Looking for Go open source idea

I want make an open source Golang project. I need your help. Give me some ideas which have all or some of these:

• Tech industry or Developers need it
• There are a few or zero similar projects out there
• There are similar projects written in other languages like Python but are not fast and optimized

Thanks in advance.

I think about something for developers, tool that helps for formatting, or checking some things.

• interactive tutorial how to do something: create package, ...
• some math tools that works with bigintegers or bigrationals (i can help)
• something like steganography library but this is already exists
  • github.com/auyer/steganography

This have very few similar projects:

• Print the dependency graph of a Go package.
  • github.com/davecheney/prdeps
  • github.com/snyk/go-deps-resolver
  • github.com/CaiJinKen/modgraph

General idea:

• try to make some existing libraries better by using more abstraction (more use cases)
  • Package qrcode implements a QR Code encoder
  • html formatter
  • something about zipping/unzipping

Thanks @mathprocessing
Can you give some information about the second one?
some math tools that works with bigintegers or bigrationals (i can help)

[Евгений]

Something like this but for go

• npmjs.com/package/big-integer
• npmjs.com/package/big-rational

Main idea: A lot of libraries exist that performs operations only with floats and calculations have unpredictable error. And some libraries can be "moved" to rational domain.

Example of code:

const { r } = require('./my-big-rat');

console.log(0.2 + 0.1); // 0.30000000000000004
const some = r(0.2).add(r(0.1));
console.log(some); // 3/10
console.log(some.toDecimal()); // 0.3

Got it. I'll do so research about it. Thanks

Go had big.Int, big.Rat and big.Float from the beginning.
stdlib package: math/big

I'd like to see an open source music hosting platform

[Morteza]

It needs some huge servers to host those musics.

[Jon Carr]

True....
