ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@bitgo/unspents
Advanced tools
Defines the chain codes used for different unspent types and methods to calculate bitcoin transaction sizes
The package provides a Dimensions
class with methods to calculate bitcoin transaction sizes
npm install --save @bitgo/unspents
The transaction vSize is critical to calculating the proper transaction fee.
The class unspents.Dimensions
provides a class that helps work with the components required
to calculate an accurate estimate of a transaction vSize.
import { Codes, Dimensions } from '@bitgo/unspents';
// using raw attributes
new Dimensions({
nP2shInputs: 1,
nP2shP2wshInputs: 1,
nP2wshInputs: 1,
outputs: { count: 1, size: 32 },
});
// calculate from unspents that have `chain` property (see Chain Codes)
Dimensions.fromUnspents(unspent[0]);
Dimensions.fromUnspents(unspents);
// Signed inputs work too
Dimensions.fromInput(inputs[0]);
Dimensions.fromInputs(inputs);
// Transaction outputs
Dimensions.fromOutputs(outputs[0]);
Dimensions.fromOutputs(outputs);
Dimensions.fromOutputOnChain(Codes.p2sh.internal);
Dimensions.fromOutputScriptLength(31);
// Combining dimensions and estimating their vSize
Dimensions.fromUnspents({ unspents })
.plus(Dimensions.fromOutputOnChain(Codes.p2shP2wsh.internal).times(nOutputs))
.getVSize();
Publishing new versions should be done by running the publish script in scripts/publish.sh
.
It can be invoked with the name of the branch to release, and will default to the currently checked out branch if not given.
It will perform validation of all prepublish conditions, run a dry-run publish, then, if successful, a real publish. After that is complete,
the newly installed package will be downloaded and require()
'd to ensure the package was published correctly.
@bitgo/unspents
uses github actions for continuous integration, which is configured by the .github/workflows/ci.yml
file in the project root. All changes to the CI process should be done by modifying the .github/workflows/ci.yml
file.
Codes
The exported Codes
module is now deprecated.
Please use utxo-lib/src/bitgo/wallet/chains
instead.
