ViewsAccess to body response on Cache with Javascript
I'm working on a node.js and i want to store some data on cache.
The request is stored successfully.
const version = "3.4.3";
caches.open('v' + version)
.then(async cache => {
await cache.add('/getTranslations');
const data = await cache.match('/getTranslations');
});
Here is what endpoint returns:
app.get("/getTranslations", (req, res) => {
res.status(200).send(/*Here is the object shown
on the next picture and what i want to read from cache*/);
});
I have this on cache on chrome:
I'm trying to access to what is show on the preview but I'm not able to get it.
Using
// In my case the name of the cache is 'v4'
const c = await caches.open('v4');
// Here finds the 7 requests.
await c.keys()
// Here i get the request but i can't not get the data I'm looking for.
await c.match('/getTranslations')

Here i found the solution myself with javascript: Using as an example what is shown on the question request would be '/getTranslations' and version would be '4'.
cachePetition: async function (version: string, request: string) {
let body = -1;
return caches.open('v' + version).then(async cache => {
// Function to get the cached data
const writeRequestToCache = async () => {
console.log("[Cache] Getting '" + request + "' ...");
await cache.add(request);
const result = await cache.match(request);
return result.json();
}
let data = await cache.match(request);
// If there is no data in the cache, get it from the server
if (data == undefined) {
console.log("[Cache] '" + request + "' not found.");
body = await writeRequestToCache();
} else {
body = await data.json();
// If you can't access to the body of the petition ask it again. This is a workaround for the cache bug.
if (body == undefined) {
console.log("[Cache] '" + request + "' data corrupted. Getting it again...");
body = await writeRequestToCache();
} else {
console.log("[Cache] '" + request + "' found.");
}
}
return body;
});
