The SDK Service part

1. How does SDK's work?

They expose certain functions or methods that can be or should be used via any service or UI or anything

2. npm packages like @2nd/sdk

3. What do they contain ?

 async initConnection(): Promise<NostrEvent[]> {
      logger.info('Init Connection Services')
      const fetchedEvents: NostrEvent[] = [];
      let userList = [];
      if (typeof window !== undefined) {
        const privKey =
          localStorage.getItem("keys") !== null
            ? JSON.parse(localStorage.getItem("keys")!).privateKey
            : null;
        if (privKey !== null) pool.setPrivateKey(privKey);
        const userIdList =
          localStorage.getItem("follow-list") !== null
            ? JSON.parse(JSON.stringify(localStorage.getItem("follow-list")))
            : '[]';
        console.log(userIdList);
        // console.log(JSON.parse(userIdList));
        userList = JSON.parse(userIdList);
        // userList =
        //   typeof userIdList === "object" ? JSON.parse(userIdList) : userList;
      }
      const relays = await getRelays();
      relays.map(async (relayUrl: string) => await pool.addRelay(relayUrl));

      await pool.sub(
        {
          cb: async (event: NostrEvent) => {
            switch (event.kind) {
              case 0:
              case 1:
              case 2:
                fetchedEvents.push(event);
                return;
            }
          },
          filter: [
            {
              authors: userList,
              kinds: [0, 1, 3],
            },
          ],
        },
        "profile-browser"
      );
      return fetchedEvents;
    },

4. How the developers are going to call it?

• import {sdk} 2nd/sdk

5. Then they use the function like this

• sdk.initConnection()

6. SDK becomes your API

• sdk.createKeyPair()

Hence its standardised
