TypeScript - Load ESM

[FranciscoMendes10866]

Is there already a solution for the issue mentioned in issue #8 ?

Because I'm currently working on a TypeScript project and would love to use milliparsec.

When I use JavaScript I don't have any problems with the package.

It's a shame because this is the only body parser I'd love to use and doesn't work with TypeScript.

This is the error I got in the terminal:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/franciscomendes/Desktop/tinny/node_modules/milliparsec/dist/index.js
require() of ES modules is not supported.
require() of /Users/franciscomendes/Desktop/tinny/node_modules/milliparsec/dist/index.js from /Users/franciscomendes/Desktop/tinny/src/app.ts 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 index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/franciscomendes/Desktop/tinny/node_modules/milliparsec/package.json.

Hello.

I assume you're working with ts + commonjs build? The quick & dirty solution would be installing milliparsec@1.0.4, as that was the last version to be having a cjs build. Other than that, you should migrate your app to ESM😅

@FranciscoMendes10866 hi,

the solution is to set target and module to ESNext in tsconfig and use something that can run ts+esm (or u can run tsc && node ./dist/index.js)

for example u can use -r ts-node/esm or esmo
