Building a Notebook Chrome Extension with Directus

Published July 11th, 2024

This article will guide you through building a Chrome extension using Vite and Directus. The extension will leverage Directus as the backend to store and manage data.

When a user clicks the extension while browsing a webpage, it will automatically capture the URL of the current webpage and prompt the user to add a note. Users will be able to view, edit, and delete their notes directly from the extension. This tutorial will not cover styling the extension, but light styling has been applied to the screenshots shown.

Before you start, you will need a Directus project. Follow the Quickstart guide to create one if needed.

Set Up Your Directus Project

Create Notes Collection

Create a new collection called notes with all optional fields enabled. Create the following additional fields:

  • website - new field with type string
  • note - new field with type string

Notes Collection showing all optional fields and the website and note custom fields

Set Up Roles

In order to create new note, edit note or delete note on behalf of user, we need to create separate role. Create a customer role for new users. In the access control settings for the role, allow creation on the notes collection and custom read, edit, and delete permissions: user_created equals $CURRENT_USER.

Customer Role Permissions

Filter Notes

Initialize Extension

Open your terminal and run the following commands to create a new project, install dependencies, and run the project:

bash
npm create vite@latest directus-webnote-keeper -- --template vue
cd directus-webnote-keeper
npm install
npm install @directus/sdk js-cookie vue-router
npm run dev
npm create vite@latest directus-webnote-keeper -- --template vue
cd directus-webnote-keeper
npm install
npm install @directus/sdk js-cookie vue-router
npm run dev

Add a manifest.json file in root directory of the project:

json
{
    "name": "Directus WebNote Keeper",
    "version": "1.0",
    "manifest_version": 3,
    "author": "Jay Bharadia",
    "description": "Directus WebNote Keeper for capturing urls and store in directus.",
    "icons": {
        "16": "icon.png",
        "32": "icon.png",
        "48": "icon.png",
        "128": "icon.png"
    },
    "action": {
        "default_title": "Directus WebNote Keeper",
        "default_popup": "index.html"
    },
    "permissions": ["activeTab", "storage"]
}
{
    "name": "Directus WebNote Keeper",
    "version": "1.0",
    "manifest_version": 3,
    "author": "Jay Bharadia",
    "description": "Directus WebNote Keeper for capturing urls and store in directus.",
    "icons": {
        "16": "icon.png",
        "32": "icon.png",
        "48": "icon.png",
        "128": "icon.png"
    },
    "action": {
        "default_title": "Directus WebNote Keeper",
        "default_popup": "index.html"
    },
    "permissions": ["activeTab", "storage"]
}

You must tell browser about the functionality and permissions required by this extension. You can read more about declaring permissions in the Google Extensions Docs.

  • activeTab: We need to read the website from current active tab.
  • storage: Store the authentication token as a cookie.

Create Directus SDK Plugin

Create new file plugins/directus.js

js
import { createDirectus, rest, authentication } from "@directus/sdk";

import Cookies from "js-cookie";
const directus = createDirectus("your-project-url")
    .with(
        authentication("cookie", {
            autoRefresh: true,
            credentials: "include",
            storage: {
                get() {
                    if (Cookies.get("directus_auth"))
                        return JSON.parse(Cookies.get("directus_auth"));
                    else return null;
                },
                set(data) {
                    Cookies.set("directus_auth", JSON.stringify(data));
                },
            },
        })
    )
    .with(rest());

export default directus;
import { createDirectus, rest, authentication } from "@directus/sdk";

import Cookies from "js-cookie";
const directus = createDirectus("your-project-url")
    .with(
        authentication("cookie", {
            autoRefresh: true,
            credentials: "include",
            storage: {
                get() {
                    if (Cookies.get("directus_auth"))
                        return JSON.parse(Cookies.get("directus_auth"));
                    else return null;
                },
                set(data) {
                    Cookies.set("directus_auth", JSON.stringify(data));
                },
            },
        })
    )
    .with(rest());

export default directus;

Replace your-project-url with your Directus Project's URL. Then, open main.js and import the plugin:

js
import directus from "./plugins/directus.js";
app.provide("directus", directus);
import directus from "./plugins/directus.js";
app.provide("directus", directus);

Setup Routing

Create new plugins/router.js file:

js
import { createWebHistory, createRouter } from "vue-router";
import HomeView from "../views/home.vue";

const routes = [
    { path: "/", name: "home", meta: { public: false }, component: HomeView },
];

const router = createRouter({
    history: createWebHistory(),
    routes,
});

export default router;
import { createWebHistory, createRouter } from "vue-router";
import HomeView from "../views/home.vue";

const routes = [
    { path: "/", name: "home", meta: { public: false }, component: HomeView },
];

const router = createRouter({
    history: createWebHistory(),
    routes,
});

export default router;

Include the router instance in main.js:

js
import directus from "./plugins/directus.js";
import router from "./plugins/router.js"; 

app.provide("directus", directus);
app.use(router); 
import directus from "./plugins/directus.js";
import router from "./plugins/router.js"; 

app.provide("directus", directus);
app.use(router); 

Load Extension

Before moving further, build the extension and make sure it runs in your browser. Add build command in package.json:

json
"build-extension": "vite build && cp manifest.json dist/"
"build-extension": "vite build && cp manifest.json dist/"

And then run the build command from your terminal:

npm run build-extension
npm run build-extension

Open Google Chrome, go to chrome://extensions, click on 'Load Unpacked button' button, and select your project's dist folder.

Setup Signup

Create new src/views/signup.vue file:

html
<template>
    <div>
        <form @submit.prevent="signup">
            <label>Name</label>
            <input type="text" v-model="name" required />

            <label>Email</label>
            <input type="email" v-model="email" required />

            <input type="password" v-model="password" required />
            <button type="submit">Signup</button>
            <p>
                Already have account?
                <span @click="$router.push({ name: 'login' })">Login</span>

        data() {
            return {
                name: "",
                email: "",
                password: "",
            };
        },
        methods: {
            async signup() {
                await this.directus.request(
                    registerUser({
                        first_name: this.name,
                        email: this.email,
                        password: this.password,
                    })
                );
                this.$router.push({ name: "login" });
            },
        },
    };
</script>
<template>
    <div>
        <form @submit.prevent="signup">
            <label>Name</label>
            <input type="text" v-model="name" required />

            <label>Email</label>
            <input type="email" v-model="email" required />

            <label>Password</label>
            <input type="password" v-model="password" required />
            <button type="submit">Signup</button>
            <p>
                Already have account?
                <span @click="$router.push({ name: 'login' })">Login</span>
            </p>
        </form>
    </div>
</template>

<script>
    import { registerUser } from "@directus/sdk";
    export default {
        inject: ["directus"],
        data() {
            return {
                name: "",
                email: "",
                password: "",
            };
        },
        methods: {
            async signup() {
                await this.directus.request(
                    registerUser({
                        first_name: this.name,
                        email: this.email,
                        password: this.password,
                    })

                this.$router.push({ name: "login" });
            },
        },
    };
</script>

Create and Edit Notes

For creating and editing note, we will create only one file named upsert.vue. Based on route parameter, create or edit note logic is used. For creating a new note, route will be /note/+, and when editing, the route will be /note/id (id will be a unique number). Create upsert.vue:

html
<template>
    <div>
        <textarea
            rows="10"
            v-model="note"
            placeholder="Notes are great way to store helpful information to access later. Get Started..."
        ></textarea>
        <button @click="save">👍 Done</button>
    </div>
</template>

<script>

Load upsert.vue in router.js

js
import Upsert from "../views/upsert.vue";
import Upsert from "../views/upsert.vue";
js
{
        path: "/note/:id",
        name: "upsert",
        meta: { public: false },
        component: Upsert,
    },
{
        path: "/note/:id",
        name: "upsert",
        meta: { public: false },
        component: Upsert,
    },
