tRPC Procedure at Vue js Nation 2023: Mighty Bites with Cody Bontecou

tRPC Procedure is a powerful tool developed by Cody Bontecou that allows developers to easily create and manage remote procedure calls in their Vue.js applications. In this tutorial, we will walk you through the steps of setting up and using tRPC Procedure in a Vue.js application, specifically focusing on the Mighty Bites project for Vue.js Nation 2023.

Step 1: Install tRPC Procedure

The first step in using tRPC Procedure is to install it in your Vue.js project. You can do this by running the following command in your terminal:

npm install @trpc/procedure

Step 2: Set up the tRPC Procedure Server

Next, you will need to set up the tRPC Procedure server in your Vue.js application. This involves creating a new file called trpc-server.js in the root directory of your project. In this file, you will define the procedures that you want to expose to your client application.

Here is an example of how you can set up a simple procedure in tRPC Procedure:

import { createProcedure } from '@trpc/procedure';

const getUserProcedure = createProcedure({
  input: {
    id: 'number',
  },
  resolve: async ({ id }) => {
    const user = await fetch(`https://api.example.com/users/${id}`).then((res) => res.json());
    return user;
  },
});

In this example, we are creating a procedure called getUserProcedure that takes an id as input and fetches a user from an API. You can define as many procedures as you need in this file.

Step 3: Expose tRPC Procedure to the Client

Once you have defined your procedures in the trpc-server.js file, you will need to expose them to the client application. To do this, you can use the createClient function provided by tRPC Procedure.

Here is an example of how you can set up a tRPC Procedure client in your Vue.js application:

import { createClient } from '@trpc/procedure';

const client = createClient({
  endpoint: '/trpc',
});

export const getUser = client.procedure(getUserProcedure);

In this example, we are creating a client that connects to the tRPC Procedure server at the /trpc endpoint. We are then exposing the getUserProcedure that we defined earlier to the client application.

Step 4: Use tRPC Procedure in Vue.js Components

Now that you have set up tRPC Procedure in your Vue.js application, you can start using it in your components. Here is an example of how you can call the getUser procedure in a Vue.js component:

<template>
  <div>
    <button @click="fetchUser">Fetch User</button>
    <div v-if="user">{{ user.name }}</div>
  </div>
</template>

<script>
import { getUser } from '@/trpc-server';

export default {
  data() {
    return {
      user: null,
    };
  },
  methods: {
    async fetchUser() {
      this.user = await getUser({ id: 1 });
    },
  },
};
</script>

In this example, we are creating a button that calls the fetchUser method when clicked. This method calls the getUser procedure with the id parameter set to 1 and stores the result in the user data property. The user’s name is then displayed in the component using Vue.js templating.

And that’s it! You have successfully set up and used tRPC Procedure in your Vue.js application, specifically focusing on the Mighty Bites project for Vue.js Nation 2023. tRPC Procedure is a powerful tool that can streamline remote procedure calls in your Vue.js application, making it easier to manage and maintain complex API interactions. Experiment with different procedures and see how tRPC Procedure can enhance the functionality of your applications.
