Russian-English vocabulary exercise bot integrated with Telegram (https://core.telegram.org/bots/api). Words can be uploaded from excel files downloaded from https://translate.google.com/.

Structure

• infra package contains cloudformation scripts to bootstrap AWS infrastructure
• bot_server package contains source code of the bot

How to build

• Source package should contain config/configData.js file with configurations

// AWS Api Gateway url that triggers Lambda bot
exports.service_url = "...";
// SQS queue ARN, contains list of words to suggest
exports.sqs_url = "...";
// Token that is used to query telegram servers https://core.telegram.org/bots/api
exports.token = "...";
// Admin user chat id
exports.user_id = "...";
// AWS DDB table name and region
exports.aws = {
    tableName: "...",
    region: "..."
};

• Build of the bundles is done by webpack
package.json "scripts" contains commands to create .zip deployment packages of lambdas which are placed in dist folder

npm run build  // builds main telegram bot lambda zip
npm run build-update-queue // builds reload SQS queue lambda zip

• setWebhook.js is used to set Telegram web hook
