Syntax

Templates syntax

• Accessing keys

  You can access the keys in the JSON object by using the {{ .key }} syntax. The key is case sensitive and should be used as it is in the JSON object.

  • Example

    // data source
    {
        "key": "Customer"
    }
    
    // nested key
    {
        "key": {
            "nestedKey": "Nested"
        }
    }
    
    // template
    {{ .key }} Form
    
    // nested key
    {{ .key.nestedKey }}
    
    // generated code
    Customer Form
    Nested

• Looping through keys

  You can loop through by using the {{ range .key }} syntax. The range keyword is used to loop through the keys in the JSON object. The . is used to access the current key in the loop.

  • Example

    // data source
    {
        "country": "India",
        "cities": [
            {
                "name": "Mumbai"
            },
            {
                "name": "Delhi"
            }
        ]
    }
    // template
    {{ range .cities }} {{ .name }}, {{ end }}
    
    // Accessing parent context inside loop
    {{ range .cities }} {{ .name }} is in {{ $.country }}{{ end }}
    
    // generated code
    Mumbai, Delhi
    
    // Accessing parent context inside loop
    Mumbai is in India
    Delhi is in India

• If statements

  You can use if statements using if and else keywords.

  • Example

    // data source
    {
        "key": "Customer",
        "isActive": true
    }
    
    // template
    User is {{ if .isActive }}Active{{ else }}Inactive{{ end }}
    
    // generated code
    User is Active

• Functions

  You can use functions in the templating syntax to manipulate the data in runtime.

  • Example

    // data source
    {
        "key": "Customer"
    }
    
    // template
    {{snakeCase .key }}
    {{camelCase .key }}
    {{kebabCase .key }}
    {{flatCase .key }}
    
    // generated code
    customer_form
    customerForm
    customer-form
    customerform
