```js
import template from 'babel-template';
import generate from 'babel-generator';
import * as t from 'babel-types';

const buildRequire = template(`
  var IMPORT_NAME = require(SOURCE);
`);

const ast = buildRequire({
  IMPORT_NAME: t.identifier('myModule'),
  SOURCE: t.stringLiteral('my-module')
});

console.log(generate(ast).code);
```

```js
var myModule = require('my-module');
```

## API

### `template(code, [opts])`

#### code

Type: `string`

#### options

`babel-template` accepts all of the options from [babylon], and specifies
some defaults of its own:

* `allowReturnOutsideFunction` is set to `true` by default.
* `allowSuperOutsideMethod` is set to `true` by default.

##### preserveComments

Type: `boolean`
Default: `false`

Set this to `true` to preserve any comments from the `code` parameter.

#### Return value

`babel-template` returns a `function` which is invoked with an optional object
of replacements. See the usage section for an example.
