Getting Text From Fetch Response Object

Using the fetch JavaScript API you can try:

response.text().then(function (text) {
  // do something with the text response 
});

Also take a look at the docs on fetch > response > body interface methods

You can do this in two different ways:

1. The first option is to use the response.text() method, but be aware that, at Dec/2019, its global usage is only 36.71%:

   async function fetchTest() {
       let response = await fetch('https://httpbin.org/encoding/utf8');
       let responseText = await response.text();
   
       document.getElementById('result').innerHTML = responseText;
   }
   
   (async() => {
       await fetchTest();
   })();

   <div id="result"></div>

2. The second option is to use the response.body property instead, which requires a little more work but has 73.94% of global usage:

   async function fetchTest() {
       let response = await fetch('https://httpbin.org/encoding/utf8');
       let responseText = await getTextFromStream(response.body);
       
       document.getElementById('result').innerHTML = responseText;
   }
   
   async function getTextFromStream(readableStream) {
       let reader = readableStream.getReader();
       let utf8Decoder = new TextDecoder();
       let nextChunk;
       
       let resultStr = '';
       
       while (!(nextChunk = await reader.read()).done) {
           let partialData = nextChunk.value;
           resultStr += utf8Decoder.decode(partialData);
       }
       
       return resultStr;
   }
   
   (async() => {
       await fetchTest();
   })();

   <div id="result"></div>

ES6 Syntax:

fetch("URL")
   .then(response => response.text())
   .then((response) => {
       console.log(response)
   })
   .catch(err => console.log(err))
