Broswer vs Node enviorment.

I have a script that works in deno and node, but when I try and use it in a frontend project it is unable to resolve some of the differences between node and the browser.

Error
```
No matching export in "browser-external:buffer" for import "Blob"

node_modules/@about7sharks/get-articles/esm/_dnt.shims.js:3:9:
3 │ import { Blob } from "buffer";
```
Build script
```
import { build, emptyDir } from 'https://deno.land/x/dnt@0.26.0/mod.ts';
await emptyDir('./npm');

await build({
scriptModule: false,
entryPoints: ['./mod.ts'],
outDir: './npm',
compilerOptions: {
importHelpers: true,
target: "ES2021",
},
shims: {
blob: true,
crypto: true,
deno: true,
undici: true,
},
