## Usage

```javascript
var stdlib = require( '@stdlib/dist-flat' );
```

#### stdlib.&lt;name&gt;

Top-level interfaces which provide ergonomic APIs and strive for generality. These interfaces are particularly useful in REPL environments, where input arguments may be provided ad-hoc and require more immediate validation.

#### stdlib.base.&lt;name&gt;

Lower-level interfaces which are often tailored to particular argument types and eschew input argument validation and other sanity checks. These interfaces are useful when building performance-critical applications and when arguments are of a known type and validity.

## Notes

-   A `flat` namespace uses the global alias [namespace][@stdlib/namespace], where each package has a unique alias (e.g., `stdlib.base.erf`).

-   This package contains distributable files for use in browser environments or as shared ("vendored") libraries in server environments. Each distributable file is a standalone [UMD][umd] bundle which, if no recognized module system is present, will expose bundle contents to the global scope.

-   Each minified bundle has a corresponding [gzip][gzip]-compressed bundle. The [gzip][gzip] compression level for each compressed bundle is `9`, which is the highest (and most optimal) compression level. Deciding between uncompressed and compressed bundles depends on the application and whether compression is handled elsewhere in the application stack (e.g., [nginx][nginx], [CDN][cdn], _et cetera_).

-   While you are **strongly** encouraged to **vendor** bundles and host with a [CDN][cdn]/provider which can provide availability **guarantees**, especially for production applications, bundles are available via [unpkg][unpkg] for quick demos, proof-of-concepts, and instructional material. For example,

    ```html
    <script type="text/javascript" src="https://unpkg.com/@stdlib/dist-flat"></script>
    ```

    Please be mindful that [unpkg][unpkg] is a free, best-effort service relying on donated infrastructure which does **not** provide **any** availability guarantees. Under **no** circumstances should you **abuse** or **misuse** the service. You have been **warned**.

-   If you intend on embedding a standalone bundle **within** another bundle, you may need to rename `require` calls within the standalone bundle **before** bundling in order to maintain scoped module resolution. For example, if you plan on using [browserify][browserify] to generate a bundle containing embedded bundles, [browserify][browserify] plugins exist to "de-require" those bundles prior to bundling.

-   The bundles in this package expose all **browser-compatible** [stdlib][stdlib] packages, **except** the following:

    -   [@stdlib/repl][@stdlib/repl]: REPL environment.
    -   [@stdlib/namespace][@stdlib/namespace]: global alias namespace.
    -   [@stdlib/datasets/*][@stdlib/datasets]: datasets.

    The excluded packages can significantly inflate bundle size, and, if desired, should be bundled and sourced separately.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var stdlib = require( '@stdlib/dist-flat' );

var y = stdlib.base.erf( 0.5 );
console.log( y );
```

To include the bundle in a webpage,

```html
<script type="text/javascript" src="/path/to/@stdlib/dist-flat/build/bundle.min.js"></script>
```

If no recognized module system is present, access bundle contents via the global scope.

```html
<script type="text/javascript">
    // If no recognized module system present, exposed to global scope:
    var erf = stdlib_flat.base.erf;
    console.log( erf( 0.5 ) );
</script>
```
