Storing Data in Tauri JS: Effortless Data Management

GX Anshu | Mon Aug 14 2023

Are you looking to use the power of Tauri JS to effortlessly store and manage your data? Look no further! In this guide, we’ll walk you through the process of using Tauri’s File and Path APIs to store data in JSON files within the appData directory. Whether you’re a intermidate developer or just starting your journey, this tutorial will have you storing data like a pro in no time! 🚀

Understanding Tauri’s File and Path APIs

Before we dive into the development process, let’s get familiar with Tauri’s File and Path APIs. These APIs are your helpers when it comes to handling file-related tasks. The File API lets you interact with files, while the Path API helps you manage file paths with ease.

Accessing Directories

Tauri provides access to various directories where you can store your application’s data. These include:

  • appData: Stores user-specific data that persists across sessions.
  • userData: For user-specific data that should be backed up and synchronized.
  • cache: Ideal for temporary and non-critical data.
  • config: Houses configuration files.

Storing Data in JSON Files

Let’s get hands-on! Here’s how you can use Tauri’s APIs to store data in a JSON file within the appData directory.

import { Tauri } from "tauri/api";

interface UserData {
  name: string;
  age: number;
  email: string;

// Store data into a JSON file
async function storeData(data: UserData): Promise<void> {
  try {
    const jsonData = JSON.stringify(data);
    const filePath = Tauri.path.join(Tauri.path.appData, "userdata.json");
    await Tauri.fs.writeTextFile({ path: filePath, contents: jsonData });
    console.log("Data saved successfully!");
  } catch (error) {
    console.error("Error saving data:", error);

In the above example, we first convert our data object into a JSON string. Then, we define the file path using Tauri’s Path API by joining the appData directory and a filename. Finally, we use the File API’s writeTextFile method to save our data to the JSON file.

Retrieving stored data is just as simple:

// Retrieve and parse stored data
async function retrieveData(): Promise<UserData | null> {
  try {
    const filePath = Tauri.path.join(Tauri.path.appData, "userdata.json");
    const jsonData = await Tauri.fs.readTextFile({ path: filePath });
    return JSON.parse(jsonData) as UserData;
  } catch (error) {
    console.error("Error reading data:", error);
    return null;

Congratulations! You’ve now mastered the art of storing and managing data in Tauri JS. With the File and Path APIs at your fingertips, you can seamlessly handle data storage tasks. Whether you’re creating a user profile system or saving app settings, Tauri’s got your back.

Remember, Tauri’s straightforward APIs and your newfound knowledge make data storage a breeze. So go ahead, dive into the world of Tauri JS, and unleash the potential of your applications!

Now, go forth and create with confidence! 🎉📦
