HOW TO uplode and save the img in database

Copy link


You need to look in that line of code . Here you can select your upload folder.

``app.use(express.bodyParser({ keepExtensions: true, uploadDir: __dirname + '/public/uploads'}));

Copy link

you just save the location img in database not the img

the code can't be run

Cannot read property 'xxxxx' of undefined

To access the file property, do this

var getfile = JSON.stringify(files);

This will make it a JSON object.


You will see the file is now accessible and you can use it. To test it, use


Now you can access it, you cannot use it. You have to convert it from a JSON object to a javascript object. Use

var file = JSON.parse(getfiles)

You code is ready to serve you now.

Why does the path to the routes dependency start with ./ but non of the other dependencies have that?
I'm guessing the code is a little dated now? I can't get it to run because when I install routes with npm there are no user or common directories in it:

Error: Cannot find module 'routes/user'
