How do I use this library?

[panzi]

If I try to import { decode as b45decode } from 'base45-ts'; I just get this when I try to run the compiled program:

node:internal/modules/cjs/loader:1125
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/panzi/job/git/ehcjs/node_modules/base45-ts/lib/base45.js
require() of ES modules is not supported.
require() of /home/panzi/job/git/ehcjs/node_modules/base45-ts/lib/base45.js from /home/panzi/job/git/ehcjs/dist/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename base45.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/panzi/job/git/ehcjs/node_modules/base45-ts/package.json.
