This is the main server code of হুতুম ১০১ (HUTUM 101), a facebook chatbot. The main purpose of this chatbot is to share the academic materials among the student's of Khulna University of Engineering and Technology (KUET). To do that job I have used dialogflow. It's a Lifelike conversational AI with state-of-the-art virtual agents. It is mainly used to recognize the user command. But these virtual agents can't call any API (Application Programming Interface). When I was trying to implement a searching system which can search a database of books and give the chatbot user if the book is in our google drive/telegram channle or not, I could not do with dialogflow. To do that I have written this server code with the help of Node.js and express. Then connected this server with dialogflow.
In this project various npm packages are used. These are:
- moment (For Date and time)
- actions-on-google
- axios
- cheerio
- dialogflow-fulfillment
- dotenv
- ejs
- express
- googleapis
- iso-639-1
- mongoose
- nodemailer
- nodemailer-express-handlebars
- semver
হুতুম ১০১ (HUTUM 101) chatbot has a multiple usage. As mentioned above it can share study materials with the students of KUET. Besides there are telegram channels for movies, books of this chatbot. There are a group of people who maintain these channels and spreadsheets for indexing what they are uploading. This server take the indexed data from these spreadsheets using sheetdb.io and store the data in MongoDB. A user can easily search through all the movies or books from the chatbot just typing specific commands. Example:
movie search for searching movies
book search for searching books
A user can also make request for books and movies if he/she is a student of KUET/CUET/RUET. Through the institutional email address they can send request to the admin and the user is notified through automated email from the server if his/her requested is received by the admin. To request a movie or book user just need to type some specific words. These are:
movie request for requesting movies
book request for requesting movies
Besides searching movies/books and giving academinc materials, there are other information that the chatbot can provide like:
- Daily Namaz Time
- Real Time Weather Report
- KUET bus data
and many more.
The installation process of this server is very easy but get a result from this server will be a little hectic. Because this server is not the only part of this chatbot. This main language processing part is done through dialogflow. dialogflow mainly process the user input if it matches with specific command then it will ask for data from the server. Otherwise anyone can run the server in his/her local machine if he/she has already installed Node.js and npm. By running the folloiwng command.
npm i
And adding proper environment variables in the .env file.
