frederikbache/vue-vroom: Type safe stores and mock API with minimal config

Vroom is a store and api mock generator for Vue.js and pinia, that lets you build applications fast and even before backend is ready.

See the full documentation here.

To get started setup of a Vue 3 project with Pinia, e.g. using create-vue. In this guide we will

1. Install Vroom package
2. Setup config
3. Setup global component types (for TS projects)
4. Install Vroom in our app
5. Fetch some data and show it
6. Use store actions to manipulate data

Vroom is built to work with Pinia and Vue 3. Vroom is targeted at modern browsers and uses the Fetch API instead of XMLHttpRequest.

Peer dependencies:

• Vue ^3.0.0
• Pinia ^2.0.0

Note: Vroom is still in alpha, so breaking changes might be introduced between each minor release.

To install Vroom

Create a vroom/index.ts file to store your configuration. This is a basic example that:

• Adds two models, book and author and sets up a relation between them (Read more about models)
• Enables the mock server and db (Read more about server)
• Seeds some test data into the mock db (Read more about seeding)
• Exports the autogenerated types for later use

// src/vroom/index.ts
import { createVroom, defineModel } from "vue-vroom";

const vroom = createVroom({
  models: {
    book: defineModel({
      schema: {
        title: { type: String },
        isFavourite: { type: Boolean },
      },
      belongsTo: {
        author: () => "author",
      },
    }),
    author: defineModel({
      schema: {
        name: { type: String },
      },
      hasMany: {
        books: () => "book",
      },
    }),
  },
  server: {
    enable: true,
  },
});

vroom.db.author.createMany(
  {
    name: "George R.R. Martin",
    books: vroom.db.book.createMany(
      { title: "A Game of Thrones" },
      { title: "A Clash of Kings" },
    ),
  },
  {
    name: "JRR Tolkien",
    books: vroom.db.book.createMany(
      { title: "The Hobbit" },
      { title: "The Lord of the rings" },
    ),
  },
);

export type Models = typeof vroom.types;

export default vroom;

It is recommended to split up models, config and seeds for better organisation and bundle optimization. See notes on organisation here

Vroom adds some global components. To get proper type hints on these add a components.d.ts file to your /src folder.

// src/components.d.ts
import type {
  FetchListComponent,
  FetchSingleComponent,
  FetchSingletonComponent,
} from "vue-vroom";
import type vroom from "@/vroom";

declare module "@vue/runtime-core" {
  export interface GlobalComponents {
    FetchList: FetchListComponent<typeof vroom>;
    FetchSingle: FetchSingleComponent<typeof vroom>;
    FetchSingleton: FetchSingletonComponent<typeof vroom>;
  }
}

Then import your vroom instance in main.ts file along with your pinia installation and install it

import { createApp } from "vue";
import { createPinia } from "pinia";
import vroom from "./vroom";
import App from "./App.vue";

const pinia = createPinia();
const app = createApp(App);

app.use(pinia);
app.use(vroom);
app.mount("#app");

Find a place you want to show some data e.g. App.vue and add the following

<template>
    <FetchList 
        model="book" 
        :sort="[{ field: 'title', dir: 'ASC' }]"
        :include="['author']"
    >
        <template #loading>Loading books...</template>

        <template #default="{bookItems}">
            <p v-for="book in bookItems" :key="book.id">
                {{ book.title }} was written by {{ book.author.name }}
            </p>
        </template>
    </FetchList>
</template>

<script lang="ts" setup></script>

• The FetchList component will in this example trigger a call to /books?sort=title,include=author
• It will pass the results into the default slot, when it's done loading
• It will keeps its results cached until it's unmounted (see more about cache)

There are three different components for fetching data

• FetchList
• FetchSingle
• FetchSingleton

Let's update the example above to be able to favourite a book

<template>
    <FetchList 
        model="book" 
        :sort="[{ field: 'title', dir: 'ASC' }]"
        :include="['author']"
    >
        <template #loading>Loading books...</template>

        <template #default="{bookItems}">
            <p v-for="book in bookItems" :key="book.id">
                {{ book.title }} was written by {{ book.author.name }}

                <button @click="toggleFavorite(book)">
                    {{ book.isFavourite ? 'Unfavourite' : 'Favourite' }}
                </button>
            </p>
        </template>
    </FetchList>
</template>

<script lang="ts" setup>
import vroom, { type Models } from '@/vroom';

const bookStore = vroom.stores.book();

function toggleFavourite(book: Models['book']) {
    bookStore.update(book.id, {
        isFavourite: !book.isFavourite
    })
}
</script>

This example uses the autogenerated store (all accessible on vroom.stores). Calling update will trigger a called to PATCH /books/:id along with data passed as the second argument
