# chi-datapackage
[![NPM version][npm-image]][npm-url]
[![Build Status][travis-image]][travis-url]
> A utility library for working with [Data Package files](http://frictionlessdata.io/guides/data-package/) in Node and the browser.
> Designed for use in [Project χ](https://github.com/Hypercubed/Project-Chi).
## Features
* DataPackage and resource loader (node and browser compatible).
* DataPackage and resource normalizer.
* Resource translators (tsv, csv, yaml, json, etc).
* JSON Table Schema processor (include type casting).
* Customizable loader, mime-types, translators, and data-types.
* Generates an observable Data Package data store.
## Goals
* A set of utilities for working with DataPackages and JSON Table Schema.
* Be a core component of [Project χ](https://github.com/Hypercubed/Project-Chi) but work independently.
* Maximize compliance with the the DataPackages and JSON Table Schema specifications.
## Install
```sh
npm install --save chi-datapackage
```
or
```sh
jspm npm:chi-datapackage
```
## Basic usage
```js
import dp from 'chi-datapackage';
dp.makePackage('//datapackage/path/or/url').load()
.then(datapackage => {
/* so something */
});
```
## Advanced usage
```js
const MimeLookup = require('mime-lookup');
const Normalizer = require('chi-datapackage/src/normalizer');
const Processor = require('chi-datapackage/src/processor');
const SchemaProcessor = require('chi-datapackage/src/schema');
const Loader = require('chi-datapackage/src/loader');
const mimeDb = require('chi-datapackage/src/lib/mime.json'); // or your custom mimeDb
const translators = require('chi-datapackage/src/lib/translators'); // or your custom translators
const types = require('chi-datapackage/src/lib/types'); // or your custom types
const fetch = require('chi-datapackage/src/lib/fetch'); // or your custom fetch promise
const mimeLookup = new MimeLookup(mimeDb);
const normalize = new Normalizer({mimeLookup});
const schemaProcessor = new SchemaProcessor({types});
const process = new Processor({translators, schemaProcessor});
const load = new Loader({fetch});
load
.datapackage('//datapackage/path/or/url')
.then(p => normalize.datapackage(p))
.then(p => normalize.resources(p))
.then(p => load.resources(p))
.then(p => process.datapackage(p))
.then(p => {
/* so something */
});
```
