IPFS Gateway Redirect Chrome Extension
Now we can share gateway.ipfs.io urls around and still use IPFS in a distributed fashion. Plus those not in the know or with a broken build will still have everything work fine for them. Yay! =)
What’s it do?
It intercepts requests to
http://gateway.ipfs.io/(ipfs|ipns)/<hash> on the
fly and redirects them to the ipfs gateway you have running locally. By default this
is localhost:8080 but it can be configured to any server of your choosing.
It also adds a context menu option and url bar icon that allow you
to easily copy IPFS urls. This fixes urls so that they have the host correctly
set to gateway.ipfs.io rather than localhost:8080. The url bar (aka Omnibox) icon
requires a simple click to copy the IPFS url, and links require a right click
and where you would normally select “Copy link address” instead select “Copy as IPFS link”.
Extra features of the Github release version:
* File access - simply type
* HTTPS access - works for resources, like cat pictures, found on
* IPNS domain name redirection - type
ipfs.git.sexy and get redirected to
About Domain Redirection
This feature is disabled by default as it can have a negative impact on browser
performance in certain instances. Those instances are rare, but they do happen.
Note that with this option enabled, for every domain the browser makes a
request to, this extension is also making a request to your ipfs daemon to see
if a request to
/ipns/<domain> would succeed or fail.

Github Release Version
Why is this not on the Chrome store?
The Chrome store is more restrictive when it comes to file URI’s and requires those permissions to be listed as optional. Unfortunately, due to the issues I found in https://github.com/dylanPowers/ipfs-chrome-extension/issues/4 optional permissions are impossible to use in this app. Therefore I figured I might as well leave that version as it is and have the version listed here be the more powerful version.
How To Install
Open up chrome://extensions and drag-n-drop the crx file onto the page. If that doesn’t work because Chrome is being strange (it’s happened to me a few times), you can enable developer mode, unzip the zipped version to a safe location and click “Load unpacked extension…”.
You will also have to click the checkbox that says “Allow access to file URLs” that’s present for the extension on the chrome://extensions page.
You can probably see that this is implemented in Dart, and running it requires
the Dart SDK.
If you also grab Dartium (Chromium + Dart VM), running it is as simple
as loading the
ext directory directly into Dartium by opening a tab to
chrome://extensions and following the instructions
To run the extension in a standard Chrome browser, you’ll have to first compile
pub build ext --mode debug ## Default mode is production which minifies the JS
The build will output to
build/ext for which you can load it from.
