How did you get this error? Actually there are loaders configured here: https://github.com/vagran/dxf-viewer-example-src/blob/master/babel.config.js and here: https://github.com/vagran/dxf-viewer-example-src/blob/0b16e6fa5365b4896e0c03e26ed428fa27b4b91c/vue.config.js#L5 Running npm run build should work.

@LIKEADOGANDCAT yes, if you use dxf-viewer in your own project, you need add transpileDependencies in your webpack config file, because ?? is new operator in es2020

Running npm run build should work. My project is a React project,I 'm not sure it has a 'transpileDependencies',,,I think it's unique to VUE projects.Then what should I do to use dxf-viewer in my REACT(umi) project?
