Then, we loop over the binary data buffer in chunks of chunkSizeBytes bytes and generate an array chunk that contains an object for each chunk.įor (var i = 0 i < data. This folder will be transformed into a workspace, containing all of the code files contained within it. Launch the VSCode editor and navigate to this folder. In the next stage, we declare the chunkSizeBytes variable, which is the size in bytes for each chunk of the image file data. MongoDB with MongoDB Compass VS Code Step 1: Make a folder named mongogrid. Var data = fs.readFileSync('G:\StudentImage.png') If you need to store files larger than that then you can use GridFS. GridFS allows you to store and retrieve files, which includes ones exceeding the BSON-document size limit of 16 MB. As you’ve likely discovered, there is a 16 MB size limit for MongoDB documents. MongoDB has a driver specification to upload and retrieve files from it called GridFS. Then, creates a new ObjectId that is used to identify the image file specifically. Storing large files in a database is always a contentious topic, but I’ll skip over that. Next, we read the contents of the image file from the disk using the fs.readFileSync() method. MongoDB Many applications involve file management and have file storage as an important feature for enhancing data processing. # Storing the specific image in the bucket Classified as a NoSQL database program, MongoDB uses JSON-like documents. Here, we have created the file object that is specified with metadata for the image file StudentImage.png. MongoDB is a source-available cross-platform document-oriented database program. This data type corresponds to the RDBMS BLOB (binary large object) type, and its. Unlike traditional relational DBMSs, which store data in tables consisting of rows and columns, MongoDB stores data in JSON-like structures referred to as documents. Moreover, using the GridFS MongoDB’s GridFS is a file storage system that allows us to store large files, including images.įor example, in the initial step, we stored the specific image in the bucket by using the following MongoDB query. In MongoDB, you can use the BSON binary type to store any kind of binary data. MongoDB is a document-oriented NoSQL database management system (DBMS).
