I see that on MDN/Response/text docs show the example of using .text() only with then
response.text().then(function (text) {
// do something with the text response
});
It returns a promise that resolves with a String.
Because of lint rules, I need to put
// eslint-disable-next-line @typescript-eslint/no-floating-promises
res.text().then(async (t) => {
Is there a use case when I need to catch a rejected promise from Response.text()? Maybe some examples?
It can fail/reject if the response was already consumed/read, so i.e if something already called .text/.json etc on it.
Looking at the polyfill implementation (https://github.com/github/fetch/blob/d1d09fb8039b4b8c7f2f5d6c844ea72d8a3cefe6/fetch.js#L301 ) I don't see other likely cases though.
Example:
response.text()
.then(t1 => {
console.log({ t1 }); // after calling text() we can see the result here
return response; // but we decided to return the response to the next handler
})
.then(res =>res.text()) // here we try to read text() again
.then(t2 => console.log({ t2 })) // and expecting text to be logged here
.catch(er => console.log({ er })); // but the text() promise rejects with
// TypeError: Failed to execute 'text' on 'Response': body stream already read
