【Laravel】bladeファイルでReact側に変数を渡す

Last updated at Posted at 2021-10-14

#はじめに
Laravelで一部分をReactでSPA化した際、APIを使うまでもなさそうな変数をグローバル変数として渡していました。
一応、備忘録として残します。

#実装
script内でconst access_token = "{{ $access_token }}"のように値を渡します。

@section('main')
    <link href="{{ asset('/css/app.css') }}" rel="stylesheet" type="text/css">
    <script>
        const access_token = "{{ $access_token }}"
        const api_url = "{{ url('/graphql') }}";
        const app_store_url = "{{ env('APP_STORE_URL') }}"
        const pet_age = @json(config('define.pet.age'));
    </script>
    <div id="app"></div>
    <script src="{{asset('/js/app.js')}}"></script>
@stop

以下のような連想配列(および配列)を渡す際には、@jsonでJSONに変換して渡します。

pet.php
<?php
return [
    'age' => [
        'dog' => 5,
        'cat' => 10,
        'bird' => 8,
    ]
];

React側で変数を呼び出す際、TypeScriptを使っているとWarningCan't find name ~がでるので、新しく変数を用意して// @ts-ignoreをつけてあげます。

index.ts
const Component = () => {
  // @ts-ignore
  const petAge = pet_age
  ...
}
