Backend Development using TypeScript and Express:
TypeScript and Express:
Develop a server using Express and TypeScript for backend applications (K9, S1, S11, S12) RESTFUL APIs: Construct and implement RESTful APIs effectively (S1, S11, S12, S16)
Evidence:
Database schema design (
app.delete('/questions/:id', async (req: Request, res: Response) => {
let id = req.params.id;
let deleteData = await fsPromises.readFile(library, 'utf8');
let jsonDeleteData = JSON.parse(deleteData);
let questionYass = jsonDeleteData.questions.filter(
(question: Question) => question.id === parseInt(id)
);
if (questionYass.length > 0) {
try {
let qMatch = jsonDeleteData.questions.filter(
(question: any) => question.id !== parseInt(id)
);
let updatedJsonString = JSON.stringify({ questions: qMatch }, null, ' ');
await fsPromises.writeFile(library, updatedJsonString);
console.log('the question has been deleted');
res.send({ message: 'question has successfully been deleted' });
} catch (err) {
console.log(err);
}
} else {
console.log('please revise question id');
res.send({ message: 'please revise question id' });
}
});

Node File System:
One of the areas I struggled with is using the Node File System (fs) to set up an interim database. While I managed to get basic operations working, I encountered challenges related to error handling, performance optimization, and ensuring data consistency.
Evidence:
CRUD operations implementation (
app.put('/reset', async (req: Request, res: Response) => {
try {
let reWriteData = await fsPromises.readFile(library, 'utf8');
let jsonReWriteData = JSON.parse(reWriteData);
// Loop through each question and reset properties
let parsedJsonReWriteData = jsonReWriteData.questions.map(
(question: any) => ({
...question,
favourited: false,
completed: false,
})
);
// Rewrite database with updated data
let addingFalse = JSON.stringify(
{ questions: parsedJsonReWriteData },
null,
2
); // Assuming "questions" is the key for your array of questions
await fsPromises.writeFile(library, addingFalse);
res.send({ message: 'Favourite has been reset & Completed been reset' });
} catch (error) {
console.error('Error occurred while resetting favourite:', error);
res
.status(500)
.send({ message: 'Error occurred while attempting to reset favourite' });
}
});
)

[What went well]
Made good progress in designing and implementing the database schema and CRUD operations. React components and state management and use of useContext API.
[Even better if] Improve your testing skills by writing more comprehensive tests and increasing test coverage.
