Tauri: Desktop Apps on Windows, MacOS, Linux with JavaScript & Rust

Tauri is a tool for building cross-platform desktop apps on Windows, MacOS, and Linux with JavaScript & Rust. It is very lightweight and fast compared to similar tools like Electron. 

Introduction

Tauri is a framework for building tiny, blazingly fast binaries for all major desktop platforms. Developers can integrate any front-end framework that compiles to HTML, JS and CSS for building their user interface. The backend of the application is a rust-sourced binary with an API that the front-end can interact with.

The user interface in Tauri apps currently leverages tao as a window handling library on macOS and Windows, and gtk on Linux via the Tauri-team incubated and maintained WRY, which creates a unified interface to the system webview (and other goodies like Menu and Taskbar), leveraging WebKit on macOS, WebView2 on Windows and WebKitGTK on Linux.

Get Started

If you are interested in making a tauri app, please visit the documentation website. This README is directed towards those who are interested in contributing to the core library. But if you just want a quick overview about where tauri is at in its development, here's a quick burndown:

Development

Tauri is a system composed of a number of moving pieces:

Infrastructure

  • Git for code management
  • GitHub for project management
  • GitHub actions for CI and CD
  • Discord for discussions
  • Netlify-hosted documentation website
  • DigitalOcean Meilisearch instance

Major Runtimes

  • Node.js for running the CLI (deno and pure rust are on the roadmap)
  • Cargo for testing, running the dev service, building binaries and as the runtime harness for the webview

Major Languages

  • Rust for the CLI
  • ECMAScript bindings to the Rust API, written in typescript
  • Rust for bindings, rust side of the API, harnesses
  • Rust plugins to Tauri backend

Operating systems

Tauri core can be developed on Mac, Linux and Windows, but you are encouraged to use the latest possible operating systems and build tools for your OS.

Contributing

Before you start working on something, it's best to check if there is an existing issue first. It's also a good idea to stop by the Discord server and confirm with the team if it makes sense or if someone else is already working on it.

Please make sure to read the Contributing Guide before making a pull request.

Thank you to everyone contributing to Tauri!

Documentation

Documentation in a polyglot system is a tricky proposition. To this end, we prefer to use inline documentation of Rust code and at JSDoc in typescript / javascript code. We autocollect these and publish them using Docusaurus v2 and netlify. Here is the hosting repository for the documentation site: https://github.com/tauri-apps/tauri-docs

Testing & Linting

Test all the things! We have a number of test suites, but are always looking to improve our coverage:

  • Rust (cargo test) => sourced via inline #[cfg(test)] declarations
  • TS (jest) => via spec files
  • Smoke Tests (run on merges to latest)
  • eslint, clippy

CI/CD

We recommend you read this article to understand better how we run our pipelines: https://www.jacobbolda.com/setting-up-ci-and-cd-for-tauri/

Organization

Tauri aims to be a sustainable collective based on principles that guide sustainable free and open software communities. To this end it has become a Programme within the Commons Conservancy, and you can contribute financially via Open Collective.

📢 Announcement

ChatGPT Prompts!

This is a major and exciting update. It works like a Telegram bot command and helps you quickly populate custom models to make chatgpt work the way you want it to. This project has taken a lot of my spare time, so if it helps you, please help spread the word or star it would be a great encouragement to me. I hope I can keep updating it and adding more interesting features.

How does it work?

You can look at awesome-chatgpt-prompts to find interesting features to import into the app. You can also use Sync Prompts to sync all in one click, and if you don't want certain prompts to appear in your slash commands, you can disable them.

chatgpt menu chatgpt sync prompts

  • In the chatgpt text input area, type a character starting with / to bring up the command prompt, press the spacebar, and it will fill the input area with the text associated with the command by default (note: if it contains multiple command prompts, it will only select the first one as the fill, you can keep typing until the first prompted command is the one you want, then press the spacebar.
  • Or use the mouse to click on one of the multiple commands). When the fill is complete, you simply press the Enter key.
  • Under the slash command, use the tab key to modify the contents of the {q} tag (only single changes are supported #54). Use the keyboard (arrow up) and (arrow down) keys to select the slash command.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

micro-mobility

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

benefits-micromobility

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

  • Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
  • Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
  • Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
  • Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:

It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.

We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.

Developers can integrate any front-end framework that compiles to HTML, JS and CSS for building their user interface. The backend of the application is a rust-sourced binary with an API that the front-end can interact with.

The user interface in Tauri apps currently leverages tao as a window handling library on macOS and Windows, and gtk on Linux via the Tauri-team incubated and maintained WRY, which creates a unified interface to the system webview (and other goodies like Menu and Taskbar), leveraging WebKit on macOS, WebView2 on Windows and WebKitGTK on Linux.

Development

Tauri is a system composed of a number of moving pieces:

Infrastructure

  • Git for code management
  • GitHub for project management
  • GitHub actions for CI and CD
  • Discord for discussions
  • Netlify-hosted documentation website
  • DigitalOcean Meilisearch instance

Major Runtimes

  • Node.js for running the CLI (deno and pure rust are on the roadmap)
  • Cargo for testing, running the dev service, building binaries and as the runtime harness for the webview

Major Languages

  • Rust for the CLI
  • ECMAScript bindings to the Rust API, written in typescript
  • Rust for bindings, rust side of the API, harnesses
  • Rust plugins to Tauri backend

Operating systems

Tauri core can be developed on Mac, Linux and Windows, but you are encouraged to use the latest possible operating systems and build tools for your OS.

Contributing

Before you start working on something, it's best to check if there is an existing issue first. It's also a good idea to stop by the Discord server and confirm with the team if it makes sense or if someone else is already working on it.

Please make sure to read the Contributing Guide before making a pull request.

Thank you to everyone contributing to Tauri!

Documentation

Documentation in a polyglot system is a tricky proposition. To this end, we prefer to use inline documentation of Rust code and at JSDoc in typescript / javascript code. We autocollect these and publish them using Docusaurus v2 and netlify. Here is the hosting repository for the documentation site: https://github.com/tauri-apps/tauri-docs

Testing & Linting

Test all the things! We have a number of test suites, but are always looking to improve our coverage:

  • Rust (cargo test) => sourced via inline #[cfg(test)] declarations
  • TS (jest) => via spec files
  • Smoke Tests (run on merges to latest)
  • eslint, clippy

CI/CD

We recommend you read this article to understand better how we run our pipelines: https://www.jacobbolda.com/setting-up-ci-and-cd-for-tauri/

Organization

Tauri aims to be a sustainable collective based on principles that guide sustainable free and open software communities. To this end it has become a Programme within the Commons Conservancy, and you can contribute financially via Open Collective.

Semver

tauri is following Semantic Versioning 2.0.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.
