Node.js Notes

Node js handle request asynchronously using single thread.

Waiter(Thread) :

Table1 (Request 1)                           Table 2 (Request 2)

Thread read request 1 and wait for response at the same time goes to table 2 and process there request and if event queue alert with request is processed of table 1 then it response to table 1 and so on.

Node should be used for real time application where we need data intensivity. not for cpu intensive application

Installation :

npm i

npm i express --save

npm i -g nodemon (For auto rerun)

npm i --save-dev nodemon (For dev dependency save for development purpose)
