Cleanup Temporary Files
The cleanupTemporaryFiles
function is essential in handling a specific scenario in server management. When using uploadImagesToCloudinary
for image uploads, it also cleans up any temporary files. However, there may be cases where your server logic returns a response before reaching the uploadImagesToCloudinary
function, usually due to certain conditions not being met. In such situations, temporary files might still linger on the server. cleanupTemporaryFiles
is designed for these instances, ensuring that any unwanted temporary files are removed, thus maintaining server efficiency and avoiding clutter.
Example
Imagine a scenario where you're uploading a file but need to check certain conditions first. If these conditions aren't met, you'd typically send back an error response. Before sending this response, you use cleanupTemporaryFiles
to remove any files that were temporarily uploaded during the request process. This ensures your server remains clean and efficient, even when the usual upload and cleanup process is interrupted.
// import express and anything else that you need
// import "cleanupTemporaryFiles" & "uploadImagesToCloudinary" from 'express-cloudinary-image-handler'
app.post('/upload-file', async (req, res) => {
// condition check before uploading
if (!isConditionMet(req)) {
// If condition is not met, cleanup temporary files
await cleanupTemporaryFiles({ req: req })
// Send a response indicating the failure of condition
return res.status(400).json({ message: 'Required condition not met' })
}
// If condition is met, the flow would normally proceed to 'uploadImagesToCloudinary' util
// ... code to upload image using 'uploadImagesToCloudinary'
})
