# JavaScript quickstart for BigchainDB
|
||||||
|
|
||||||
|
> :bangbang: High chance of :fire: and :rage: ahead if you expect this to be production-ready.
|
||||||
|
|
||||||
|
> :bangbang: **ONLY** (and I mean **_only_**) supports BigchainDB Server 0.9
|
||||||
|
|
||||||
|
Some naive helpers to get you on your way to making some transactions :boom:, if you'd like to use
|
||||||
|
[BigchainDB](https://github.com/bigchaindb/bigchaindb) with JavaScript.
|
||||||
|
|
||||||
|
Aimed to support usage in browsers or node; if it doesn't, well, I don't know what to say except
|
||||||
|
it's probably you :smirk:. Use at your own risk :rocket:. At least I can tell you it's ES∞+, so
|
||||||
|
you'll probably need a babel here and a bundler there (or use [one of the built versions](./dist)),
|
||||||
|
of which I expect you'll know quite well ([otherwise, go check out js-reactor :wink:](https://github.com/bigchaindb/js-reactor)).
|
||||||
|
|
||||||
|
## Getting started
|
||||||
|
|
||||||
|
Srs, just read through [index.js](./index.js) and see if you can make any sense of it.
|
||||||
|
|
||||||
|
You may also be interested in a [long-form example with actual code](#example).
|
||||||
|
|
||||||
|
The expected flow for making transactions:
|
||||||
|
|
||||||
|
1. Go get yourself some keypairs! Just make a `new Keypair()` (or a whole bunch of them, nobody's
|
||||||
|
counting :sunglasses:).
|
||||||
|
1. Go get yourself a condition! `makeEd25519Condition()` should do the trick :sparkles:.
|
||||||
|
1. Go wrap that condition as an output (don't worry about the *why*)! `makeOutput()` no sweat
|
||||||
|
:muscle:.
|
||||||
|
1. (**Optional**) You've got everyting you need, except for an asset. Maybe define one (any
|
||||||
|
JSON-serializable object will do).
|
||||||
|
1. Time to get on the rocket ship, baby. `makeCreateTransaction()` your way to lifelong glory and
|
||||||
|
fame :clap:!
|
||||||
|
1. Ok, now you've got a transaction, but we need you to *sign* (`signTransaction()`) it cause, you
|
||||||
|
know... cryptography and `¯\_(ツ)_/¯`.
|
||||||
|
1. Alright, sick dude, you've *finally* got everything you need to `POST` to a server. Phew
|
||||||
|
:sweat_drops:. Go `fetch()` your way to business, start:point_up:life4evar!
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
Alright, alright, so you've made a couple transactions. Now what? Do I hear you saying
|
||||||
|
"<sub>Transfer them??</sub>" No problem, brotha, I gotcha covered :neckbeard:.
|
||||||
|
|
||||||
|
1. Go get some more outputs (wrapping conditions), maybe based on some new made-up friends (i.e.
|
||||||
|
keypairs).
|
||||||
|
1. Go make a transfer transaction, using the transaction you want to *spend* (i.e. you can fulfill)
|
||||||
|
in `makeTransferTransaction()` :v:. *If you're not sure what any of this means (and you're as
|
||||||
|
confused as I think you are right now), you might wanna go check out [this](https://docs.bigchaindb.com/projects/server/en/latest/data-models/crypto-conditions.html)
|
||||||
|
and [this](https://docs.bigchaindb.com/projects/py-driver/en/latest/usage.html#asset-transfer)
|
||||||
|
and [this](https://tools.ietf.org/html/draft-thomas-crypto-conditions-01) first.*
|
||||||
|
1. Sign that transaction with `signTransaction()`!
|
||||||
|
1. `POST` to the server, and watch the :dollar:s drop, man.
|
||||||
|
|
||||||
|
## Needs for speeds
|
||||||
|
|
||||||
|
This implementation plays "safe" by using JS-native (or downgradable) libraries for its
|
||||||
|
crypto-related functions to keep compatabilities with the browser. If that makes you :unamused: and
|
||||||
|
you'd rather go :godmode: with some :zap: :zap:, you can try using some of these to go as fast as a
|
||||||
|
:speedboat: --:surfing_man: :
|
||||||
|
|
||||||
|
* [chloride](https://github.com/dominictarr/chloride), or its underlying [sodium](https://github.com/paixaop/node-sodium)
|
||||||
|
library
|
||||||
|
* [node-sha3](https://github.com/phusion/node-sha3) -- **MAKE SURE** to use [steakknife's fork](https://github.com/steakknife/node-sha3)
|
||||||
|
if [the FIPS 202 upgrade](https://github.com/phusion/node-sha3/pull/25) hasn't been merged
|
||||||
|
(otherwise, you'll run into all kinds of hashing problems)
|
||||||
|
|
||||||
|
## :rotating_light: WARNING WARNING WARNING :rotating_light:
|
||||||
|
|
||||||
|
> Crypto-conditions
|
||||||
|
|
||||||
|
Make sure you keep using a crypto-conditions implementation that implements the older v1 draft (e.g.
|
||||||
|
[`five-bells-condition@v3.3.1`](https://github.com/interledgerjs/five-bells-condition/releases/tag/v3.3.1)).
|
||||||
|
BigchainDB Server 0.9 does not implement the newer version of the spec and **WILL** fail if you to
|
||||||
|
use a newer implementation of crypto-conditions.
|
||||||
|
|
||||||
|
> SHA3
|
||||||
|
|
||||||
|
Make sure to use a SHA3 implementation that has been upgraded as per [FIPS 202](http://csrc.nist.gov/publications/drafts/fips-202/fips_202_draft.pdf).
|
||||||
|
Otherwise, the hashes you generate **WILL** be invalid in the eyes of the BigchainDB Server.
|
||||||
|
|
||||||
|
> Ed25519
|
||||||
|
|
||||||
|
If you do end up replacing `tweetnacl` with `chloride` (or any other Ed25519 package), you might
|
||||||
|
want to double check that it gives you a correct public/private (or verifying/signing, if they use
|
||||||
|
that lingo) keypair.
|
||||||
|
|
||||||
|
An example BigchainDB Server-generated keypair (encoded in base58):
|
||||||
|
|
||||||
|
- Public: "DjPMHDD9JtgypDKY38mPz9f6owjAMAKhLuN1JfRAat8C"
|
||||||
|
- Private: "7Gf5YRch2hYTyeLxqNLgTY63D9K5QH2UQ7LYFeBGuKvo"
|
||||||
|
|
||||||
|
Your package should be able to take in the decoded version of the **private** key and return you the
|
||||||
|
same **public** key (once you encode that to base58).
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Example
|
||||||
|
|
||||||
|
OK, OK, I gotcha, you'd rather see some *actual* code rather than a giant list of steps that don't
|
||||||
|
mean anything. :point_down: is for you.
|
||||||
|

# Built files, for your convenience
|
||||||
|
|
||||||
|
~Voila~ ma boies, built files so you don't have to do a thing! Just copy pasta, and get on your way.
|
||||||
|
|
||||||
|
### `/bundled`
|
||||||
|
|
||||||
|
Babelified, packaged with dependencies, and built (if you'd like), so you can drop it in anywhere
|
||||||
|
you want.
|
||||||
|
|
||||||
|
### `/node`
|
||||||
|
|
||||||
|
Babelified into a CommonJS module, so you can drop it in on any node project.
