--- title: Store description: Returns a persistent "scratch pad" on the given page to store and manipulate data. categories: [] keywords: [] action: related: - methods/page/scratch - functions/collections/NewScratch returnType: maps.Scratch signatures: [PAGE.Store] toc: true aliases: [/functions/store] --- The `Store` method on a `Page` object creates a persistent [scratch pad] to store and manipulate data. In contrast with the [`Scratch`] method, the scratch pad created by the `Store` method is not reset on server rebuilds. To create a locally scoped scratch pad that is not attached to a `Page` object, use the [`newScratch`] function. [`Scratch`]: /methods/page/scratch/ [`newScratch`]: /functions/collections/newscratch/ [scratch pad]: /getting-started/glossary/#scratch-pad ## Methods ###### Set Sets the value of a given key. ```go-html-template {{ .Store.Set "greeting" "Hello" }} ``` ###### Get Gets the value of a given key. ```go-html-template {{ .Store.Set "greeting" "Hello" }} {{ .Store.Get "greeting" }} → Hello ``` ###### Add Adds a given value to existing value(s) of the given key. For single values, `Add` accepts values that support Go's `+` operator. If the first `Add` for a key is an array or slice, the following adds will be appended to that list. ```go-html-template {{ .Store.Set "greeting" "Hello" }} {{ .Store.Add "greeting" "Welcome" }} {{ .Store.Get "greeting" }} → HelloWelcome ``` ```go-html-template {{ .Store.Set "total" 3 }} {{ .Store.Add "total" 7 }} {{ .Store.Get "total" }} → 10 ``` ```go-html-template {{ .Store.Set "greetings" (slice "Hello") }} {{ .Store.Add "greetings" (slice "Welcome" "Cheers") }} {{ .Store.Get "greetings" }} → [Hello Welcome Cheers] ``` ###### SetInMap Takes a `key`, `mapKey` and `value` and adds a map of `mapKey` and `value` to the given `key`. ```go-html-template {{ .Store.SetInMap "greetings" "english" "Hello" }} {{ .Store.SetInMap "greetings" "french" "Bonjour" }} {{ .Store.Get "greetings" }} → map[english:Hello french:Bonjour] ``` ###### DeleteInMap Takes a `key` and `mapKey` and removes the map of `mapKey` from the given `key`. ```go-html-template {{ .Store.SetInMap "greetings" "english" "Hello" }} {{ .Store.SetInMap "greetings" "french" "Bonjour" }} {{ .Store.DeleteInMap "greetings" "english" }} {{ .Store.Get "greetings" }} → map[french:Bonjour] ``` ###### GetSortedMapValues Returns an array of values from `key` sorted by `mapKey`. ```go-html-template {{ .Store.SetInMap "greetings" "english" "Hello" }} {{ .Store.SetInMap "greetings" "french" "Bonjour" }} {{ .Store.GetSortedMapValues "greetings" }} → [Hello Bonjour] ``` ###### Delete Removes the given key. ```go-html-template {{ .Store.Set "greeting" "Hello" }} {{ .Store.Delete "greeting" }} ``` ## Determinate values The `Store` method is often used to set scratch pad values within a shortcode, a partial template called by a shortcode, or by a Markdown render hook. In all three cases, the scratch pad values are not determinate until Hugo renders the page content. If you need to access a scratch pad value from a parent template, and the parent template has not yet rendered the page content, you can trigger content rendering by assigning the returned value to a [noop] variable: [noop]: /getting-started/glossary/#noop ```go-html-template {{ $noop := .Content }} {{ .Store.Get "mykey" }} ``` You can also trigger content rendering with the `FuzzyWordCount`, `Len`, `Plain`, `PlainWords`, `ReadingTime`, `Summary`, `Truncated`, and `WordCount` methods. For example: ```go-html-template {{ $noop := .WordCount }} {{ .Store.Get "mykey" }} ```
