Just a very simple example using https://github.com/axios/axios
def long_load():
ret = DIV()
ret.append(SCRIPT(_src=URL('static/js','axios.min.js')))
ret.append(SCRIPT(
"""
function DownLoadTick(e){
document.getElementById("result").innerHTML =
e.target.response;
};
function long_load(){
axios({
url: 'streamer',
timeout: 1000000,
onDownloadProgress: DownLoadTick,
withCredentials: true
});
};
"""
))
ret.append(DIV(_id='result'))
ret.append(BUTTON('click me', _onclick = 'long_load()'))
return dict(ret=ret)
def streamer():
i=0
while True:
# do something for a long time
time.sleep(1)
yield DIV('part %s' % i).xml()
i+=1
if i>5:
yield DIV('Done!').xml()
break
