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.

- Compatible with all front-end frameworks from Blaze to React
- Upload via
HTTP
andDDP
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

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;
});
}

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; // 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
});
For more expressive example see Upload demo app
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:https://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();
}
});

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

meta: {}
});

// Subscribe on the client
Meteor.subscribe('files.images.all');

return Images.findOne();

- Where are files stored by default?: by default if
config.storagePath
isn't passed into Constructor it's equals toassets/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 runmeteor 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 tomup.json
, see MUP usage
- a. On
- 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 bothClient
andServer
. For more details read Cookie's repository FAQ - How to pause/continue upload and get progress/speed/remaining time?: see Object returned from

- 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 to6
is recommended for Safari. This issue should be fixed in Safari 11. Switching tohttp
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
