Telegram Mini Apps Vue Template

This template demonstrates how developers can implement a single-page application on the Telegram Mini Apps platform using the following technologies and libraries:

• Vue
• TypeScript
• TON Connect
• @telegram-apps SDK
• Vite

The template was created using npm. Therefore, it is required to use it for this project as well. Using other package managers, you will receive a corresponding error.

Install Dependencies

If you have just cloned this template, you should install the project dependencies using the command:

npm install

Scripts

This project contains the following scripts:

• dev. Runs the application in development mode.
• build. Builds the application for production.
• lint. Runs eslint to ensure the code quality meets the required standards.
• lint:fix. Runs eslint and fixes auto-fixable issues.
• type-check. Runs vue-tsc to check types.
• deploy. Deploys the application to GitHub Pages.

To run a script, use the npm run command:

npm run {script}
# Example: npm run build

Create Bot and Mini App

Before you start, make sure you have already created a Telegram Bot. Here is a comprehensive guide on how to do it.

Run

Although Mini Apps are designed to be opened within Telegram applications, you can still develop and test them outside of Telegram during the development process.

To run the application in the development mode, use the dev script:

npm run dev

After this, you will see a similar message in your terminal:

VITE v5.2.12  ready in 237 ms

➜  Local:   https://localhost:5173/vuejs-template
➜  Network: https://192.168.0.109:5173/vuejs-template

➜  press h + enter to show help

Here, you can see the Local link, available locally, and Network links accessible to all devices in the same network with the current device.

To view the application, you need to open the Local link (https://localhost:5173/reactjs-template in this example) in your browser:

It is important to note that some libraries in this template, such as @telegram-apps/sdk, are not intended for use outside of Telegram.

Nevertheless, they appear to function properly. This is because the src/mockEnv.ts file, which is imported in the application's entry point ( src/index.ts), employs the mockTelegramEnv function to simulate the Telegram environment. This trick convinces the application that it is running in a Telegram-based environment. Therefore, be cautious not to use this function in production mode unless you fully understand its implications.

Warning

Because we are using self-signed SSL certificates, the Android and iOS Telegram applications will not be able to display the application. These operating systems enforce stricter security measures, preventing the Mini App from loading. To address this issue, refer to this guide.

Deploy

This boilerplate uses GitHub Pages as the way to host the application externally. GitHub Pages provides a CDN which will let your users receive the application rapidly. Alternatively, you could use such services as Heroku or Vercel.

Manual Deployment

This boilerplate uses the gh-pages tool, which allows deploying your application right from your PC.

Configuring

Before running the deployment process, ensure that you have done the following:

1. Replaced the homepage value in package.json. The GitHub Pages deploy tool uses this value to determine the related GitHub project.
2. Replaced the base value in vite.config.ts and have set it to the name of your GitHub repository. Vite will use this value when creating paths to static assets.

For instance, if your GitHub username is telegram-mini-apps and the repository name is is-awesome, the value in the homepage field should be the following:

{
  "homepage": "https://telegram-mini-apps.github.io/is-awesome"
}

And vite.config.ts should have this content:

export default defineConfig({
  base: '/is-awesome/',
  // ...
});

You can find more information on configuring the deployment in the gh-pages docs.

Before Deploying

Before deploying the application, make sure that you've built it and going to deploy the fresh static files:

npm run build

Then, run the deployment process, using the deploy script:

npm run deploy

After the deployment completed successfully, visit the page with data according to your username and repository name. Here is the page link example using the data mentioned above: https://telegram-mini-apps.github.io/is-awesome

GitHub Workflow

To simplify the deployment process, this template includes a pre-configured GitHub workflow that automatically deploys the project when changes are pushed to the master branch.

To enable this workflow, create a new environment (or edit the existing one) in the GitHub repository settings and name it github-pages. Then, add the master branch to the list of deployment branches.

You can find the environment settings using this URL: https://github.com/{username}/{repository}/settings/environments.

In case, you don't want to do it automatically, or you don't use GitHub as the project codebase, remove the .github directory.

GitHub Web Interface

Alternatively, developers can configure automatic deployment using the GitHub web interface. To do this, follow the link: https://github.com/{username}/{repository}/settings/pages.

TON Connect

This boilerplate utilizes the TON Connect project to demonstrate how developers can integrate functionality related to TON cryptocurrency.

The TON Connect manifest used in this boilerplate is stored in the public folder, where all publicly accessible static files are located. Remember to configure this file according to your project's information.
