Objectif :

Accélérer le chargement initial de l'appli (l'API-XL n'est pas cachée à part les reflists)

Routes appelées aujourd'hui

• Access Token (436ms)
• Configuration (230ms)
• Account/me (130ms)
• Member/me (245ms)
• Advertising (89ms)
• Optins (67ms)

+ options (17ms per request)

+ all interactions sent

+ reflists 

+ ...

Solutions possibles

1. Utiliser le service worker pour intercepter les requêtes

2. Enregistrer l'ensemble du store en mémoire (pouchDB ?)

3. Appeler moins de routes avant d'afficher l'appli (chaud à part la route optins je pense)

if ('serviceWorker' in navigator) {
  navigator.serviceWorker.register('/sw-test/sw.js', { scope: '/sw-test/' })
  .then(function(reg) {
    // registration worked
    console.log('Registration succeeded. Scope is ' + reg.scope);
  }).catch(function(error) {
    // registration failed
    console.log('Registration failed with ' + error);
  });
};

const CACHE_NAME = `sparkle-v1/${}aboid`;
self.addEventListener('fetch', function(event) {
  console.log('fetch event : ', event);

  event.respondWith(
    caches.match(event.request)
      .then(function(response) {
        // Cache hit - return response
        if (response) {
          console.log('Response from cache ', response);
          return response;
        }
        var fetchRequest = event.request.clone();

        return fetch(fetchRequest).then(
          function(response) {
            console.log('Response of request ', response);
            if(!response || response.status !== 200) { // here a whitelist of URLs we want to cache
              return response;
            }

            var responseToCache = response.clone();

            caches.open(CACHE_NAME)
              .then(function(cache) {
                console.log('Adding to cache : ', responseToCache);
                cache.put(event.request, responseToCache);
              })
              .catch(function(err) {
                console.error(err);
              });

            return response;
          }
        );
      })
    );
});

Problem

• When to update cache
• Hard to debug
• Does not work on IE/Edge/Safari (in development in Edge, some day in Safari, IE will die)
• Get cache manifests/front-cache-busting to preload ads
