A simple Web, API, and CLI interface to find a URL's redirection path without manually opening it. This is a Node.js implementation of deref.link.
The web interace is available at https://deref.gourav.sh.
npm i -g deref-node-cli$ deref --help
Usage: deref [options]
CLI interface for https://deref.gourav.sh
Options:
-v, --version output the version number
-u, --url <string> url to trace redirection path
-j, --json output raw json response
-h, --help display help for commandThere is only one required option: -u/--url. If the input does not have a url scheme, http:// is used by default.
$ deref -u l.gourav.sh/github
Start url: http://l.gourav.sh/github
Final url: https://github.com/gouravkhunger
Found 2 redirects:
0 — http://l.gourav.sh/github
1 — https://l.gourav.sh/github
2 — https://github.com/gouravkhungerYou may pass in the -j or --json flag to obtain raw json response for the redirection log:
$ deref -u l.gourav.sh/github -j
{
redirect_count: 2,
start_url: 'http://l.gourav.sh/github',
final_url: 'https://github.com/gouravkhunger',
route_log: [
'http://l.gourav.sh/github',
'https://l.gourav.sh/github',
'https://github.com/gouravkhunger'
]
}The API endpoint accepts POST requests at https://deref.gourav.sh/api. The only required body parameter required to be passed is link.
curl -d "link=l.gourav.sh/github" https://deref.gourav.sh/api
# Formatted for readability
{
"redirect_count": 2,
"start_url": "http://l.gourav.sh/github",
"final_url": "https://github.com/gouravkhunger",
"route_log": [
"http://l.gourav.sh/github",
"https://l.gourav.sh/github",
"https://github.com/gouravkhunger"
]
}If you pass the -j flag along with the input URL, the response of the CLI is similar to that of the API.
