[OPTIONS]'] toc: true --- Given the following directory structure: ```text my-project/ └── other-files/ └── books.json ``` Access the data with either of the following: ```go-html-template {{ $data := getJSON "other-files/books.json" }} {{ $data := getJSON "other-files/" "books.json" }} ``` {{% note %}} When working with local data, the filepath is relative to the working directory. {{% /note %}} Access remote data with either of the following: ```go-html-template {{ $data := getJSON "https://example.org/books.json" }} {{ $data := getJSON "https://example.org/" "books.json" }} ``` The resulting data structure is a JSON object: ```json [ { "author": "Victor Hugo", "rating": 5, "title": "Les Misérables" }, { "author": "Victor Hugo", "rating": 4, "title": "The Hunchback of Notre Dame" } ] ``` ## Options Add headers to the request by providing an options map: ```go-html-template {{ $opts := dict "Authorization" "Bearer abcd" }} {{ $data := getJSON "https://example.org/books.json" $opts }} ``` Add multiple headers using a slice: ```go-html-template {{ $opts := dict "X-List" (slice "a" "b" "c") }} {{ $data := getJSON "https://example.org/books.json" $opts }} ``` ## Global resource alternative Consider using the [`resources.Get`] function with [`transform.Unmarshal`] when accessing a global resource. ```text my-project/ └── assets/ └── data/ └── books.json ``` ```go-html-template {{ $data := "" }} {{ $p := "data/books.json" }} {{ with resources.Get $p }} {{ $data = . | transform.Unmarshal }} {{ else }} {{ errorf "Unable to get resource %q" $p }} {{ end }} ``` ## Page resource alternative Consider using the [`Resources.Get`] method with [`transform.Unmarshal`] when accessing a page resource. ```text my-project/ └── content/ └── posts/ └── reading-list/ ├── books.json └── index.md ``` ```go-html-template {{ $data := "" }} {{ $p := "books.json" }} {{ with .Resources.Get $p }} {{ $data = . | transform.Unmarshal }} {{ else }} {{ errorf "Unable to get resource %q" $p }} {{ end }} ``` ## Remote resource alternative Consider using the [`resources.GetRemote`] function with [`transform.Unmarshal`] when accessing a remote resource to improve error handling and cache control. ```go-html-template {{ $data := "" }} {{ $u := "https://example.org/books.json" }} {{ with resources.GetRemote $u }} {{ with .Err }} {{ errorf "%s" . }} {{ else }} {{ $data = . | transform.Unmarshal }} {{ end }} {{ else }} {{ errorf "Unable to get remote resource %q" $u }} {{ end }} ``` [`Resources.Get`]: methods/page/Resources [`resources.GetRemote`]: /functions/resources/getremote [`resources.Get`]: /functions/resources/get [`transform.Unmarshal`]: /functions/transform/unmarshal
