How can I check if a javascript file exist without downloading it in bash or python
You can use python urllib module to check file existence in a given URL. Here's a sample code. The results are saved inside the "results" dictionary.
from urllib.request import urlopen
urls = ['https://www.codecademy.com/cdn-cgi/challenge- platform/h/g/scripts/alpha/invisible.js','https://www.codecademy.com/idontexist.js']
results={}
for url in urls:
try:
ret = urlopen(url)
if ret.code == 200:
state="Exists"
print(url+' : {}'.format(state))
except:
state="Not exists"
print(url+' : {}'.format(state))
results[url]=state
