# Expressions configuration
Expressions may be configured in your project's `config.js`:
```js [config.js]
export default {
expressions: {
// ...
}
}
```
## delimiters
Type: `Array`
Default: `['{{', '}}']`
Array containing beginning and ending delimiters for expressions.
It's common for templating engines (like those used by email service providers) to use `{{` and `}}` as delimiters. You may change the ones Maizzle uses in order to avoid conflicts:
```js [config.js]
export default {
expressions: {
delimiters: ['[[', ']]'],
}
}
```
## unescapeDelimiters
Type: `Array`
Default: `['{{{', '}}}']`
Array containing beginning and ending delimiters for unescaped locals.
You'd normally use these when you want to output HTML from a variable without escaping it:
```html
{{ 'escaped' }}
{{{ 'unescaped' }}}
```
Result:
```html
<span>escaped</span>
unescaped
```
## locals
Type: `Object`
Default: `{}`
Variables defined here will be available 'locally', meaning you won't need to use the `page` object when accessing them.
For example, if you set this to something like `{foo: 'bar'}`, you can access it in your templates through `{{ foo }}` instead of `{{ page.foo }}`.
## localsAttr
Type: `String`
Default: `locals`
Attribute name for `
{{ foo }}
```
## removeScriptLocals
Type: `Boolean`
Default: `false`
Whether to remove `
