-
Then create a new table name
users, contain following fields.{ "username": "", "email": "", "password": "", "role": "" }
You can open
postmanand paste this api endpoint into the url sectionhttp://localhost:5000/api/v1/usersAfter that select
bodyand alsojsonas format and paste that object, usedbcryptto encrypt password{ "username": "Minhazul Abedin Munna", "email": "[email protected]", "password": "1234", "role": "admin" }
Now select
POSTmethod and hitsendbutton, It will successfully create a user. -
Goto this project directory & open terminal
npm run start:dev- Now project will run in following port
http://localhost:5000API Endpoints
http://localhost:5000/api/v1/http://localhost:5000/api/v1/users- Create any module by this command
npm run create-module moduleNameDeleting a Module by following this command
npm run delete-module moduleName- If you want to delete any module , just delete the module form
src/app/modules/moduleNameand also delete the route fromsrc/app/routes/index.tsfile.
- Just run the following command, This will generate the
distdirectory. Which you can deploy to the server.
npm run build- After getting the
distdirectory, you can run the following command
npm run start:prodYou can check whether your project is working perfectly for the production level or not.
- File upload configured with Multer, cloudinary, imgbb
- Payment gateway configured with sslcommerze, paypal & stripe
- Organized file with modular approach (controller, service, route, interface)
- Socket.io configured for real time communication
- MongoDB configured
- Mail Server configured with Node Mailer
- Query Builder configured
- Make a route this way:
import multer from 'multer';
// File uploading configuration..
const upload = multer()
router.post('/up/file', upload.single('photo'), userController.testUpload); //single file upload
router.post('/up/file', upload.array('photo'), userController.testUpload); //multiple file upload
router.post('/up/file', upload.array('photo',10), userController.testUpload); //specific limit file upload- Controller methods will be this way:
const testUpload = async (req: Request, res: Response, next: NextFunction) => {
try {
const file = req.file as Express.Multer.File;
if (!file) {
return res.status(400).json({ message: 'No file uploaded' });
}
// Check file size condition first before proceeding with upload
if (file.size > 10 * 1024) { // 10KB = 10 * 1024 bytes
return res.status(400).json({ message: `File ${file.originalname} exceeds 10KB, cannot be uploaded` });
}
// Check file type (only jpg and png are allowed)
const allowedMimes = ['image/jpeg', 'image/png'];
if (!allowedMimes.includes(file.mimetype)) {
return res.status(400).json({ message: `Invalid file type. Only JPG and PNG files are allowed.` });
}
// Save the file and get its URL
const folderPath = 'absk/ads';
let fileURL: string;
try {
fileURL = saveFile(file.buffer, file.originalname, folderPath, req);
} catch (error: any) {
return res.status(500).json({
message: `Failed to upload file ${file.originalname}: ${error.message}`,
});
}
// Respond with success message if file is uploaded successfully
res.json({
message: 'File uploaded successfully',
fileURL,
});
} catch (error) {
next(error); // Pass any errors to the error-handling middleware
}
};- For uploading multiple files, then follow this process
try {
const files = req.files as Express.Multer.File[];
if (!files || files.length === 0) {
return res.status(400).json({ message: 'No files uploaded' });
}
// Check file size condition first before proceeding with uploads
const errors: string[] = [];
// Check each file
for (const file of files) {
if (file.size > 10 * 1024) { // 10KB = 10 * 1024 bytes
errors.push(`File ${file.originalname} exceeds 10KB, cannot be uploaded`);
}
}
// If there are any errors, reject the upload and don't save any files
if (errors.length > 0) {
return res.status(400).json({
message: 'Some files failed to upload',
errors,
});
}
// Array to store the URLs of successfully uploaded files
const fileURLs: string[] = [];
// If all files pass the size condition, proceed with the upload
for (const file of files) {
// Save the file and get its URL
const folderPath = 'uploads/photos';
try {
const fileURL = saveFile(file.buffer, file.originalname, folderPath, req);
fileURLs.push(fileURL);
} catch (error: any) {
errors.push(`Failed to upload file ${file.originalname}: ${error.message}`);
}
}
// If there are still errors, return them
if (errors.length > 0) {
return res.status(400).json({
message: 'Some files failed to upload',
errors,
});
}
// Respond with success message if all files were uploaded successfully
res.json({
message: 'Files uploaded successfully',
fileURLs,
