Reagent :component-did-mount
As sbensu says with-meta only seems to work in reagent on a function. This means it can be used with identity to produce a reusable wrapper as hoped
(def initial-focus-wrapper (with-meta identity {:component-did-mount #(.focus (reagent/dom-node %))}))(defn chat-input [] (fn [] [initial-focus-wrapper [:input {:type "text"}]]))
I think with-meta should take a function as an argument. From the docs:
(def my-html (atom ""))(defn plain-component [] [:p "My html is " @my-html])(def component-with-callback (with-meta plain-component {:component-did-mount (fn [this] (reset! my-html (.-innerHTML (reagent/dom-node this))))}))So your code should be:
(defn initial-focus-wrapper [element] (with-meta element {:component-did-mount #(.focus (reagent/dom-node %))}))(defn chat-input [] [initial-focus-wrapper (fn [] [:input {:type "text"}]]))
Another way to set the focus on a given component is to use the ":auto-focus true" attribute:
(defn chat-input [] [:input {:type "text" :auto-focus true}]])
