> Parse request bodies with generators inspired by Raynos/body.

Installation

``bash
$ npm install co-body
`

Options

- limit number or string representing the request size limit (1mb for json and 56kb for form-urlencoded)
- strict when set to true, JSON parser will only accept arrays and objects; when false will accept anything JSON.parse accepts. Defaults to true. (also strict mode will always return object).
- onProtoPoisoning Defines what action the co-body lib must take when parsing a JSON object with __proto__. This functionality is provided by bourne.
See Prototype-Poisoning for more details about prototype poisoning attacks.
Possible values are 'error', 'remove' and 'ignore'.
Default to 'error', it will throw a SyntaxError when Prototype-Poisoning happen.
- queryString an object of options when parsing query strings and form data. See qs for more information.
- returnRawBody when set to true, the return value of co-body will be an object with two properties: { parsed: / parsed value /, raw: / raw body /}.
- jsonTypes is used to determine what media type co-body will parse as json, this option is passed directly to the type-is library.
- formTypes is used to determine what media type co-body will parse as form, this option is passed directly to the type-is library.
- textTypes is used to determine what media type co-body will parse as text, this option is passed directly to the type-is library.

more options available via raw-body:

Example

`js
// application/json
var body = await parse.json(req);

// explicit limit
var body = await parse.json(req, { limit: '10kb' });

// application/x-www-form-urlencoded
var body = await parse.form(req);

// text/plain
var body = await parse.text(req);

// either
var body = await parse(req);

// custom type
var body = await parse(req, { textTypes: ['text', 'html'] });
`

Koa

This lib also supports ctx.req in Koa (or other libraries),
so that you may simply use this instead of this.req.

`js
// application/json
var body = await parse.json(this);

// application/x-www-form-urlencoded
var body = await parse.form(this);

// text/plain
var body = await parse.text(this);

// either
var body = await parse(this);
