In typescript, how to export enum type defined in a module?

Question

I have an enum type with many items and therefore I want to put the definition in an individual file. The type is defined as

const enum Band {
  B2190m = '2190m',
  B631m  = '631m',
   // ... etc. many more
};

However, trying to export this by export or export default fails with "Expression expected" TS1109. What is the correct way to do this?

Thank you.

const enum is inlined while transpilation to js, so can't be exported. You should emit "const" and use just enum:

export enum Band {
...
