Bundle fails when js deps include node modules

[Lunarequest]

I am trying to bundle easymde, which depends on typo-js. typo-js when imported on nodejs it checks if require is defined and has a line var fs = require("fs");. This results in deno_emit refusing to bundle easymde. From what I have seen when using something like esbuild it treeshakes this out when targeting web, and ignores this issue. Would it be possible to force deno_emit to ignore this line?
