海外TECH	DEV Community	How to Build a Telegram Bot using Typescript & Node.js	https://dev.to/eludadev/how-to-build-a-telegram-bot-using-typescript-nodejs-3j5e	How to Build a Telegram Bot using Typescript amp Node js IntroductionIn this tutorial you ll learn all the steps that go into building a dead simple Telegram bot and hosting it on the cloud It will greet people and apply FANCY text effects You ll be writing code using the Typescript language and running it on the Node js server environment And seeing as Telegram bots are built on an HTTP based API you ll be using the GrammY framework for higher level abstractions and a better programming experience PrerequisitesBefore writing any code make sure to have the following programs installed on your computer Telegram client Node js v NPM v and cURL VS Code or any other IDE of choice You ll be using Cyclic to host this project on the cloud so make sure to sign up referral link and take advantage of the Free Forever tier And while you don t have to be an expert in it you should know a bit of Typescript You ll be using it to write all the code in this tutorial Setup the Project Downloading the starter filesStart up this project by cloning the final version into your computer git clone cd telegram botAnd make sure to roll it back to its very first stage so you can learn how to build the rest of it in this tutorial git reset hard eaaeedabdcbcfddaAfter that s done install the project s dependencies npm install Getting your Telegram bot API tokenUsing the Telegram client start a conversation with the BotFather Send it the following messages newbotYour bot name Your bot username can t contain spaces and must end in “bot After that create a new file in the project s root directory called env Paste the following line into that file replacing lt YOUR API TOKEN gt with your bot s API token that you just got from the last message with BotFather TELEGRAM TOKEN lt YOUR API TOKEN gt Initializing the Telegram botCreate a new file called bot ts in the src directory That s where you ll be writing code for the rest of this tutorial You ll be using the GrammY framework to build this bot it s much easier this way instead of interacting directly with the API routes Head into the bot script and import the library in question import Bot from grammy Create a bot using the Telegram tokenconst bot new Bot process env TELEGRAM TOKEN As you can see the bot is created with the TELEGRAM TOKEN variable that you just set in the env file After that handle all message events by responding with a friendly robot introduction const introductionMessage Hello I m a Telegram bot I m powered by Cyclic the next generation serverless computing platform lt b gt Commands lt b gt yo Be greeted by me effect text Show a keyboard to apply text effects to text const replyWithIntro ctx any gt ctx reply introductionMessage parse mode HTML bot on message replyWithIntro Take note of the parse mode parameter It s used to allow HTML tags in the message response such as lt b gt Commands lt b gt And finally start up the bot by running one method bot start Follow that by executing the bot script npm run devAnd boom You ve got yourself a dead simple bot running on your computer You can test it out by sending it a message on Telegram you may want to follow the link previously given to you by BotFather Handle Basic CommandsTelegram bots can handle commands which aren t much different from ordinary messages The syntax for such interactions follows the following format bot command start replyWithIntro Test it out by sending the start message to your bot Note that your program is automatically updated once you modify the bot script After that s done modify your bot to handle the yo command It will simply respond with the username of the sender Handle the yo command to greet the userbot command yo ctx gt ctx reply Yo ctx from username And since the bot on “message event handler is on top it will catch all messages and the start and yo commands won t have an effect Please make sure to always keep it at the bottom of the file Keep this at the bottom of the filebot on message replyWithIntro Build Inline KeyboardsTelegram bots can also respond with a set of buttons underneath the message Let s do a simple demonstration Change the introductory response to also contain a button that links users to the Cyclic website the platform that we ll use to deploy our bot to the cloud for free at the end of this tutorial import InlineKeyboard from grammy const aboutUrlKeyboard new InlineKeyboard url Host your own bot for free const replyWithIntro ctx any gt ctx reply introductionMessage reply markup aboutUrlKeyboard parse mode HTML After this step you may want to re execute the bot script after interrupting it with the Ctrl C keyboard combination npm run dev A more advanced exampleLet s now do a more advanced example Other inline keyboards may contain general buttons

month in seconds Polish the Telegram BotIt s often useful for Telegram bots to display a list of supported commands and while we re already doing that in the introductory message there s a more formal way of doing so and it s as simple as one command Suggest commands in the menubot api setMyCommands command yo description Be greeted by the bot command effect description Apply text effects on the text usage effect text Note that to see the new menu you must restart your Telegram client Furthermore professional bots come with a profile picture and a well formed description You can do all of that by contacting BotFather Edit botEdit about Edit description Edit botpic Deploy the Telegram Bot to the Cloud Long Polling vs WebhooksThere are two fundamentally different ways of deploying your Telegram bot to the web The first one is Long Polling and we ve already been using it in this tutorial by running bot start With it bots constantly send requests to the Telegram servers checking for new messages and responding to them accordingly This approach is not compatible with the serverless architecture as the latter expects applications to only run once and only on demand “Serverless means applications are only on for the time it takes to process individual requests They are suspended immediately after each response is sent ーCyclic docs The solution to this problem is deployment by Webhooks an alternative strategy that makes the Telegram client itself contact your bot when there s a new message And while this comes with its own drawbacks it s fully compatible with serverless architecture Using Webhooks for deploymentBy following the NODE ENV environment variable we can tell whether the bot instance is running in a development or a production stage Replace the bot start command with the following import webhookCallback from grammy import express from express Start the serverif process env NODE ENV production Use Webhooks for the production server const app express app use express json app use webhookCallback bot express const PORT process env PORT app listen PORT gt console log Bot listening on port PORT else Use Long Polling for development bot start Pushing all files to a Github RepositoryIt s imperative that we use a Github repository to store our bot files so we can deploy it to the cloud After creating a new repository either public or private run the following commands to link it with your local Git instance replacing lt YOUR GH REPO LINK gt with your repo s URL export GH REPO lt YOUR GH REPO LINK gt git remote remove origingit remote add origin GH REPO git After that stage commit and push your files to the new remote origin git add git commit m Build the Telegram bot git branch M maingit push origin main Deploying for free using CyclicAfter creating your Cyclic account referral link use it to deploy your new Telegram bot It s free forever and no credit card is required Note that you must sign up using the same Github account that you used to create your bot s repository Open your Cyclic dashboard click on the Deploy button and switch to the “Link your own tab Search for your bot s repo and click on the “Connect button Then sit back and watch it do all the work for you The final step is setting the same environment variables as you did in the env file Open your Cyclic deployment s dashboard page switch to the Variables page and set the appropriate values for the environment variables NODE ENV productionTELEGRAM TOKEN your bot s API token same as env file Connecting your Telegram bot to your Cyclic serverYou want to tell Telegram to send the Webhook requests to your Cyclic server So conclude this project by copying your Cyclic deployment s URL and running these commands export TELEGRAM API TOKEN YOUR TELEGRAM API TOKENexport TELEGRAM WEBHOOK URL YOUR CYCLIC DEPLOYMENT URLcurl TELEGRAM API TOKEN setWebhook url TELEGRAM WEBHOOK URL And boom Your bot s now actively running on the cloud You may stop your local development instance by pressing Ctrl C and notice how your bot is still working ConclusionYou ve successfully reached the end of this tutorial There are many more things you could add to this bot including but not limited to games error handling and internationalization You may also want to learn more about Telegram bots And here are some resources to advance your knowledge about serverless
