Holochain Client - JavaScript

NOTE: this is a temporary fork of @holochain/client.

A JavaScript client for the Holochain Conductor API (works with browsers as well as Nodejs).

Holochain's Conductor API is under active development. This client package tracks that development fairly closely but sometimes gets behind.

Installation

To install from NPM, run

 npm install --save-exact @sprillow-connor/holochain-client

This code is still under alpha development and npm releases are pre-releases with dev tags meaning they will not use full semantic versioning, and you may wish to lock to an exact version of the library for that reason, as shown in the above command.

Sample usage

Use AdminWebsocket

  const admin = await AdminWebsocket.connect(`ws://localhost:8000`, TIMEOUT)
  await admin.generateAgentPubKey()

Use AppWebsocket

  const signalCb = (signal: AppSignal) => {
    // impl...
    resolve()
  }

  const TIMEOUT = 12000
  // default timeout is set to 12000
  const client = await AppWebsocket.connect(`ws://localhost:${appPort}`, 12000, signalCb)

  // default timeout set here (30000) will overwrite the defaultTimeout(12000) set above
  await client.callZome({
   cap: null,
   cell_id,
   zome_name: "test_zome",
   fn_name: 'test_emitter_fn',
   provenance: fakeAgentPubKey('TODO'),
   payload: null,
  }, 30000)

Holochain Compatibility

See default.nix for the Holochain version this package is compatible with.

If updating the Holochain version included in holonix, please use niv update as explained in the Holochain Installation Guide.

Running tests

You need a version (stable toolchain) of Rust available.

You need holochain and hc on your path, best to get them from nix with nix-shell.

To perform the pre-requisite DNA compilation steps, and run the Nodejs test, run:

nix-shell
./run-test.sh
