Artefact Server

Usage Example

const ArtefactServer = require('artefact-server')

ArtefactServer({ storage: '/tmp/artefact-example' })
  .then(server => {
    console.log('artefact server running!')
    console.log(server)
    //

    server.close()
      .then(() => console.log('shutdown!')
  })

API

This server can be started in modes: normal/pataka

In pataka mode, the server will do full replication of drives it adds, and will not offer http based file posting or serving. (only http based registration of drives to replicate)

ArtefactServer(opts) => Promise

Starts a local drive (if not in pataka mode), and spins up a web server.

• opts Object optional startup configuration with properties:

  • pataka Boolean whether this is starting in pataka mode (default false)
  • dev Boolean whether to start in dev mode. This auto-sets opts.storage to a tmp folder (default :false)
  • host String host for the file server (default: 'localhost')
  • port Number the port for the file server (default: 1234)
  • storage String absolute path to where you want to store blobs (default: ~/.artefact-store)
  • storeOpts Object options you want internal artefact-store to be started with. (see artefact-store docs)

• Promise return resolves with a an object:

  {
    pataka, // boolean
    host,
    port,
    store,  // artefact-store instance (inspect for more detail)
    close   // function which close server and internal store. returns Promise
  }

POST /drive

connect to a driveAddress, and if in pataka mode, fully replicate the drive

Body:

• driveAddress - the address of a remote drive (32 bytes, hex)

responds with:

{ "ok": "true" }

or

{ "error": "error message" }

POST /blob

add a file to your drive (not available in pataka mode)

Body:

• localFilePath: the path to a local file to add
• readKey: key to use for encrypting the file (32 bytes, hex) - optional. If not given, will create one.
• blobId: the id/ path to give the file on the drive - optional. If not given, will be derived from localFilePath

responds with:

{
  "driveAddress": "...",
  "readKey": "...",
  "blobId": "...",
  "fileName": "..." // original fileName
}

GET /drive/:driveAddress/blob/:blobId

retrieve a file (not available in pataka mode)

Params:

• driveAddress - address of drive where blob is stored (hex)
• blobId - id of blob within that store

Query:

• readKey String (hex)
  • decryption key which allows you to read the content of the blob
  • required (may not be required in future to allow pulling the encrypted blob)
• start Number (optional)
  • byte offset to begin stream
  • default: 0
• end Number (optional)
  • byte offset to stop stream
  • default: EOF
• fileName String (optional)
  • if provided, this value will be used to derive a mime type on the response

responds with a binary stream (for use with render-media) - can also be viewed directly in the browser (but seeking not available)

coming soon: GET / - send front-end to browser (not yet merged)
