|

## 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.
