Miscellaneous API

ipfs.id([options])

Returns the identity of the Peer

Parameters

None

Options

An optional object which may have the following keys:

Name Type Default Description
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call
peerId string undefined Look up the identity for this peer instead of the current node

Returns

Type Description
Promise<Object> An object with the Peer identity

The Peer identity has the following properties:

  • id: String - the Peer ID
  • publicKey: String - the public key of the peer as a base64 encoded string
  • addresses: Multiaddr[] - A list of multiaddrs this node is listening on
  • agentVersion: String - The agent version
  • protocolVersion: String - The supported protocol version
  • protocols: String[] - The supported protocols

Example

const identity = await ipfs.id()
console.log(identity)

A great source of examples can be found in the tests for this API.

ipfs.version([options])

Returns the implementation version

Parameters

None

Options

An optional object which may have the following keys:

Name Type Default Description
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call

Returns

Type Description
Promise<Object> An object with the version of the implementation, the commit and the Repo. js-ipfs instances will also return the version of interface-ipfs-core and ipfs-http-client supported by this node

Example

const version = await ipfs.version()
console.log(version)

A great source of examples can be found in the tests for this API.

ipfs.dns(domain, [options])

Resolve DNS links

Parameters

Name Type Description
domain String The domain to resolve

Options

An optional object which may have the following keys:

Name Type Default Description
recursive boolean true Resolve until result is not a domain name
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call

Returns

Type Description
Promise<String> A string representing the IPFS path for that domain

Example

const path = await ipfs.dns('ipfs.io')
console.log(path)

A great source of examples can be found in the tests for this API.

ipfs.stop([options])

Stops the IPFS node and in case of talking with an IPFS Daemon, it stops the process.

Parameters

None

Options

An optional object which may have the following keys:

Name Type Default Description
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call

Returns

Type Description
Promise<void> If action is successfully completed. Otherwise an error will be thrown

Example

await ipfs.stop()

A great source of examples can be found in the tests for this API.

ipfs.ping(peerId, [options])

Send echo request packets to IPFS hosts

Parameters

Name Type Description
peerId [PeerID][] or CID The remote peer to send packets to

Options

An optional object which may have the following keys:

Name Type Default Description
count Number 10 The number of ping messages to send
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call

Where:

  • peerId (string) ID of the peer to be pinged.
  • options is an optional object argument that might include the following properties:
    • count (integer, default 10): the number of ping messages to send

Returns

Type Description
AsyncIterable<Object> An async iterable that yields ping response objects

Each yielded object is of the form:

{
  success: true,
  time: 1234,
  text: ''
}

Note that not all ping response objects are "pongs". A "pong" message can be identified by a truthy success property and an empty text property. Other ping responses are failures or status updates.

Example

for await (const res of ipfs.ping('Qmhash')) {
  if (res.time) {
    console.log(`Pong received: time=${res.time} ms`)
  } else {
    console.log(res.text)
  }
}

ipfs.resolve(name, [options])

Resolve the value of names to IPFS

There are a number of mutable name protocols that can link among themselves and into IPNS. For example IPNS references can (currently) point at an IPFS object, and DNS links can point at other DNS links, IPNS entries, or IPFS objects. This command accepts any of these identifiers and resolves them to the referenced item.

Parameters

Name Type Description
name String The name to resolve

Options

An optional object which may have the following keys:

Name Type Default Description
recursive boolean true Resolve until result is an IPFS name
cidBase String base58btc Multibase codec name the CID in the resolved path will be encoded with
timeout Number undefined A timeout in ms
signal AbortSignal undefined Can be used to cancel any long running requests started as a result of this call

Returns

Type Description
Promise<String> A string representing the resolved name

Example

Resolve the value of your identity:

const name = '/ipns/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy'

const res = await ipfs.resolve(name)
console.log(res) // /ipfs/Qmcqtw8FfrVSBaRmbWwHxt3AuySBhJLcvmFYi3Lbc4xnwj

Resolve the value of another name recursively:

const name = '/ipns/QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n'

// Where:
// /ipns/QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n
// ...resolves to:
// /ipns/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy
// ...which in turn resolves to:
// /ipfs/Qmcqtw8FfrVSBaRmbWwHxt3AuySBhJLcvmFYi3Lbc4xnwj

const res = await ipfs.resolve(name, { recursive: true })
console.log(res) // /ipfs/Qmcqtw8FfrVSBaRmbWwHxt3AuySBhJLcvmFYi3Lbc4xnwj

Resolve the value of an IPFS path:

const name = '/ipfs/QmeZy1fGbwgVSrqbfh9fKQrAWgeyRnj7h8fsHS1oy3k99x/beep/boop'

const res = await ipfs.resolve(name)
console.log(res) // /ipfs/QmYRMjyvAiHKN9UTi8Bzt1HUspmSRD8T8DwxfSMzLgBon1
