NodeJS Noob

• Understanding and Learning about Node JS.

---

Task 1 ( Notes App )

• This is a basic app using only Node JS. It is about how can I interact with File System by Javascript Language.

---

Task 2 ( Weather App )

• This is the first App using Express and Node JS. By this task I learned how can fetch data from APIs and display then in client Side using NodeJS. Here I use Weather Stack api for fetching current Weather Status of a particular Place.

---

Task 3 ( Image Uploader using Multer )

• This is very important. By completing this task We can learn how can upload a image in Server Side and saved them in local File System.

---

Task 4 ( Chat App using Socket.io )

• Nowadays this is very trending technology. Here I learn how use websockets and how to connect Server Side and Client Side together.

---

Task 5 ( Vidjot using Passport Authentication )

• This is a fully functional app using Express as a Server. Here I learn how to use Passport for authentication, how to override the request using method-override, about flash messages using Connect-flash and the main thing how to interact with Database (MongoDB) in Backend.

---

Task 6 ( CSV import using Multer and csvtojson module & CSV export using json2csv module )

• This is a basic implementation by which we can upload a bunch of data into Database by uploading a CSV file.

---

Task 7 ( File Uploads on MongoDB GridFS )

• This is a Simple Express App that uploads Files on MongoDB, here we don't store any files on our local File System. It can be used in Production Level Applications.

• Here I use Multer for uploading files as usual. Also I used multer-gridfs-storage to store files directly on MongoDB GridFS Bucket and gridfs-stream for dealing CRUD operations with files on MongoDB GridFS.

---

Task 7 ( Pagination in NodeJS )

• Pagination is very important topic for Backend Web Development. We don't want to send all data to the client in a single request. If Data become quite large, it may cause problems with the server and may result in Server Errors due to overloaded Data. Here I implement a Simple Pagination query using Node JS and MongoDB.

---

Task 8 ( Understanding NodeJS CLI )

• This is a simple example how to use CLI to interact with the Database. Here I use Commander and Inquirer Module for building Commands and asking Questions, MongoDB used as Database to store the information of Customer.
