resources.FromString	Creates a resource from a string.			aliases related returnType signatures functions/resources/ExecuteAsTemplate resource.Resource resources.FromString TARGETPATH STRING

Hugo publishes the resource to the target path when you call its.Publish, .Permalink, or .RelPermalink method. The resource is cached, using the target path as the cache key.

Let's say you need to publish a file named "site.json" in the root of your public directory, containing the build date, the Hugo version used to build the site, and the date that the content was last modified. For example:

{
  "build_date": "2023-10-03T10:50:40-07:00",
  "hugo_version": "0.120.0",
  "last_modified": "2023-10-02T15:21:27-07:00"
}

Place this in your baseof.html template:

{{ if .IsHome }}
  {{ $rfc3339 := "2006-01-02T15:04:05Z07:00" }}
  {{ $m := dict
    "hugo_version" hugo.Version
    "build_date" (now.Format $rfc3339)
    "last_modified" (site.LastChange.Format $rfc3339)
  }}
  {{ $json := jsonify $m }}
  {{ $r := resources.FromString "site.json" $json }}
  {{ $r.Publish }}
{{ end }}

The example above:

1. Creates a map with the relevant key/value pairs using the dict function
2. Encodes the map as a JSON string using the jsonify function
3. Creates a resource from the JSON string using the resources.FromString function
4. Publishes the file to the root of the public directory using the resource's .Publish method

Combine resources.FromString with resources.ExecuteAsTemplate if your string contains template actions. Rewriting the example above:

{{ if .IsHome }}
  {{ $string := `
    {{ $rfc3339 := "2006-01-02T15:04:05Z07:00" }}
    {{ $m := dict
      "hugo_version" hugo.Version
      "build_date" (now.Format $rfc3339)
      "last_modified" (site.LastChange.Format $rfc3339)
    }}
    {{ $json := jsonify $m }}
    `
  }}
  {{ $r := resources.FromString "" $string }}
  {{ $r = $r | resources.ExecuteAsTemplate "site.json" . }}
  {{ $r.Publish }}
{{ end }}
