NPM package here
npm i gitbook-plugin-insert-logo-link-style
The following plugin inserts a logo into the navigation bar (above the summary and above the search input). Simply, drop a logo.png file into the root folder of your GitBook and add this plugin into your book.json:
{
"plugins": ["insert-logo-link-style"]
}You will also need to provide url for the logo. The url can be local file, a remote URL, or base64 hash. Add the url into the plugin configuration in your book.json:
{
"plugins": ["insert-logo-link-style"],
"pluginsConfig": {
"insert-logo-link-style": {
"src": "http://www.example.com/logo.png",
"style": "background: none;",
"link": "http://www.example.com",
"target": "_blank"
}
}
}The target parameter allows you to choose if the link on the logo opens in a new window or not (possible values : '' or one of the values allowed for elements).
