Installation

Steps to setup minio on linux server - link

Node-Minio supports stable versions of Node.js 8.11.0 and later. You can install Node Minio in your project's node_modules folder.

To install the latest version on npm locally and save it in your package's package.json file:

npm install --save node-minio

Usage

• Initialize Minio Object

  const NodeMinio = require('node-minio');
 
  const config = {
      minio: {
        endPoint: "192.168.23.100",
        accessKey: "SN8JBGY43WPMFT0R56fsdfdsf",
        secretKey: "fdfdfdfd+3R9e/x4V0F6Xpjtfdsfd",
        secure: false,
        port: 8000,
      },
      errorFileUrl: "/sample/errorfile.pdf",
      bucket: "sample"     
  }
 
  const Minio = new NodeMinio(config);

• Upload a base64 file to Minio Bucket using NodeJS

  async function uploadFile(file) {
      const { base64: base64String, filename } = file;
      const extension = filename.split('.').pop();
      const fileName = moment().format('YYYY_MM_DD_hh_mm_ss_a');
      const object = `sampleFile/${fileName}.${extension}`;
 
      await Minio.base64Upload({ object, base64String });
      return object;
  }

• Generate dynamic URL with expiry to access file from bucket

   
    async function viewFile(fileName) {
       const filePath= 'sampleFile/${fileName}.pdf'
       const url = await Minio
        .viewLink({
          object: filePath,
        }, false);
      return url;
    }

• Lists all the directories in current folder/bucket

    async function listFilesList() {
       const baseUrl= 'sampleFile/'
       const fileList = await Minio
        .listDirectoryObjects({ object: baseUrl });
      return fileList;
    }

• Download a file from bucket

    async function downloadFile(req, res, name) {
            const file = {
                object: 'sampleFiles/',
                name: `${name}_${
                  moment().format('YYYY-DD-MM')}.${ext}`,
              };
             
            return Minio.downloadLinkBase(file)
                .then(downloadLink => res.redirect(downloadLink));
}

• Validate bucket and Download a file from bucket

    async function ValidateAndDownloadFile(req,res,name) {
            const file = {
                object: 'sampleFiles/',
                name: `${name}_${
                  moment().format('YYYY-DD-MM')}.${ext}`,
              };
             
            return Minio.downloadLink(file)
                .then(downloadLink => res.redirect(downloadLink));
}

• Used to retry alternative file to be downloaded. Here in tha example below we dont get original file than we search for -rst file and try download it

    async function retryFileFromMinio(fileName) {
       const retryObject = fileName.path.toLowerCase();
       const name = `${fileName}.pdf`.replace(/ /g, '_');
      
     const url = await Minio
      .retryDownloadLink({
      name,
      retryObject,
      object: retryObject.replace(/\.pdf$/g, '-rst.pdf'),
    });
}

• Generates and returns presigned URL for HTTP PUT operations. Clients may point to this URL to upload objects directly to a bucket even if it is private. This presigned URL can have an associated expiration time in seconds after which the URL is no longer valid. The default value is 7 days.

    async function getUploadLink() {
           const url = await Minio
            .uploadLink({});
          return url;
}

• Uploads base64 file from temp path(specified path) to bucket

    async function uploadFromTemp(file) {
           const extension = (file.name || file.filename).split('.').pop().toLowerCase();
                     minioObject = {
                       base64String: file.base64,
                       temp: file.path,
                       object: `sample/${Id}/${Id
                       }_${moment().format('DD-MM-YYYY_hh-mm-ss-a')}.${extension}`,
                     };
               const out = await Minio
                .uploadTemp(minioObject);
               return out;
}

• Uploads multiple base64 file in one go

  return Minio.base64UploadMulti(minioObjects);

• Copies file from one bucket to another

  return Minio.customCopyObject(minioObject);

• Gets object from minio bucket as a stream

  return Minio.getFileStream(minioObject);
