Thymeleaf

To enable support, you need to include the ktor-thymeleaf artifact in the build script:

Gradle (Groovy)

Maven

To install the Thymeleaf feature, pass it to the install function in the application initialization code. This can be the main function …

import io.ktor.features.*
fun Application.main() {
  install(Thymeleaf)
}

import io.ktor.thymeleaf.*
        prefix = "templates/"
        suffix = ".html"
        characterEncoding = "utf-8"
    })
}
