# Telegram Mini Apps Next.js Template



This template demonstrates how developers can implement a web application on the

Telegram Mini Apps platform using the following technologies and libraries:



- [Next.js](https://nextjs.org/)

- [TypeScript](https://www.typescriptlang.org/)

- [TON Connect](https://docs.ton.org/develop/dapps/ton-connect/overview)

- [@telegram-apps SDK](https://docs.telegram-mini-apps.com/packages/telegram-apps-sdk/2-x)

- [Telegram UI](https://github.com/Telegram-Mini-Apps/TelegramUI)



> The template was created using [pnpm](https://pnpm.io/). 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:



```Bash

pnpm install

```



## Scripts



This project contains the following scripts:



- `dev`. Runs the application in development mode.

- `dev:https`. Runs the application in development mode using self-signed SSL

  certificate.

- `build`. Builds the application for production.

- `start`. Starts the Next.js server in production mode.

- `lint`. Runs [eslint](https://eslint.org/) to ensure the code quality meets

  the required

  standards.



To run a script, use the `pnpm run` command:



```Bash

pnpm run {script}

# Example: pnpm run build

```



## Create Bot and Mini App



Before you start, make sure you have already created a Telegram Bot. Here is

a [comprehensive guide](https://docs.telegram-mini-apps.com/platform/creating-new-app)

on how to do it.



## Run



Although Mini Apps are designed to be opened

within [Telegram applications](https://docs.telegram-mini-apps.com/platform/about#supported-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:



```bash

pnpm run dev

```



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



```bash

▲ Next.js 14.2.3

- Local:        http://localhost:3000



✓ Starting...

✓ Ready in 2.9s

```



To view the application, you need to open the `Local`

link (`http://localhost:3000` 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/hooks/useTelegramMock.ts` file, which is imported in the application's

`Root` component, 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.



### Run Inside Telegram



Although it is possible to run the application outside of Telegram, it is

recommended to develop it within Telegram for the most accurate representation

of its real-world functionality.



To run the application inside Telegram, [@BotFather](https://t.me/botfather)

requires an HTTPS link.



This template already provides a solution.



To retrieve a link with the HTTPS protocol, consider using the `dev:https`

script:



```bash

$ pnpm run dev:https



▲ Next.js 14.2.3

- Local:        https://localhost:3000



✓ Starting...

✓ Ready in 2.4s

```



Visiting the `Local` link (`https://localhost:3000` in this example) in your

browser, you will see the following warning:



![SSL Warning](assets/ssl-warning.png)



This browser warning is normal and can be safely ignored as long as the site is

secure. Click the `Proceed to localhost (unsafe)` button to continue and view

the application.



Once the application is displayed correctly, submit the

link `https://127.0.0.1:3000` (`https://localhost:3000` is considered as invalid

by BotFather) as the Mini App link to [@BotFather](https://t.me/botfather).

Then, navigate to [https://web.telegram.org/k/](https://web.telegram.org/k/),

find your bot, and launch the Telegram Mini App. This approach provides the full

development experience.



## Deploy



The easiest way to deploy your Next.js app is to use

the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme)

from the creators of Next.js.



Check out

the [Next.js deployment documentation](https://nextjs.org/docs/deployment) for

more details.
