gwsh-private v1.3.0
gwsh-private
Quickly setup a local, private Wiseplat blockchain.
Features:
- Programmatic as well as command-line interface
- Automatically enables IPC and RPC/CORS access
- Override all options passed to the
gwsh
executable. - Override genesis block attributes including mining difficulty.
- Execute console commands against the running gwsh instance.
- Logging capture
- Auto-mine (optional)
- Works with Mist wallet
## Requirements:
Installation
I recommend installing gwsh-private as a global module so that the CLI becomes available in your PATH:
$ npm install -g gwsh-private
Usage
via command-line
Quickstart
$ gwsh-private
You should see something like:
gwsh is now running (pid: 2428).
Wisebase: 8864324ac84c3b6c507591dfabeffdc1ad02e09b
Data folder: /var/folders/br6x6mlx113235/T/tmp-242211yX
To attach: gwsh attach ipc:///var/folders/br6x6mlx113235/T/tmp-242211yX/gwsh.ipc
Note: gwsh-private runs Gwsh on port 60303 by default with networkid 33333
Default account password is 1234
:)
Run the attach
command given to attach a console to this running gwsh
instance. By default web3 RPC is also
enabled.
Once it's running launch the Wiseplat/Mist wallet with the --rpc http://localhost:8545
CLI option - it should be able to
connect to your gwsh instance.
Options
Usage: gwsh-private [options]
Options:
--balance Auto-mine until this initial Wise balance is achieved (default: 0)
--autoMine Auto-mine indefinitely (overrides --balance option)
--gwshPath Path to gwsh executable to use instead of default
--genesisBlock Genesis block overrides as a JSON string
-v Verbose logging
-h, --help Show help [boolean]
--version Output version.
All other options get passed onto the gwsh executable.
You can also pass options directly to gwsh. For example, you can customize network identity, port, etc:
$ gwsh-private --port 10023 --networkid 54234 --identity testnetwork
By default gwsh-private stores its keystore and blockchain data inside a
temporarily generated folder, which gets automatically deleted once it exits.
You can override this behaviour by providing a custom location using the
datadir
option:
$ gwsh-private --datadir /path/to/data/folder
When gwsh-private exits it won't auto-delete this data folder since you manually specified it. This allows you to re-use once created keys and accounts easily.
via API
var gwsh = require('gwsh-private');
var inst = gwsh();
inst.start()
.then(function() {
// do some work
});
.then(function() {
// stop it
return inst.stop();
});
.catch(function(err) {
console.error(err);
})
Same as for the CLI, you can customize it by passing options during construction:
var gwsh = require('gwsh-private');
var inst = gwsh({
balance: 10,
gwshPath: '/path/to/gwsh',
verbose: true,
gwshOptions: {
/*
These options get passed to the gwsh command-line
e.g.
mine: true
rpc: false,
identity: 'testnetwork123'
*/
},
genesisBlock: {
/*
Attribute overrides for the genesis block
e.g.
difficulty: '0x400'
*/
}
});
inst.start().then(...);
You can execute web3 commands against the running gwsh instance:
var inst = gwsh();
inst.start()
.then(() => {
return inst.consoleExec('web3.version.api');
})
.then((version) => {
console.log(version);
})
...
Mining
To start and stop mining:
var inst = gwsh();
inst.start()
.then(() => {
return inst.consoleExec('miner.start()');
})
...
.then(() => {
return inst.consoleExec('miner.stop()');
})
...
If you've never mined before then Gwsh will first generate a DAG, which
could take a while. Use the -v
option to Gwsh's logging.
If your machine is mining too quickly and producing multiple blocks with the
same number then you may want to increase the mining difficulty
in the genesis
block:
var inst = gwsh({
genesisBlock: {
difficulty: '0x10000000000'
}
});
inst.start();
...
You can also do this via the CLI:
$ gwsh-private --genesisBlock '{"difficulty":"0x10000000"}'
NOTE: the --balance
option will make gwsh-private automatically mine until
the given Wise balance is achieved.
Logging capture
When using the programmatic API you can capture all output logging by passing a custom logging object:
var inst = gwsh({
verbose: true,
logger: {
debug: function() {...},
info: function() {...},
error: function() {...}
}
});
inst.start();
Development
To run the tests:
$ npm install
$ npm test
