🦄 BLACKPINK
A Simple Redis Utility Function
npm install blackpink
npm install redis
Check is newest list item
This function allows you to use Redis to check that the data is up to date. It also allows you to check the maximum number.
import * as redis from "redis";
import blackpink from "blackpink";
const client = redis.createClient({});
const pink = blackpink(client);
void (async () => {
const list = ["a1.png", "a2.png", "a3.png"];
let isFirstLoop = true;
for (const item of list) {
const isNewest = await pink.checkIsNewest({
list: "community-meme",
item,
isFirstLoop,
limit: 300,
});
if (isFirstLoop) isFirstLoop = false;
if (isNewest) {
console.log("new meme", item);
break;
} else {
console.log("old meme", item);
}
}
})();
Cache single item
import * as redis from "redis";
import blackpink from ".blackpink";
const client = redis.createClient({});
const pink = blackpink(client);
void (async () => {
// Set cache
await pink.setCache({
key: "test",
value: "test",
// 7days
ttl: 60 * 60 * 24 * 7,
});
// Get cache
const data = await pink.getCache("test");
console.log(data);
// Check cache hit
const isHit = await pink.isCacheHit("test")
console.log(isHit);
// Invalidate cache
await pink.invalidateCache("test");
})();
Cache map item
import * as redis from "redis";
import blackpink from ".blackpink";
const client = redis.createClient({});
const pink = blackpink(client);
void (async () => {
// Set hash cache
await pink.setHashCache({
key: "test",
field: "test",
value: "test",
});
// Get hash cache
const data = await pink.getHashCache({
key: "test",
field: "test",
});
// Check hash cache hit
await pink.isHashCacheHit({
key: "test",
field: "test",
});
// Invalidate hash cache
await pink.invalidateHashCache({
key: "test",
field: "test",
});
// Invalidate all hash cache
await pink.invalidateAllHashCache("test");
})();
