This is a frontend aplication to the backend developer job in the company Credere. To see it running in production, click here.
The backend repository can be found here.
This project was built using ReactJs with Typescript.
Here, node version is 12.16.3 and the package manager used is yarn in version 1.22.5.
The database used is Postgres with Typeorm as ORM (object-relational mapping). Besides that, the database is running in a docker image of postgres.
It's not used tests because the main point of this test is the backend application of this project.
After downloading the code from the repository (and letting the docker running), run yarn to install all the dependencies.
After that:
yarn start
The application will be running on port 3000:
http://localhost:3000
The project is about moving a Mars Probe in a console. It moves always to its front, but the direction may change from Right to Up, Down and Left. It runs only in small area like this:
| (0,4) | (1,4) | (2,4) | (3,4) | (4,4) |
|---|---|---|---|---|
| (0,3) | (1,3) | (2,3) | (3,3) | (4,3) |
| (0,2) | (1,2) | (2,2) | (3,2) | (4,2) |
| (0,1) | (1,1) | (2,1) | (3,1) | (4,1) |
| (0,0) | (1,0) | (2,0) | (3,0) | (4,0) |
These are the real coordinates and they are part of the probe localization. It accepts the written commands GE (Rotate Left), GD (Rotate Right) and M (Move Front).
More instructions may be seen inside the application (everything is in portuguese).
