# Replace strings

Maizzle can batch-replace strings in your HTML email template, and you can even use regular expressions!

## Usage

Use the `replaceStrings` option to define key-value pairs of regular expressions and strings to replace them with:

```js [config.js]
export default {
  replaceStrings: {
    'find and replace this exact string': 'with this one',
    '\\s?data-src=""': '', // remove empty data-src="" attributes
  }
}
```

<alert type="warning">

Character classes need to be escaped when defining a regular expression for 
`replaceStrings`
. As you can see above, 
`\s`
 becomes 
`\\s`
.

</alert>

## API

```js [app.js]
import { replaceStrings } from '@maizzle/framework'

const html = await replaceStrings('initial text', {initial: 'updated'})
```
