class File

class File extends ServiceObject<File, FileMetadata> {}

A File object is created from your Bucket object using Bucket#file.

constructor(bucket: Bucket, name: string, options?: FileOptions);

Constructs a file object.
Parameter bucket
The Bucket instance this file is attached to.
Parameter name
The name of the remote file.
Parameter options
Configuration options.
Example 1
const {Storage} = require('@google-cloud/storage'); const storage = new Storage(); const myBucket = storage.bucket('my-bucket'); const file = myBucket.file('my-file');

property acl

acl: Acl;

property bucket

bucket: Bucket;

property cloudStorageURI

readonly cloudStorageURI: URL;

The object's Cloud Storage URI (gs://)

Example 1

const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const bucket = storage.bucket('my-bucket');
const file = bucket.file('image.png');

// `gs://my-bucket/image.png`
const href = file.cloudStorageURI.href;

property crc32cGenerator

property name

name: string;

property parent

        options?: CopyOptions
    ): Promise<CopyResponse>;

method createReadStream

createReadStream: (options?: CreateReadStreamOptions) => Readable;

Create a readable stream to read the contents of the remote file. It can be piped to a writable stream or listened to for 'data' events to read a file's contents.

In the unlikely event there is a mismatch between what you downloaded and the version in your Bucket, your error handler will receive an error with code "CONTENT_DOWNLOAD_MISMATCH". If you receive this error, the best recourse is to try downloading the file again.

NOTE: Readable streams will emit the end event when the file is fully downloaded.

Parameter options

Configuration options.

Returns

{ReadableStream}

Example 1

//-
// <h4>Downloading a File</h4>
//
// The example below demonstrates how we can reference a remote file, then
// pipe its contents to a local file. This is effectively creating a local
// backup of your remote data.
//-
const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const bucket = storage.bucket('my-bucket');

const fs = require('fs');
const remoteFile = bucket.file('image.png');
const localFilename = '/Users/stephen/Photos/image.png';

remoteFile.createReadStream()
  .on('error', function(err) {})
  .on('response', function(response) {
    // Server connected and responded with the specified status and headers.
   })
  .on('end', function() {
    // The file is fully downloaded.
  })
  .pipe(fs.createWriteStream(localFilename));

//-
// To limit the downloaded data to only a byte range, pass an options
// object.
//-
const logFile = myBucket.file('access_log');
logFile.createReadStream({
    start: 10000,
    end: 20000
  })
  .on('error', function(err) {})
  .pipe(fs.createWriteStream('/Users/stephen/logfile.txt'));

//-
// To read a tail byte range, specify only `options.end` as a negative
// number.
//-
const logFile = myBucket.file('access_log');
logFile.createReadStream({
    end: -100
  })
  .on('error', function(err) {})
  .pipe(fs.createWriteStream('/Users/stephen/logfile.txt'));

method createResumableUpload

        options: CreateResumableUploadOptions,
        callback: CreateResumableUploadCallback
    ): void;
    (callback: CreateResumableUploadCallback): void;
};

method createWriteStream

createWriteStream: (options?: CreateWriteStreamOptions) => Writable;

Create a writable stream to overwrite the contents of the file in your bucket.

A File object can also be used to create files for the first time.

Resumable uploads are automatically enabled and must be shut off explicitly by setting options.resumable to false.

There is some overhead when using a resumable upload that can cause noticeable performance degradation while uploading a series of small files. When uploading files less than 10MB, it is recommended that the resumable feature is disabled.

NOTE: Writable streams will emit the finish event when the file is fully uploaded.

See See

Parameter options

Configuration options.

Returns

{WritableStream}

Example 1

const fs = require('fs');
const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const myBucket = storage.bucket('my-bucket');

const file = myBucket.file('my-file');

//-
// <h4>Uploading a File</h4>
//
// Now, consider a case where we want to upload a file to your bucket. You
// have the option of using {@link Bucket#upload}, but that is just
// a convenience method which will do the following.
//-
fs.createReadStream('/Users/stephen/Photos/birthday-at-the-zoo/panda.jpg')
  .pipe(file.createWriteStream())
  .on('error', function(err) {})
  .on('finish', function() {
    // The file upload is complete.
  });

//-
// <h4>Uploading a File with gzip compression</h4>
//-
fs.createReadStream('/Users/stephen/site/index.html')
  .pipe(file.createWriteStream({ gzip: true }))
  .on('error', function(err) {})
  .on('finish', function() {
    // The file upload is complete.
  });

//-
// Downloading the file with `createReadStream` will automatically decode
// the file.
//-

//-
// <h4>Uploading a File with Metadata</h4>
//
// One last case you may run into is when you want to upload a file to your
// bucket and set its metadata at the same time. Like above, you can use
// {@link Bucket#upload} to do this, which is just a wrapper around
// the following.
//-
fs.createReadStream('/Users/stephen/Photos/birthday-at-the-zoo/panda.jpg')
  .pipe(file.createWriteStream({
    metadata: {
      contentType: 'image/jpeg',
      metadata: {
        custom: 'metadata'
      }
    }
  }))
  .on('error', function(err) {})
  .on('finish', function() {
    // The file upload is complete.
  });

//- // Continuing a Resumable Upload // // One can capture a uri from a resumable upload to reuse later. // Additionally, for validation, one can also capture and pass crc32c. //- let uri: string | undefined = undefined; let resumeCRC32C: string | undefined = undefined;

fs.createWriteStream() .on('uri', link => {uri = link}) .on('crc32', crc32c => {resumeCRC32C = crc32c});
