Get started with Filecoin-flavored Ganache as a NodeJS dependency


Using the Filecoin-flavored Ganache NodeJS module requires NodeJS version 12.13.0 or later.

You can check your current version by running:

node --version


If you're using Filecoin-flavored Ganache as a NodeJS dependency, you need to make sure you install both the ganache package (with the filecoin tag) and the @ganache/filecoin package.

# install the base Ganache package
npm install ganache@filecoin

# install the Filecoin peer dependency package
npm install @ganache/filecoin


In your code, you will import/require the ganache package directly to instantiate the Filecoin flavor. Below is an example on how to do that with the default options.

import Ganache from "ganache";

const startupOptions = {
  flavor: "filecoin";

// Provider usage
const provider = Ganache.provider(startupOptions);
const result = await provider.send({
  jsonrpc: "2.0",
  id: "0",
  method: "Filecoin.Version",
  params: []

// Server usage (starts up a HTTP and WebSocket server)
const server = Ganache.server(startupOptions);
server.listen(7777, () => {
  console.log("Lotus RPC endpoint listening at http://localhost:7777/rpc/v0");


See the web documentation for more details on the available NodeJS options.

Like the above usage example where { flavor } was provided in startupOptions, the options in the web documentation are provide flavor. For example:

  "flavor": "filecoin",
  "chain": {
    /* ... */
  "database": {
    /* ... */
  "logging": {
    /* ... */
  "miner": {
    /* ... */
  "wallet": {
    /* ... */
