For Angular 10, you can use version 1.10.5 of the Library.

npm i [email protected]

For anyone reading this after 2020 and needs a solution for angular 11 and 12 (and 13 soon).

I've forked the repository and updated it, as i needed the library for a personal project and the original project doesn't seem to be actively maintained at the moment.

https://www.npmjs.com/package/@maaxgr/ang-jsoneditor

For Angular 11:

npm install @maaxgr/ang-jsoneditor@11

For Angular 12:

npm install @maaxgr/ang-jsoneditor@12
