MERN on Book Search Engine is a fully functioning Google Books API search engine built with a RESTful API, and refactored to be a GraphQL API built with Apollo Server. This project was built to practice the MERN stack, with a React front end, MongoDB database, and Node.js/Express.js server and API. It solves the problem of wanting to search for new books to read so that a list of books can be saved to purchase. Some things learned throughout MERN on Book Search Engine were understanding the convenience of having mutations that modify the data on the server so that the client can learn about those modifications, input type in a GraphQL schema is a special object type that groups a set of arguments together and can then be used as an argument to another field, ApolloProvider wraps the application and places the client on the context allowing access to it from anywhere in the component tree, and useEffect is a convenient React hook that can save objects to local storage.
Within the main directory, install dependencies by running "npm i' within the terminal of the main directory. This will install all the necessary dependencies needed for React, Vite, and Apollo Server to run. Then, connect to the client with the command "npm run start." Connect to both the API Server running on client-side and GraphQL running on server-side by running "npm run develop" within the terminal.
To run this application from the terminal, enter "npm run start" to start the server. The message "Local: http://localhost:3000" will display within the console. Vite will instantly start the server using the current working directory as a root. Once the application is loaded, a homepage will be displayed containing a search bar for searching books and a navigation bar featuring "Search For Books" and "Login/Sign Up" links.
When logged out, enter a title or author in the "Search for Books!" field and click "Submit Search." A new page will open with several search results, each featuring a book's title, author, description, image, and a "Link" button link to that book on the Google Books site. After clicking on the Login/Sign Up menu option, a modal appears on screen with a toggle between the option to Login or Sign Up. When the toggle is set to Sign Up, inputs for unsername, email, and password are displayed with a "Submit" button. When the toggle is set to Login, inputs for email and password are displayed with a "Submit" button. An account will be created and logged into after entering a username, valid email, password, and clicking "Submit."
Once logged in, the modal dissapears and navigation links for "Search for Books" and "See Your Books" appears as well as "Logout." Searching for title or author while logged in opens up a page with the same search results as before with the added "Save this Book!" button. When clicking "Save this book!," that book's information is saved to the account denoted by the button now displaying "This book has already been saved!" Clicking "See Your Books" brings up a Saved Books page with all of the books saved to the account, each featuring the same results from the Search Books page. To remove a book from the Saved Books list, click the "Delete this Book!" button. When finished with session, click "Logout" from the navigation bar.
For usage instructions with the deployed application using Render, follow the previous instructions after the application is loaded.
