13. Advanced Javascript

Variable declaration:

  • let variableName (new in ECMAScript 6) /* its value can be altered
  • const variableName (new in ECMAScript 6) /* it stands for constant, its value can't be altered once declared
  • `` /* are used instead of '' or "". Allows us to avoid the "+" separation and elements and variables should be added with syntax ${element}
  • a**b /* it stands for a to the b potence
  • element.padStart(param1,param2) /* param1 number of characters param2 are added before the value of element declared. The default param2 is " "
  • .padEnd(param1,param2) /* Same as above but at the end
  • .trimStart() /* eliminates empty spaces from the start of a variable
  • .trimEnd() /* Same as above but from the end
  • debugger; /* Stops running the code and opens console for a step by step check

Functions:

  • Function declaration syntax: const functionname=(param1,param2...) => action /* If there is an only return, there is no need to type "return" and if it's just one parameter, no need to add "()"
  • Currying: const functionname= param1 => param2 => action /* To properly call function syntax is: functionname (param1)(param2)
  • Compose: const functionname= (param2,param3) => param1 => param2(param3(param1)) /* Being param2 and 3 functions y param1 a value. Executes a function inside a function executed with the initial param1

Arrays:

  • array.forEach(num=>{}) /* For each element num of the array, executes the actions inside {}
  • array.map(num=>{}) /* For each element num in the array, executes actions inside {} and return needs to be specified since the return will be placed in a new array.
  • array.filter(num=>{}) /* For each element num of the array a condition is checked. If the value turns out true, it will be added to teh new array. Return needs to be specified
  • array.reduce((accumulator,num)=>{}, param3) /* Acumulates values of the operation performed in previous elements, param3 beinf the initial value of the acumulator
  • array.concat(param1) /* Concats param1 to the array
  • array.includes('param1') /* Verifies the array includes param1
  • array.flat(param1) /* Elminates the nested arrays to a param1 level
  • array.flatMap(param1=>{}) /* For each element num, the operation inside {} is performed and the array is lowered to a level 1 nesting
  • array.fromEntries /* Turns the array into an object, making the first element of the array the property and the second the value of such property

Objects:

  • const(/let) {property1, property2,...} = obj /* Given an object obj, keeps the value of the properties in new variables property1, property2,...etc
  • {...obj} /* Creates a clone object of the object obj
  • Object.assign(param1,param2) /* Clones the lements of an object param2 in an object param1
  • Object.values(obj) /* Takes the values of the properties of an object obj
  • Object.entries(obj) /* returns an array with property,value of each element of an object obj
    /* .entries and .values can be used with array methods such as .map, .forEach, etc.
  • this: When using this parameter, the method/action is applied exclusively to the element in which "this" has been summoned.

Class:

  • Class creator syntax: Classname {
        constructor (param1,param2){
          this.param1= value;
          this.param2= value2;
        }
        classmethod(){
        }
    }

  • Create class object syntax: new Classname(param1,param2)

  • Class extention syntax: Classextension extends Classname{
        constructor(param1,param2){
        super(param1,param2)
        }
        classextensionmethod(){
        }
    }

/* You utilize a class when we are planning to create several objects with similar propperties
/* A class extention is used when those several objects can contain properties or categories with specific properties and methods, while respecting the initial constructor.

Loops:

  • for of: for (param1 of array){} /* It's a for loop in an array and an action over the element number param1 in an array array
  • for in: for (param1 in obj) {} /* It's a for loop of the properties and an action over the property number param1 in an object obj

/* both arrays and strings are iterable in JS
/* for of cannot be used in objects, but for in can be used in arrays, you get the index number as a return

14. Command Line

FOR MAC OR LINUX:

cd .. - go up a level
mkdir {file name} - make a directory
echo > {filename} - create an empty file
del {filename} - remove a file
rmdir {directory name} - remove a directory and all files within
rename {filename} {new filename} - rename a file or folder
start {filename} - open file in default program
start . - open current directory
cls - clear the terminal screen

15. Developer Environment

Popular code editors:

16. Git + Github + Open Source Projects

Install Git:

git clone “https:……”
git status
git add “filename”
git add .
git commit –m”message”
git push
git pull
git branch
git branch “name”
git checkout “name”
git merge “name”

Once you are in your forked project directory in your command prompt....

  1. Type git remote -v and press Enter. You'll see the current configured remote repository for your fork.

    a. git remote -v

    b. origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)

    c. origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)

  2. Type git remote add upstream, and then paste the URL you would copy from the original repository if you were to do a git clone. Press Enter. It will look like this:

    git remote add upstream https://github.com/zero-to-mastery/PROJECT_NAME.git

  3. To verify the new upstream repository you've specified for your fork, type git remote -v again. You should see the URL for your fork as origin, and the URL for the original repository as upstream.

  4. Now, you can keep your fork synced with the upstream repository with a few Git commands. One simple way is to do the below command from the master of your forked repository: git pull upstream master

25. FINAL PROJECT: SmartBrain Back-End -- Server

Change localhost:

If you don't want set environment variable, other option - modify scripts part of package.json from:

"start": "react-scripts start"

Linux (tested on Ubuntu 14.04/16.04) and MacOS (tested by @aswin-s on MacOS Sierra 10.12.4) to:

"start": "PORT=3006 react-scripts start"

or (maybe) more general solution by @IsaacPak to:

"start": "export PORT=3006 react-scripts start"

Windows @JacobEnsor solution to:

"start": "set PORT=3006 && react-scripts start"

Front-end and back-end connection:

Front-end:

fetch('http://localhost:3000/image', {
	method: 'put',
	headers: {'Content-Type': 'application/json'},
	body: JSON.stringify({
		id: this.state.user.id
	})
})
.then(response => response.json())
.then(count => {
	this.setState(Object.assign(this.state.user, { entries:count}))
})

Back-end:

const cors = require('cors')
app.use(cors());

26. Databases

Install PostgreSQL:

data types

Terminal commands for windows:

Login: (-U usuario)

psql -h localhost -U postgres

Create database:

create database database_name;

Show all datatables:

\l

Create a user:

create user moni with password ‘moni’;

Delete a database:

drop database database_name;

Connect to a database:

\c database_name;

Create a schema:

create schema friends;

Create a table:

create table Friends.test( firstname CHAR(15), lastname CHAR(20));

create table Friends.login(id serial not null primary key, secret varchar (100) not null, name text unique not null, entries bigint default 0, joined timestamp not null);

Show all information of a table:

select * from friends.test;

Describe database:

\d friends.test

Insert data:

insert into friends.test values( ‘Mike’, ‘Smith’);

insert into friends.test (firstname, lastname )values( ‘Sally’, ‘Jones’);

Add a column to an existing table:

alter table Friends.test add age smallint;

Update data from the table:

update friends.test set age = 25 where firstname= ‘Mike’;

Delete data from the table:

delete from friends.test where firstname = ‘Mike’;

Delete column from a table:

alter table friends.test drop column age;

Delete a table:

drop table friends.test;

Functions:

select avg(age) from friends.test;

Join tables:

select * from friends.test join friends.login on friends.test.firstname = friends.login.name;

Exit:

\q

List all users in postgresSQL database server:

\du

List all tables in a schema:

\d+ schema_name.*

List all tables in a database:

\dt *.*

List a table in a schema:

\d+ schema_name . table_name

Show description of a table, columns, type, modifications, etc.:

\d+ table_name

Create a backup of a database:

pg_dump -h localhost -U postgres database_name > database_name.sql

Restore a database: 1. Create a new database where the restore file is going to be placed:

psql -U postgres -d new_database_name -f respaldo.sql

*Note:  it is important to create the restore in the same root where the database copy is saved.

Enter to postgres with a user different to postgres:

psql -h localhost -d postgres -U usuario

Enter to a database with a different user:

psql -h localhost -d nombre_base -U nombre_usuario

27. FINAL PROJECT: SmartBrain Back-End – Database

Tool for db connection with back-end:

28. Production + Deployment

Environmental variables:

PORT

On terminal:

bash
-->PORT-3000 node server.js

On server.js:

	const PORT = process.env.PORT
	app.listen(PORT, ()=>{
		console.log(`app is running on port ${PORT}`);
	})

DATABASE

On terminal:

bash
-->DATABASE_URL-123  node server.js

On server.js:

	const DATABASE_URL = process.env. DATABASE_URL
	app.listen(3000, ()=>{
		console.log(`app is running on port ${ DATABASE_URL }`);
	})

OTHER OPTION

On terminal:

fish
-->env DATABASE_URL-‘hello’ node server.js

Deploy apps:

Heroku:

Not the best one:

Commands for heroku on backend folder: Install heroku:

npm install -g heroku
heroku login
heroku create

In the terminal there will be a URL : ” https://limitless-bastion-10041.herokuapp.com/”

git remote –v
git push origin master
heroku git: remote –a limitless-bastion-10041

Changes required in:

  • BACK END: PORT in server.js needs to be changed by an environment variable
  • FRONT END: fetch URL needs to be changed by the URL of HEROKU + “:3000”
git push heroku master
for checking errors:
heroku logs --tail
heroku open

Connect to pg database:

Create a new postgres database using Heroku:

Data: Heroku postgres: create new: install heroku postgres: select the app created

heroku addons
