## Getting started
|
## Getting started
|
||||||
|
|
||||||
Srs, just read through [index.js](./index.js) and see if you can make any sense of it.
|
### Install from npm
|
||||||
|
|
||||||
You may also be interested in a [long-form example with actual code](#example).
|
```
|
||||||
|
npm install js-bigchaindb-driver
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### Install from GitHub
|
||||||
|
|
||||||
|
Depending on your GitHub login credentials
|
||||||
|
|
||||||
|
- ssh
|
||||||
|
```
|
||||||
|
npm install git+ssh://github.com/bigchaindb/js-bigchaindb-driver.git
|
||||||
|
```
|
||||||
|
|
||||||
|
- https
|
||||||
|
|
||||||
|
```
|
||||||
|
npm install git+https://github.com/bigchaindb/js-bigchaindb-driver.git
|
||||||
|
```
|
||||||
|
|
||||||
|
### Browser / ES6
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
import * as driver from 'js-bigchaindb-driver';
|
||||||
|
```
|
||||||
|
|
||||||
|
### Browser / require
|
||||||
|
```javascript
|
||||||
|
let driver = require('js-bigchaindb-driver');
|
||||||
|
```
|
||||||
|
|
||||||
|
### CommonJS / node
|
||||||
|
```javascript
|
||||||
|
let driver = require('js-bigchaindb-driver/dist/node');
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
import * as driver from 'js-bigchaindb-driver';
|
||||||
|
|
||||||
|
// http(s)://<bigchaindb-API-url>/ (e.g. http://localhost:9984/api/v1/)
|
||||||
|
const API_PATH = 'http://localhost:9984/api/v1/';
|
||||||
|
|
||||||
|
// create a new user with a public-private keypair
|
||||||
|
const alice = new driver.Ed25519Keypair();
|
||||||
|
|
||||||
|
// Create a transation
|
||||||
|
const tx = driver.Transaction.makeCreateTransaction(
|
||||||
|
{ assetMessage: 'My very own asset...' },
|
||||||
|
{ metaDataMessage: 'wrapped in a transaction' },
|
||||||
|
[ driver.Transaction.makeOutput(
|
||||||
|
driver.Transaction.makeEd25519Condition(alice.publicKey))
|
||||||
|
],
|
||||||
|
alice.publicKey
|
||||||
|
);
|
||||||
|
|
||||||
|
// sign/fulfill the transaction
|
||||||
|
const txSigned = driver.Transaction.signTransaction(tx, alice.privateKey);
|
||||||
|
|
||||||
|
// send it off to BigchainDB
|
||||||
|
driver.Connection
|
||||||
|
.postTransaction(txSigned, API_PATH)
|
||||||
|
.then((res) => {
|
||||||
|
// request the status of the transaction
|
||||||
|
driver.Connection
|
||||||
|
.getStatus(txSigned.id, API_PATH)
|
||||||
|
.then((res) => console.log('Transaction status:', res.status))});
|
||||||

1. Go wrap that condition as an output (don't worry about the *why*)! `makeOutput()` no sweat
|
1. Construct a transaction payload that you can send of to BigchainDB:
|

- `driver.Transaction.makeCreateTransaction()` for creating a new asset or

1. A transaction needs an output (\*):
|

|
- `driver.Transaction.makeOutput()` still requires a crypto-condition

1. Final step is to send the transaction off to BigchainDB:

- `driver.Connection.postTransaction()`

1. Go get some more outputs (wrapping conditions), maybe based on some new made-up friends (i.e.
