file-api-mongodb

Store files in MongoDb accessed through an express middleware.

const {multerUpload} = require("file-api-mongodb");

const {upload, storage } = multerUpload({bucketName : 'darbyBucket'});
// It's very crucial that the file name matches the name attribute in your html
appRouter.post('/', upload.single('myFile'),
    (req, res) => {
    //the successful result of the file upload is in "fileData" field.
    res.json(req.fileData);
});

appRouter.get('/', (req,res) => {
    storage.getFileList(res);
});

appRouter.get('/:fileName', (req,res) => {
    storage.getFile(res, req.params.fileName);
});

appRouter.get('/id/:id', (req,res) => {
    storage.getFileById(res, req.params.id);
});

appRouter.delete('/:id', (req,res) => {
    storage.deleteFile(req.params.id, (err) => {
        if(err)
            res.status(500).send(err.message);
        else
            res.status(204).send();
    });
});

To scale an image that is being uploaded, set the request parameter "imageWidth"

appRouter.post('/image/:imageWidth', upload.single('myFile'),
    (req, res) => {
        res.json(req.fileData);
    });
