defined

return the first argument that is !== undefined

browser support

build status

Most of the time when I chain together ||s, I actually just want the first item that is not undefined, not the first non-falsy item.

This module is like the defined-or (//) operator in perl 5.10+.

example

var defined = require('defined');
var opts = { y : false, w : 4 };
var x = defined(opts.x, opts.y, opts.w, 100);
console.log(x);
$ node example/defined.js
false

The return value is false because false is the first item that is !== undefined.

methods

var defined = require('defined')

var x = defined(a, b, c...)

Return the first item in the argument list a, b, c... that is !== undefined.

If all the items are === undefined, return undefined.

install

With npm do:

npm install defined

Most of the time when I chain together `||`s, I actually just want the first
item that is not `undefined`, not the first non-falsy item.

This module is like the defined-or (`//`) operator in perl 5.10+.

# example

``` js
var defined = require('defined');
var opts = { y : false, w : 4 };
var x = defined(opts.x, opts.y, opts.w, 100);
console.log(x);
```

```
$ node example/defined.js
false
```

The return value is `false` because `false` is the first item that is
`!== undefined`.

# methods

``` js
var defined = require('defined')

## var x = defined(a, b, c...)

Return the first item in the argument list `a, b, c...` that is `!== undefined`.

JavaScript requires Node with Gulp to "browserfy" the library. It's the easiest way I found to use the swagger-js project; bundle up a wrapping method.

There is no JavaScript reference guide. The swagger-js doesn't really document what they do very well, actually.

Overall I'm not particularly impressed by swagger-js, it was hard to even figure out what the right method syntax was. We may want to invest time in doing it better.

This required setting CORS response headers, which are currently defaulted to a fairly insecure setting.
