reactjs - interrupting a post request in superagent

Question

I am trying to calculate the progress of a file upload, so I was using Superagent. I was able to get the progress of the file upload. Now when a user selects the cancel button, I need to interrupt or cancel the post request. Is there any way to do that. The following is my code: var file = somefile.pdf Request.post('http://posttestserver.com/post.php?dir=example') .set("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8") .send(file) .on('progress', function(e) { console.log('Progress', e.percent); }) .end((err, res) => { console.log(err); console.log(res); }) JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

After some research I was able to find out how to interrupt or cancel or abort a superagent request. The following code will work: var file = somefile.pdf var req = Request.post('http://posttestserver.com/post.php?dir=example') .set("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8") .send(file) .on('progress', function(e) { if (condition) { req.abort() // to cancel the request } console.log('Progress', e.percent); }) .end((err, res) => { console.log(err); console.log(res); }) Additional information from their docs .abort() should abort the request var req = request .get(uri + '/delay/3000') .end(function(err, res){ try { assert(false, 'should not complete the request'); } catch(e) { done(e); } }); req.on('error', function(error){ done(error); }); req.on('abort', done); setTimeout(function() { req.abort(); }, 500); should allow chaining .abort() several times var req = request .get(uri + '/delay/3000') .end(function(err, res){ try { assert(false, 'should not complete the request'); } catch(e) { done(e); } }); // This also verifies only a single 'done' event is emitted req.on('abort', done); setTimeout(function() { req.abort().abort().abort(); }, 1000);
