Files for Meteor.js

ToC:

Award winning, extremely fast and robust package for file uploading, managing and streaming (Audio & Video & Images), with support of server's file system (FS) or third party storage, like: AWS, DropBox, Google Storage, Google Drive, GridFS or any other with API.

Upload, Download, Serve and Stream files within your Meteor application. Without system dependencies, try demo app, which works smoothly on free/sandbox Heroku plan, one click Heroku deploy

Why Meteor-Files?

Installation:

meteor add ostrio:files

ES6 Import:

import { FilesCollection } from 'meteor/ostrio:files';

FAQ:

  1. Where are files stored by default?: by default if config.storagePath isn't passed into Constructor it's equals to assets/app/uploads and relative to running script:
    • a. On development stage: yourDevAppDir/.meteor/local/build/programs/server. Note: All files will be removed as soon as your application rebuilds or you run meteor reset. To keep your storage persistent during development use an absolute path outside of your project folder, e.g. /data directory.
    • b. On production: yourProdAppDir/programs/server. Note: If using MeteorUp (MUP), Docker volumes must to be added to mup.json, see MUP usage
  2. Cordova usage and development: With support of community we do regular testing on virtual and real devices. To make sure Meteor-Files library runs smoothly in Cordova environment β€” enable withCredentials; enable {allowQueryStringCookies: true} and {allowedOrigins: true} on both Client and Server. For more details read Cookie's repository FAQ
  3. How to pause/continue upload and get progress/speed/remaining time?: see Object returned from insert method
  4. When using any of accounts packages - package accounts-base must be explicitly added to .meteor/packages above ostrio:files
  5. cURL/POST uploads - Take a look on POST-Example by @noris666
  6. In Safari (Mobile and Desktop) for DDP upload streams are hard-coded to 1 and chunk size is reduced by algorithm, due to error thrown if too many connection is open by the browser or frame is too big. Limit simultaneous uploads to 6 is recommended for Safari. This issue should be fixed in Safari 11. Switching to http transport (which has no such issue) is recommended for Safari. See #458
  7. Make sure you're using single domain for the Meteor app, and the same domain for hosting Meteor-Files endpoints, see #737 for details
  8. When proxying requests to Meteor-Files endpoint make sure protocol http/1.1 is used, see #742 for details

Shared code:

import { Meteor } from 'meteor/meteor';
import { FilesCollection } from 'meteor/ostrio:files';

const Images = new FilesCollection({
  collectionName: 'Images',
  allowClientCode: false, // Disallow remove files from Client
  onBeforeUpload(file) {
    // Allow upload files under 10MB, and only in png/jpg/jpeg formats
    if (file.size <= 10485760 && /png|jpg|jpeg/i.test(file.extension)) {
      return true;
    }
    return 'Please upload image, with size equal or less than 10MB';
  }
});

if (Meteor.isClient) {
  Meteor.subscribe('files.images.all');
}

if (Meteor.isServer) {
  Meteor.publish('files.images.all', function () {
    return Images.find().cursor;
  });
}

insert(settings[, autoStart]) [Client]

Read full docs for insert() method

Upload form (template):

<template name="uploadForm">
  {{#with currentUpload}}
    Uploading <b>{{file.name}}</b>:
    <span id="progress">{{progress.get}}%</span>
  {{else}}
    <input id="fileInput" type="file" />
  {{/with}}
</template>

Shared code:

import { FilesCollection } from 'meteor/ostrio:files';
const Images = new FilesCollection({collectionName: 'Images'});
export default Images; // To be imported in other files

Client's code:

import { Template }    from 'meteor/templating';
import { ReactiveVar } from 'meteor/reactive-var';
Template.uploadForm.onCreated(function () {
  this.currentUpload = new ReactiveVar(false);
});

Template.uploadForm.helpers({
  currentUpload() {
    return Template.instance().currentUpload.get();
  }
});

Template.uploadForm.events({
  'change #fileInput'(e, template) {
    if (e.currentTarget.files && e.currentTarget.files[0]) {
      // We upload only one file, in case
      // multiple files were selected
      const upload = Images.insert({
        file: e.currentTarget.files[0],
        streams: 'dynamic',
        chunkSize: 'dynamic'
      }, false);

      upload.on('start', function () {
        template.currentUpload.set(this);
      });

      upload.on('end', function (error, fileObj) {
        if (error) {
          alert('Error during upload: ' + error);
        } else {
          alert('File "' + fileObj.name + '" successfully uploaded');
        }
        template.currentUpload.set(false);
      });

      upload.start();
    }
  }
});

For multiple file upload see this demo code.

Upload base64 string (introduced in v1.7.1):

// As dataURI
Images.insert({
  file: 'data:image/png,base64str…',
  isBase64: true, // <β€” Mandatory
  fileName: 'pic.png' // <β€” Mandatory
});

// As plain base64:
Images.insert({
  file: 'base64str…',
  isBase64: true, // <β€” Mandatory
  fileName: 'pic.png', // <β€” Mandatory
  type: 'image/png' // <β€” Mandatory
});

Stream files

To display files you can use fileURL template helper or .link() method of FileCursor.

Template:

<template name='file'>
  <img src="{{imageFile.link}}" alt="{{imageFile.name}}" />
  <!-- Same as: -->
  <!-- <img src="{{fileURL imageFile}}" alt="{{imageFile.name}}" /> -->
  <hr>
  <video height="auto" controls="controls">
    <source src="{{videoFile.link}}?play=true" type="{{videoFile.type}}" />
    <!-- Same as: -->
    <!-- <source src="{{fileURL videoFile}}?play=true" type="{{videoFile.type}}" /> -->
  </video>
</template>

Shared code:

import { Meteor } from 'meteor/meteor';
import { FilesCollection } from 'meteor/ostrio:files';

const Images = new FilesCollection({collectionName: 'Images'});
const Videos = new FilesCollection({collectionName: 'Videos'});

if (Meteor.isServer) {
  // Upload sample files on server's startup:
  Meteor.startup(() => {
    Images.load('https://raw.githubusercontent.com/VeliovGroup/Meteor-Files/master/logo.png', {
      fileName: 'logo.png'
    });
    Videos.load('http://www.sample-videos.com/video/mp4/240/big_buck_bunny_240p_5mb.mp4', {
      fileName: 'Big-Buck-Bunny.mp4'
    });
  });

  Meteor.publish('files.images.all', function () {
    return Images.find().cursor;
  });

  Meteor.publish('files.videos.all', function () {
    return Videos.find().cursor;
  });
} else {
  // Subscribe to file's collections on Client
  Meteor.subscribe('files.images.all');
  Meteor.subscribe('files.videos.all');
}

Client's code:

Template.file.helpers({
  imageFile() {
    return Images.findOne();
  },
  videoFile() {
    return Videos.findOne();
  }
});

For more expressive example see Streaming demo app

Download button

Template:

<template name='file'>
  <a href="{{file.link}}?download=true" download="{{file.name}}" target="_parent">
    {{file.name}}
  </a>
</template>

Shared code:

import { Meteor } from 'meteor/meteor';
import { FilesCollection } from 'meteor/ostrio:files';
const Images = new FilesCollection({collectionName: 'Images'});

if (Meteor.isServer) {
  // Load sample image into FilesCollection on server's startup:
  Meteor.startup(function () {
    Images.load('https://raw.githubusercontent.com/VeliovGroup/Meteor-Files/master/logo.png', {
      fileName: 'logo.png',
      meta: {}
    });
  });

  Meteor.publish('files.images.all', function () {
    return Images.find().cursor;
  });
} else {
  // Subscribe on the client
  Meteor.subscribe('files.images.all');
}

Client's code:

Template.file.helpers({
  fileRef() {
    return Images.findOne();
  }
});
