3>>> Databse view
##Installation
1.Initialize node Project
```shell
npm init -y
```
2.Express
```shell
npm i express
```
3.Install Mongoose
```shell
npm i mongoose
```
4.Install Cors(for sending response to client)
```shell
npm i cors
//expamle
var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.get('/products/:id', function (req, res, next) {
res.json({msg: 'This is CORS-enabled for all origins!'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
5.Install bcryptjs(for use hashed password)
```shell
npm i bcryptjs
ex==//
To hash a password:
var bcrypt = require('bcryptjs');
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash("B4c0/\/", salt, function(err, hash) {
// Store hash in your password DB.
});
});
To check a password:
// Load hash from your password DB.
bcrypt.compare("B4c0/\/", hash, function(err, res) {
// res === true
});
bcrypt.compare("not_bacon", hash, function(err, res) {
// res === false
});
// As of bcryptjs 2.4.0, compare returns a promise if callback is omitted:
bcrypt.compare("B4c0/\/", hash).then((res) => {
// res === true
});
Auto-gen a salt and hash:
bcrypt.hash('bacon', 8, function(err, hash) {
});
```
5.Install jwt (for json Web Token)
```shell
npm i jsonwebtoken
ex==//
const express = require('express');
const dotenv = require('dotenv');
const jwt = require('jsonwebtoken');
const app = express();
// Set up Global configuration access
dotenv.config();
let PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
console.log(`Server is up and running on ${PORT} ...`);
});
// Main Code Here //
// Generating JWT
app.post("/user/generateToken", (req, res) => {
// Validate User Here
// Then generate JWT Token
let jwtSecretKey = process.env.JWT_SECRET_KEY;
let data = {
time: Date(),
userId: 12,
}
const token = jwt.sign(data, jwtSecretKey);
res.send(token);
});
// Verification of JWT
app.get("/user/validateToken", (req, res) => {
// Tokens are generally passed in header of request
// Due to security reasons.
let tokenHeaderKey = process.env.TOKEN_HEADER_KEY;
let jwtSecretKey = process.env.JWT_SECRET_KEY;
try {
const token = req.header(tokenHeaderKey);
const verified = jwt.verify(token, jwtSecretKey);
if(verified){
return res.send("Successfully Verified");
}else{
// Access Denied
return res.status(401).send(error);
}
} catch (error) {
// Access Denied
return res.status(401).send(error);
}
});
```
## Fronted Install
# Getting Started with Create React App
This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
## Available Scripts
In the project directory, you can run:
### `npm start`
Runs the app in the development mode.\
Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
The page will reload when you make changes.\
You may also see any lint errors in the console.
### `npm test`
Launches the test runner in the interactive watch mode.\
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
### `npm run build`
Builds the app for production to the `build` folder.\
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.\
Your app is ready to be deployed!
See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
### `npm run eject`
**Note: this is a one-way operation. Once you `eject`, you can't go back!**
If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
## Learn More
You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
