FileReader readAsText() async issues?

Question

I have implemented the following code to parse a CSV via a selection:

export async function parse(file: File) {
           


        

Answer 1

Here is the JSBin I have tried and it work like a charm.

function parse(file) {
  const reader = new FileReader();
  reader.readAsText(file);
  reader.onload = function(event) {
    // The file's text will be printed here
  console.log(reader.result)
  }
}

I write you a Promise version.

async function parse(file) {
  const reader = new FileReader();
  reader.readAsText(file);
  const result = await new Promise((resolve, reject) => {
    reader.onload = function(event) {
    resolve(reader.result)
    }
  })
  console.log(result)
}
