gridfs-promise

Known Vulnerabilities Build Status

This is a simple wrapper for the new MongoDB GridFSBucket-API (http://mongodb.github.io/node-mongodb-native/3.0/tutorials/gridfs/streaming/). The old GridStore-API is now deprecated (http://mongodb.github.io/node-mongodb-native/3.0/tutorials/gridfs/gridstore/).

How to install

That is simple

npm install gridfs-promise

Usage

const mongoOptions: MongoClientOptions = {
  autoReconnect: true,
  useNewUrlParser: true
};

let gridFS = new GridFSPromise("test", "mongodb://localhost:27017/test", mongoOptions, __dirname, "attachments");
gridFS.getObject("59e085f272882d728e2fa4c2").then((item) => {
    console.log(item);
}).catch((err) => {
    console.error(err);
});

Methods

uploadFileString

By this method you can simple upload files by a base64 string

gridFS.uploadFileString('R0lGODlhPQBEAPeoAJosM//AwO/AwHVYZ/z595kzAP/s7P+goOXMv8+fhw/v739/f+8PD98fH/8mJl+fn/9ZWb8/PzWlwv///6wWGbImAPgTEMImIN9gUFCEm/gDALULDN8PAD6atYdCTX9gUNKlj8wZAKUsAOzZz+UMAOsJAP/Z2ccMDA8PD/95eX5NWvsJCOVNQPtfX/8zM8+QePLl38MGBr8JCP+zs9myn/8GBqwpAP/GxgwJCPny78lzYLgjAJ8vAP9fX/+MjMUcAN8zM/9wcM8ZGcATEL+QePdZWf/29uc/P9cmJu9MTDImIN+/r7+/vz8/P8VNQGNugV8AAF9fX8swMNgTAFlDOICAgPNSUnNWSMQ5MBAQEJE3QPIGAM9AQMqGcG9vb6MhJsEdGM8vLx8fH98AANIWAMuQeL8fABkTEPPQ0OM5OSYdGFl5jo+Pj/+pqcsTE78wMFNGQLYmID4dGPvd3UBAQJmTkP+8vH9QUK+vr8ZWSHpzcJMmILdwcLOGcHRQUHxwcK9PT9DQ0O/v70w5MLypoG8wKOuwsP/g4P/Q0IcwKEswKMl8aJ9fX2xjdOtGRs/Pz+Dg4GImIP8gIH0sKEAwKKmTiKZ8aB/f39Wsl+LFt8dgUE9PT5x5aHBwcP+AgP+WltdgYMyZfyywz78AAAAAAAD///8AAP9mZv///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAKgALAAAAAA9AEQAAAj/AFEJHEiwoMGDCBMqXMiwocAbBww4nEhxoYkUpzJGrMixogkfGUNqlNixJEIDB0SqHGmyJSojM1bKZOmyop0gM3Oe2liTISKMOoPy7GnwY9CjIYcSRYm0aVKSLmE6nfq05QycVLPuhDrxBlCtYJUqNAq2bNWEBj6ZXRuyxZyDRtqwnXvkhACDV+euTeJm1Ki7A73qNWtFiF+/gA95Gly2CJLDhwEHMOUAAuOpLYDEgBxZ4GRTlC1fDnpkM+fOqD6DDj1aZpITp0dtGCDhr+fVuCu3zlg49ijaokTZTo27uG7Gjn2P+hI8+PDPERoUB318bWbfAJ5sUNFcuGRTYUqV/3ogfXp1rWlMc6awJjiAAd2fm4ogXjz56aypOoIde4OE5u/F9x199dlXnnGiHZWEYbGpsAEA3QXYnHwEFliKAgswgJ8LPeiUXGwedCAKABACCN+EA1pYIIYaFlcDhytd51sGAJbo3onOpajiihlO92KHGaUXGwWjUBChjSPiWJuOO/LYIm4v1tXfE6J4gCSJEZ7YgRYUNrkji9P55sF/ogxw5ZkSqIDaZBV6aSGYq/lGZplndkckZ98xoICbTcIJGQAZcNmdmUc210hs35nCyJ58fgmIKX5RQGOZowxaZwYA+JaoKQwswGijBV4C6SiTUmpphMspJx9unX4KaimjDv9aaXOEBteBqmuuxgEHoLX6Kqx+yXqqBANsgCtit4FWQAEkrNbpq7HSOmtwag5w57GrmlJBASEU18ADjUYb3ADTinIttsgSB1oJFfA63bduimuqKB1keqwUhoCSK374wbujvOSu4QG6UvxBRydcpKsav++Ca6G8A6Pr1x2kVMyHwsVxUALDq/krnrhPSOzXG1lUTIoffqGR7Goi2MAxbv6O2kEG56I7CSlRsEFKFVyovDJoIRTg7sugNRDGqCJzJgcKE0ywc0ELm6KBCCJo8DIPFeCWNGcyqNFE06ToAfV0HBRgxsvLThHn1oddQMrXj5DyAQgjEHSAJMWZwS3HPxT/QMbabI/iBCliMLEJKX2EEkomBAUCxRi42VDADxyTYDVogV+wSChqmKxEKCDAYFDFj4OmwbY7bDGdBhtrnTQYOigeChUmc1K3QTnAUfEgGFgAWt88hKA6aCRIXhxnQ1yg3BCayK44EWdkUQcBByEQChFXfCB776aQsG0BIlQgQgE8qO26X1h8cEUep8ngRBnOy74E9QgRgEAC8SvOfQkh7FDBDmS43PmGoIiKUUEGkMEC/PJHgxw0xH74yx/3XnaYRJgMB8obxQW6kL9QYEJ0FIFgByfIL7/IQAlvQwEpnAC7DtLNJCKUoO/w45c44GwCXiAFB/OXAATQryUxdN4LfFiwgjCNYg+kYMIEFkCKDs6PKAIJouyGWMS1FSKJOMRB/BoIxYJIUXFUxNwoIkEKPAgCBZSQHQ1A2EWDfDEUVLyADj5AChSIQW6gu10bE/JG2VnCZGfo4R4d0sdQoBAHhPjhIB94v/wRoRKQWGRHgrhGSQJxCS+0pCZbEhAAOw==', "test.gif", "image/gif", {}).then((result) => {
    console.log(result);
}).catch((error) => {
    console.error(error);
});

getObject

By this method you will simple get the meta-object from the MongoDB as a Promise-Object. If nothing found at the Database, then it will reject and the catch-block will be executed.

gridFS.getObject("59e085f272882d728e2fa4c2").then((item) => {
    console.log(item);
}).catch((err) => {
    console.error(err);
});

getFile

You will get the file simple written to the filesystem directly from the Database. If nothing found at the Database, then it will reject and the catch-block will be executed.

gridFS.getFile("59e085f272882d728e2fa4c2", "test.gif").then((item) => {
    console.log(item);
}).catch((err) => {
    console.error(err);
});

getFileStream

You will get a GridFSBucketReadStream as Promise. If nothing found at the Database, then it will reject and the catch-block will be executed.

This method is very useful, to stream the content directly to the user.

For example with express:

return gridFs.getFileStream(req.params.id).then((item) => {
                item
                .once("error", () => {
                    return res.status(400).end();
                }).pipe(res);
        }).catch(() => res.status(500));

Mongoose & Other MongoClient Connections

You can use you already existing MongoDB connection with the library.

const mongoDBConnection = await MongoClient.connect('mongodb://localhost:27017');

const test = new GridFSPromise('test');
test.CONNECTION = mongoDBConnection;

Use GridFS Promise together with NestJS

It is really simple to use GridFS Promise together with NestJs.

Install the dependency via npm install gridfs-promise --save.

In the Module where you want to use GridFS create a simple Provider to Load the Lib

// sample.module.ts
providers: [{
    provide: GridFSPromise,
    useFactory: async (configService: ConfigService) => {
      return new GridFSPromise(configService.getString('DB_NAME'), configService.getString('DB_URL'));
    },
    inject: [ConfigService],
  }]
