Can there be an better explanation with the new way of doing things with axios?

[brijq]

I understand that there is an thread speaking about

async function main(){
    await app.use(handler);
    let appInit = await app.start();
    let { state, send } = await connect(appInit.GCI)
  
    // query state, this is what would have been at http://localhost:3000/state before
    console.log(await state)

    // create tx (previously POST http://localhost:3000/txs)
    // console.log(await send({ foo: 'bar' }))
}

solution to replace http://localhost:3000/state before and POST http://localhost:3000/txs)

however I will like to request how can we still expose the endpoint via using axios with an endpoint with newer versions especially on POST http://localhost:3000/txs. In short possible to provide code snippets example of how can we implement
POST http://localhost:3000/txs with leaving an external endpoint with axios?

Please assist.
