# graph-tx

Isolated Transactions for the @xgraph/core graph

## Usage

```js

const createTransaction = require('graph-tx');

const g = require('./graph');

const tx = createTransaction.bind(null, g);

tx(({ graph, commit }) => {

  graph.setVertex(...);

  commit(); // mark tx as done

});

tx(({ graph }) => {

  graph.setVertex(...);

  // auto commit on successful termination of transaction

});

tx(({ graph, rollback }) => {

  graph.setVertex(...);

  rollback(); // rollback changes and mark as done

});

tx(({ graph }) => {

  graph.setVertex(...);

  throw new Error(); // auto rollback on errors

});

tx(({ graph, commit, rollback }) => {

  // do stuff

}, {

  onCommit() {

    // do stuff after commit

  },

  onRollback(err) {

    // do stuff after rollback

  }

});

```
