure it as an external javascript library and store them in a global variable that you can reference within your code. Then you can load that javascript library in your index.html
