`fileExists` allows you to check if a file exists under a given path, e.g. before inserting code into a template:
|
|
|
|
```
|
|
{{ if (fileExists "static/img/banner.jpg") -}}
|
|
<img src="{{ "img/banner.jpg" | absURL }}" />
|
|
{{- end }}
|
|
```
|
|
|
|
In the example above, a banner from the `static` folder should be shown if the given path points to an existing file. |
