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.

Why `Meteor-Files`?

Compatible with all front-end frameworks from Blaze to React
Upload via HTTP and DDP transports, read about difference
Sustainable and resumable uploads, which will survive connection interruption and server reboot (if a server has persistent storage)
Upload files through computing cloud without persistent File System, like Heroku
You need store files at GridFS, AWS S3, Google Storage or DropBox? (Use 3rd-party storage)
You need to check file mime-type, size or extension? Easy! Use onBeforeUpload hook
You need to resize images after upload? Easy too! Use onAfterUpload hook, and manage file's subversions in a single record

Installation:

meteor add ostrio:files

ES6 Import:

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

API overview (full API)

`new FilesCollection([config])` [Isomorphic]

Read full docs for FilesCollection Constructor

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]

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; // 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 = Images.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
Images.insert({
  file: 'data:image/png,base64str…',
  isBase64: true, // <— Mandatory
  fileName: 'pic.png' // <— Mandatory
});

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

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();
  }
});

FAQ:

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
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 — enable withCredentials; enable {allowQueryStringCookies: true} and {allowedOrigins: true} on both Client and Server. For more details read Cookie's repository FAQ
How to pause/continue upload and get progress/speed/remaining time?: see Object returned from insert method
When using any of accounts packages - package accounts-base must be explicitly added to .meteor/packages above ostrio:files
cURL/POST uploads - Take a look on POST-Example by @noris666
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
Make sure you're using single domain for the Meteor app, and the same domain for hosting Meteor-Files endpoints, see #737 for details
When proxying requests to Meteor-Files endpoint make sure protocol http/1.1 is used, see #742 for details
