Files for Meteor.js

Stable, fast, robust, and well-maintained Meteor.js package for files management using MongoDB Collection API. What does exactly this means? Calling .insert() method would initiate a file upload and then insert new record into collection. Calling .remove() method would erase stored file and record from MongoDB Collection. And so on, no need to learn new APIs. It's flavored with extra low-level methods like .unlink() and .write() for complex integrations.

ToC:

Key features

Installation:

Install ostrio:files from Atmosphere

meteor add ostrio:files

ES6 Import:

Import in isomorphic location (e.g. on server and client)

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

API overview

For detailed docs, examples, and API β€” read documentation section.

  • FilesCollection Constructor [Isomorphic] - Initialize FilesCollection
  • insert() [Client] - Upload file(s) from client to server
  • find() [Isomorphic] - Create cursor for FilesCollection
  • remove() [Isomorphic] - Remove files from FilesCollection and "unlink" (e.g. remove) from FS
  • findOne() [Isomorphic] - Find one file in FilesCollection
  • write() [Server] - Write Buffer to FS and FilesCollection
  • load() [Server] - Write file to FS and FilesCollection from remote URL
  • addFile() [Server] - Add local file to FilesCollection from FS
  • unlink() [Server] - "Unlink" (e.g. remove) file from FS
  • link() [Isomorphic] - Generate downloadable link

new FilesCollection([config]) [Isomorphic]

Shared code:

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

const imagesCollection = 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 imagesCollection.find().cursor;
  });
}

insert(settings[, autoStart]) [Client]

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 imagesCollection = new FilesCollection({collectionName: 'images'});
export default imagesCollection; // import 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 = imagesCollection.insert({
        file: e.currentTarget.files[0],
        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
imagesCollection.insert({
  file: 'data:image/png,base64str…',
  isBase64: true, // <β€” Mandatory
  fileName: 'pic.png' // <β€” Mandatory
});

// As plain base64:
imagesCollection.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 imagesCollection = new FilesCollection({collectionName: 'images'});
const videosCollection = new FilesCollection({collectionName: 'videos'});

if (Meteor.isServer) {
  // Upload sample files on server's startup:
  Meteor.startup(() => {
    imagesCollection.load('https://raw.githubusercontent.com/veliovgroup/Meteor-Files/master/logo.png', {
      fileName: 'logo.png'
    });
    videosCollection.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 imagesCollection.find().cursor;
  });

  Meteor.publish('files.videos.all', function () {
    return videosCollection.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 imagesCollection.findOne();
  },
  videoFile() {
    return videosCollection.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 imagesCollection = new FilesCollection({collectionName: 'images'});

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

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

Client's code:

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

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 chunk size is reduced by algorithm, due to error thrown if 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
