Vue Quickstart

Learn how to query data from Convex in a Vue app.

This quickstart guide uses a community-maintained Vue client for Convex.

1. Create a Vue site

   Create a Vue site using the npm create vue@latest my-vue-app command.

   Convex will work with any set of options but to follow this quickstart most closely choose:

   • Yes to "Add TypeScript?"
   • No to everything else

   
   

   npm create vue@latest my-vue-app
2. Install the Convex library

   To get started, install the convex package.

   cd my-vue-app && npm install @convex-vue/core @vueuse/core convex
3. Set up a Convex dev deployment

   Next, run npx convex dev. This will prompt you to log in with GitHub, create a project, and save your production and deployment URLs.

   It will also create a convex/ folder for you to write your backend API functions in. The dev command will then continue running to sync your functions with your dev deployment in the cloud.

   npx convex dev
4. Create sample data for your database

   In a new terminal window, create a sampleData.jsonl file with some sample data.

   sampleData.jsonl

   {"text": "Buy groceries", "isCompleted": true}
   {"text": "Go for a swim", "isCompleted": true}
   {"text": "Integrate Convex", "isCompleted": false}
5. Add the sample data to your database

   Now that your project is ready, add a tasks table with the sample data into your Convex database with the import command.

   npx convex import --table tasks sampleData.jsonl
6. Expose a database query

   Add a new file tasks.ts in the convex/ folder with a query function that loads the data.

   Exporting a query function from this file declares an API function named after the file and the export name, api.tasks.get.

   convex/tasks.ts

   import { query } from "./_generated/server";
   
   export const get = query({
     args: {},
     handler: async (ctx) => {
       return await ctx.db.query("tasks").collect();
     },
   });
7. Wire up the ConvexProvider

   In src/main.ts set up the Convex client there to make it available on every page of your app.

   src/main.ts

   import "./assets/main.css";
   
   import { createApp } from "vue";
   import App from "./App.vue";
   import { createConvexVue } from "@convex-vue/core";
   
   const app = createApp(App);
   
   const convexVue = createConvexVue({
     convexUrl: import.meta.env.VITE_CONVEX_URL,
   });
   
   app.use(convexVue).mount("#app");
8. Display the data in your app

   In src/App.vue use useQuery to subscribe your api.tasks.get API function.

   src/App.vue

   <script setup lang="ts">
   
   import { useConvexQuery } from "@convex-vue/core";
   import { api } from "../convex/_generated/api";
   
   const { data, isLoading } = useConvexQuery(api.tasks.get, {});
   </script>
   
   <template>
     <div class="wrapper">
       <ul v-if="!isLoading">
         <li v-for="todo in data">
           {{ todo.text }} {{ todo.isCompleted ? "☑" : "☐" }}
         </li>
       </ul>
       <span v-else> loading... </span>
     </div>
   </template>
9. Start the app

   Start the app, open http://localhost:5173 in a browser, and see the list of tasks.

   npm run dev
