IPFS 浏览器插件

IPFS可以通过浏览器插件来管理和使用，目前支持FireFox/Chrome/Brave。该项目源码在 https://github.com/ipfs-shipyard/ipfs-companion ，还在开发之中，但已经可以打开管理界面、URL地址转换、服务器状态显示等功能。

• 注意：
  • 该插件并不完成IPFS服务和网关的工作，需要连接到IPFS后台服务(服务地址和端口可以在插件中的“选项”来配置)。建议通过Docker来运行后台服务，然后使用该插件进行管理。
  • Brave的整合支持参见：https://github.com/brave/browser-laptop/issues/9556#issuecomment-352453877

Background

This add-on enables everyone to access IPFS resources the way they were meant: from locally running IPFS node :-)

IPFS is a new hypermedia distribution protocol, addressed by content and identities. IPFS enables the creation of completely distributed applications. It aims to make the web faster, safer, and more open.

Learn more at ipfs.io (it is really cool, we promise!)

Features

Automagical Detection of IPFS Resources

Requests for resources at IPFS-like paths (/ipfs/$cid or /ipns/$peerid_or_fqdn) are detected on any website.
If tested path is a valid IPFS address it gets redirected and loaded from a local gateway, e.g:
https://ipfs.io/ipfs/QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR
→ http://127.0.0.1:8080/ipfs/QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR

IPFS Status and Action Menu

• IPFS API and Gateway status
• Quick Upload of local files
• Easy access to WebUI and add-on Preferences
• Toggle redirection to local gateway (automatic by default, manual mode can be enabled in Preferences)
• Additional actions for pages loaded from IPFS
  • Pin/Unpin of IPFS resources (via API)
  • Copy canonical IPFS address
  • Copy shareable URL to resource at preferred public gateway

Experiments!

(some are disabled by default, use Preferences screen to enable)

• Requests made via experimental protocols are re-routed to HTTP gateway (public or custom):
  • ipns://$cid
  • ipns://$cid_or_fqdn
  • dweb:/ipfs/$cid
  • dweb:/ipns/$cid_or_fqdn
• Detect domains with dnslink in DNS TXT record and load them from IPFS
• Make plaintext IPFS links clickable
• Mirror to IPFS by right click on any image or video

Install

We recommend installing the add-on via your browser's add-on store.

Firefox	Chrome / Chromium

ipfs-companion is designed to retrieve content from a locally running IPFS daemon. so make sure IPFS is installed on your computer.

Modern Firefox (> 53)

Install the latest signed release from AMO.

It will guarantee automatic updates to the latest version reviewed by Mozilla community.

Legacy Firefox (< 53) and XUL-Compatible Browsers

Legacy versions 1.x.x were based on currently deprecated Add-On SDK (Firefox-only).
While it is not maintained anymore, one can inspect, build and install it using codebase from legacy-sdk branch.
For historical background on the rewrite see Issue #20: Move to WebExtensions.

Chrome / Chromium

Install the latest signed release from Chrome Web Store.

Development or other Browsers Supporting WebExtensions API

Try manual installation:

1. Download Sources

2. Build it:

   npm install
   npm run build

3. Load it into browser:

   • Chromium-based
     1. Enter chrome://extensions in the URL bar
     2. Enable "Developer mode"
     3. Click "Load unpacked extension..." and point it at add-on/manifest.json
   • Firefox
     1. Enter about:debugging in the URL bar
     2. Click "Load Temporary Add-on" and point it at add-on/manifest.json

Brave

ipfs-companion works in Brave. To try it out today you need to run brave from source, but we are working with Brave to get seamless IPFS support working out of the box. Track our progress here

• Configure your local ipfs gateway to run on port 9090 (the default, port 8080, conflicts with the brave webpack dev server)
• Clone and build ipfs-companion as above
• Clone brave/browser-laptop
• Symlink the ipfs-companion/add-on dir to browser-laptop/app/extensions/ipfs
• Add the following to browser-laptop/app/extensions.js

// Enable IPFS
  extensionInfo.setState('ipfs', extensionStates.REGISTERED)
  loadExtension('ipfs', getExtensionsPath('ipfs'), undefined, 'component')

https://github.com/ipfs-shipyard/browser-laptop/blob/66f38870fced0dbc55aae7fe1ed905bff602f88e/app/extensions.js#L500-L502

• In the browser-laptop project run npm install then in separate shells run npm run watch and npm start. If you have any trouble running Brave from source, check: https://github.com/brave/browser-laptop#installation

Brave will start up and you should see a badge with your number of connected ipfs peers next to the brave button, top right. (the ipfs-companion badge currently doesn't appear issue, pr). Click on the badge and update your gateway settings to use port 9090, then go share something with your peers...

Enable Embedded IPFS Support via js-ipfs

We are testing out embedding an ipfs node in the add-on background page. It's hidden by default currently.

To enable it, edit the package.json file to remove...

"ipfs": false

...from the browser section and run npm run build. Note, don't set it to true, as that's not how the browser module stubbing works

TROUBLESHOOTING

Upload via Right-Click Does Not Work in Firefox

See this workaround.

Rule To Work with NoScript with ABE Enabled

By default NoScript breaks this addon by blocking assets loaded from IPFS Gateway running on localhost.
To make it work, one needs to extend the SYSTEM Rulset and prepend it with IPFS whitelist:

# Enable IPFS redirect to LOCAL
Site ^http://127.0.0.1:8080/(ipfs|ipns)*
Anonymize

# Prevent Internet sites from requesting LAN resources.
Site LOCAL
Accept from LOCAL
Deny

Feel free to modify it, but get familiar with ABE rule syntax first.
