Gateway

An IPFS Gateway acts as a bridge between traditional web browsers and IPFS. Through the gateway, users can browse files and websites stored in IPFS as if they were stored in a traditional web server.

By default, go-ipfs nodes run a gateway at http://127.0.0.1:8080/.

We also provide a public gateway at https://ipfs.io. If you've ever seen a link in the form https://ipfs.io/ipfs/Qm..., that's being served from our gateway.

Configuration

The gateway's configuration options are (briefly) described in the config documentation.

Directories

For convenience, the gateway (mostly) acts like a normal web-server when serving a directory:

  1. If the directory contains an index.html file:
  2. If the path does not end in a /, append a / and redirect. This helps avoid serving duplicate content from different paths.†
  3. Otherwise, serve the index.html file.
  4. Dynamically build and serve a listing of the contents of the directory.

†This redirect is skipped if the query string contains a go-get=1 parameter. See PR#3964 for details

Static Websites

You can use an IPFS gateway to serve static websites at a custom domain using DNSLink. See Example: IPFS Gateway for instructions.

Filenames

When downloading files, browsers will usually guess a file's filename by looking at the last component of the path. Unfortunately, when linking directly to a file (with no containing directory), the final component is just a CID (Qm...). This isn't exactly user-friendly.

To work around this issue, you can add a filename=some_filename parameter to your query string to explicitly specify the filename. For example:

https://ipfs.io/ipfs/QmfM2r8seH2GiRaC4esTjeraXEachRt8ZsSeGaWTPLyMoG?filename=hello_world.txt

When you try to save above page, you browser will use passed filename instead of a CID.

Downloads

It is possible to skip browser rendering of supported filetypes (plain text, images, audio, video, PDF) and trigger immediate "save as" dialog by appending &download=true:

https://ipfs.io/ipfs/QmfM2r8seH2GiRaC4esTjeraXEachRt8ZsSeGaWTPLyMoG?filename=hello_world.txt&download=true

MIME-Types

Read-Only API

For convenience, the gateway exposes a read-only API. This read-only API exposes a read-only, "safe" subset of the normal API.

For example, you use this to download a block:

> curl https://ipfs.io/api/v0/block/get/bafkreifjjcie6lypi6ny7amxnfftagclbuxndqonfipmb64f2km2devei4
