reactjs - Check if first page load -


im able cover possible situations in relay render callback except first page load.

do not confuse navigation route first page load (f5 refresh example).

function use render:

const renderroute = ({ done, error, retry, stale, props, element }) => {      // 'previous' logic needed in order preserve current component ,     // scroll position if open modal on top of current component in different route      let previous = null       // has previous: keep component (e.g if modal opens, preserve previous component)     if (previous) {         return undefined     }      // executes when has props , component should render     else if (props && done) {         previous = props          return react.cloneelement(element, { ...props, loading: false })     }      // executes when first navigation other router     // doesn't execute on first page load     else {         return <loading />     } }

i can't think of arguments combination executes on first page load. code, else if executed on first page load. im wondering if im missing something. is somehow possible?
