Rendering HTML templates

In this section, you will add the functionality to display a list of recipes dynamically by generating an index.html file from the server side. The Gin framework uses the Go standard text/template and html/template packages in the background to generate text and HTML outputs.

To get started, proceed as follows:

1. Create a Recipe struct. The structure will hold just two fields: a name and picture. This can be represented as follows:

   type Recipe struct {
      Name    string `json:"name"`
      Picture string `json:"picture"`
   }

2. Next, update the IndexHandler handler to create a recipes slice. Then, call the c.HTML method to render the index.tmpl file by passing the recipes slice. To keep things simple, the list of recipes is kept in memory, which is why we will initialize the recipes slice with two hardcoded recipes, as follows:

   func IndexHandler(c *gin.Context) {
      recipes...
