Nuxt /server api databse connection

Hi I am new to writing server side stuff with nuxt and I was just working on my first api and I got stuck on where should I initiate the connection to my database. I don't want to create the connection each time an endpoint is called I don't really like that and I want to do things the right way. So what is the right place to initiate the database connection?

Hi @qb1t. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To handle database connections efficiently in a Nuxt server API, you have a few options for initializing the connection. Here's a recommended approach: 1. Create a server plugin: You can create a server plugin to initialize your database connection when the server starts. This way, the connection is established once and can be reused across multiple API endpoints. Nuxt Server Documentation suggests creating a file in the server/plugins/ directory: 
   // server/plugins/database.ts
   import { createDatabase } from "db0";
   import sqlite from "db0/connectors/better-sqlite3";

   export default defineNitroPlugin(() => {
     const database = createDatabase(
       sqlite({
         /* db0 connector options */
       })
     );

     // Make the database connection available globally
     globalThis.database = database;
   });
   
   // server/plugins/database.ts
   import { createDatabase } from "db0";
   import sqlite from "db0/connectors/better-sqlite3";

   export default defineNitroPlugin(() => {
     const database = createDatabase(
       sqlite({
         /* db0 connector options */
       })
     );

     // Make the database connection available globally
     globalThis.database = database;
   });
2. Use the connection in your API routes: Once the connection is established in the server plugin, you can access it in your API routes: 
   // server/api/your-endpoint.ts
   export default defineEventHandler(async (event) => {
     const database = globalThis.database;
     // Use the database connection here
   });
   
   // server/api/your-endpoint.ts
   export default defineEventHandler(async (event) => {
     const database = globalThis.database;
     // Use the database connection here
   });
This approach ensures that the database connection is initialized only once when the server starts, and it's reused across all API calls. It's an efficient way to manage your database connection in a Nuxt server environment. For more advanced usage and configuration options, you can refer to the Nuxt Server Documentation. Remember to handle connection errors and implement proper connection pooling if needed, depending on your specific database and requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I mean this answer is actually pretty good and is something I considered but isn't really compatible with typescript as globalThis.database would have a type of any and would give out typescript errors in both files

Hi, the answer of the bot is just to tell you that the logic should be in a /server/plugins file. That will run at first and it will create your database connection. You have to write the logic yourself, for example if your db is in mongo, you can use mongoose to create a connection with your db in a server plugin
