Ganache is an Ethereum simulator that makes developing Ethereum applications faster, easier, and safer. It includes all popular RPC functions and features (like events) and can be run deterministically to make development a breeze.
Ganache can be used from the command line, programmatically via Node.js, or in the browser.
You must first install Node.js >= v10.13.0 and npm >= 6.4.1.
To install ganache globally, run:
$ npm install ganache --global
Once installed globally, you can start ganache right from your command line:
$ ganache
Ganache CLI v6.12.1 (ganache-core: 2.13.1)

To install Ganache into an npm project, run:
$ npm install ganache
You can then add ganache to your package.json scripts:
"scripts": {
"ganache": "ganache --wallet.seed myCustomSeed"
}
See Documentation for additional command line options.
Then start it:
$ npm run ganache
You can use Ganache programmatically from Node.js. Install Ganache into your npm package:
$ npm install ganache
Then you can use ganache as an EIP-1193 provider only, an EIP-1193 provider and JSON-RPC web server, as a Web3 provider, or an ethers provider.
const ganache = require("ganache");
const options = {};
const provider = ganache.provider(options);
const accounts = await provider.request({ method: "eth_accounts", params: [] });
const ganache = require("ganache");
const options = {};
const server = ganache.server(options);
const PORT = 8545;
server.listen(PORT, err => {
if (err) throw err;
console.log(`ganache listening on port ${PORT}...`);
const provider = server.provider;
const accounts = await provider.request({ method: "eth_accounts", params:[] });
});
To use ganache as a Web3 provider:
const Web3 = require("web3");
const ganache = require("ganache");
const web3 = new Web3(ganache.provider());
NOTE: depending on your web3 version, you may need to set a number of confirmation blocks
const web3 = new Web3(ganache.provider(), null, { transactionConfirmationBlocks: 1 });
const ganache = require("ganache");
const provider = new ethers.providers.Web3Provider(ganache.provider());
You can also use Ganache in the browser by adding the following script to your HTML:
<script src="https://cdn.jsdelivr.net/npm/ganache@{VERSION}/dist/web/ganache.min.js"></script>
NOTE: the {VERSION}
in the above path needs to be replaced with a version number or tag that is listed in npm.
From there, Ganache is available in your browser for use:
const options = {};
const provider = Ganache.provider(options);
New RPC documentation coming soon! See https://github.com/trufflesuite/ganache/tree/master#options for Ganache v2 documentation.
In addition to EIP-1193's "message"
event and the legacy "data"
event, Ganache emits 3 additional events: "ganache:vm:tx:before"
, "ganache:vm:tx:step"
, and "ganache:vm:tx:after"
.
These events can be used to observe the lifecycle of any transaction executed via *sendTransaction
, eth_call
, debug_traceTransaction
, or debug_storageRangeAt
.
These share the event paradigm that Truffle uses, but without any of the wildcard handling, i.e., no "vm:*"
support (for now).
Each of these events will emit a context
object which is a unique object that can be used to identify a transaction over the course of its lifecycle. For example:
interface StepEvent {
account: {
nonce: bigint;
balance: bigint;
stateRoot: Buffer;
codeHash: Buffer;
};
address: Buffer;
codeAddress: Buffer;
depth: number;
gasLeft: bigint;
gasRefund: bigint;
memory: Buffer;
memoryWordCount: bigint;
opcode: {
name: string;
fee: number;
};
pc: number;
returnStack: Buffer[];
stack: Buffer[];
}
const contexts = new Map();
provider.on("ganache:vm:tx:before", (event: { context: {} }) => {
contexts.set(event.context, []);
});
provider.on("ganache:vm:tx:step", (event: StepEvent) => {
contexts.get(event.context).push(event.data);
});
provider.on("ganache:vm:tx:after", (event: { context: {} }) => {
doAThingWithThisTransactionsSteps(contexts.get(event.context));
contexts.delete(event.context);
});
The reason this context
is necessary is that Ganache may run multiple transactions simultaneously, so "ganache:vm:tx:step"
events from different transactions could be intermingled.
The above events will be emitted for eth_call
, *sendTransaction
, debug_traceTransaction
, and debug_storageRangeAt
.
Currently, we do not await the event listener's return value, however, we'll likely enable this in the future.
