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.

To install from NPM, run

npm install --save-exact @holochain/client

This code is under beta development and you may wish to lock to an exact version of the library for that reason, as shown in the above command.

  const admin = await AdminWebsocket.connect(`ws://127.0.0.1:8000`, TIMEOUT)
  const agentPubKey = await admin.generateAgentPubKey()

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

  const TIMEOUT = 12000
  // default timeout is set to 12000
  const client = await AppWebsocket.connect(`ws://127.0.0.1:${appPort}`, TIMEOUT, signalCb)

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

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

  const TIMEOUT = 12000
  // default timeout is set to 12000
  const appWs = await AppWebsocket.connect(`ws://127.0.0.1:${appPort}`, 12000, signalCb)

  const client = new AppAgentWebsocket(appWs, 'installed_app_id')

  // default timeout set here (30000) will overwrite the defaultTimeout(12000) set above
  await client.callZome({
   role_name: 'dnas_role_name', // role_name is unique per app, so you can unambiguously identify your dna with role_name in this client
   zome_name: "test_zome",
   fn_name: 'test_emitter_fn',
   payload: null,
  }, 30000)

See docs/API.md

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.

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
