Created a basic application using NodeJS and Express

Acquired knowledge:

• Requests POST, GET, PUT and DELETE;
• Middlwares (for specific requests and global);
• Response using status errors;

The MeetApp is an app that aggregates events for developers (Meetup + App). In this challenge were created some basic features that I have learned throughout the classes so far.

Used tools

• Sucrase + Nodemon;
• ESLint + Prettier + EditorConfig;
• Sequelize (PostgresSQL);
• Docker;

Features

    Authentication

        Allow a user to authenticate to your application using email and password.

• Authentication using JWT;
• Input validations using Yup;

    Registration and updating of users

       Allow new users to sign up for your application using name, email and password. To update the password, the user must also submit a             confirmation field with the same password.

• The password must be encrypted;
• Input validations using Yup;

Objective: Enhance the Meetapp started in the previous challenge by implementing new features

Used tools

• Sucrase + Nodemon;
• ESLint + Prettier + EditorConfig;
• Sequelize (PostgresSQL);
• Docker (postgres and sentry);
• Multer (file upload);
• Nodemailer (for sending emails);
• Mailtrap (test sending emails in development environment);
• Redis + Bee Queue (manage email queue);
• Sentry (monitor production errors) + Youch (prettier error json);
• Dotenv (environment variables);

Features

Image upload

Create a meetup with a picture. Was created a route to upload an image using the Multer library.

Sending e-mails

Whenever a user signs up to meetup, an email will be sent to the organizer containing the data related to the registered user. Multer library was used to send emails to a test e-mail (MailTrap).

E-mail Queue

An e-mail queue system (Redist + Bee Queue) was used preventing it from interfering with application performance.

Error handling

To monitor errors in production, the Sentry library was used. The Youch was used to return a json containing error details in development environment.

Enviorment variables

The library Dotenv was used to creating and using a file containing all environment variables.

Objective: Create a simple application (Dogbook) using ReactJS with a graphical user interface similar to Facebook. The information on the page is static and does not use REST API or backend.

Application

The Dogbook is a simple page similar to Facebook using ReactJS components to represent the header, post list, post, and comments.

Used tools

• ReactJS;
• Webpack;
• Babel;
• Webpack Dev Server;

BALM is an ERP software that helps in document control. I'm responsible to recreate many pages using good practices, to create components that match the situation.

• My biggest achievement was improving the performance of a query, it was taking too long to query with a large amount of data. I also restructured several system pages using components that matched each situation.
• I was able to persuade the team to positively evade the visual standard of the system by modernizing, inventing, or using components that fit the situation, providing a good user experience.

This project is a personal project that I'm developing for my friends. Is an app that shows many data collected from different websites using web scraping (python). This application contains 3 spiders (bots) that collect data (from 3 websites) periodically using Scrapy (python) and save the data to a Mongo database.
