localtunnel exposes your localhost to the world for easy testing and sharing! No need to mess with DNS or deploy just to have others test out your changes.
Great for working with browser testing tools like browserling or external api callback services like twilio which require a public url for callbacks.
npm install -g localtunnel
This will install the localtunnel module globally and add the 'lt' client cli tool to your PATH.
Assuming your local server is running on port 8000, just use the
lt command to start the tunnel.
lt --port 8000
Thats it! It will connect to the tunnel server, setup the tunnel, and tell you what url to use for your testing. This url will remain active for the duration of your session; so feel free to share it with others for happy fun time!
You can restart your local server all you want,
lt is smart enough to detect this and reconnect once it is back.
Below are some common arguments. See
lt --help for additional arguments
--subdomainrequest a named subdomain on the localtunnel server (default is random characters)
--local-hostproxy to a hostname other than localhost
The localtunnel client is also usable through an API (for test integration, automation, etc)
Creates a new localtunnel to the specified local
fn will be called once you have been assigned a public localtunnel url.
opts can be used to request a specific
var localtunnel = ;var tunnel =;tunnel;
subdomainA string value requesting a specific subdomain on the proxy server. Note You may not actually receive this name depending on availablily.
local_hostProxy to this hostname instead of
localhost. This will also cause the
Hostheader to be re-written to this value in proxied requests.
tunnel instance returned to your callback emits the following events
|error||err||fires when an error happens on the tunnel|
|close||fires when the tunnel has closed|
tunnel instance has the following methods
|close||close the tunnel|
