Schema

Below is default Files collection schema. Please keep default schema structure when extending it!. To pass your own schema use schema property when passing config to FilesCollection constructor.

For more info see Collection2 and simple-schema packages.

const defaultSchema = {
  _id: {
    type: String
  },
  size: {
    type: Number
  },
  name: {
    type: String
  },
  type: {
    type: String
  },
  path: {
    type: String
  },
  isVideo: {
    type: Boolean
  },
  isAudio: {
    type: Boolean
  },
  isImage: {
    type: Boolean
  },
  isText: {
    type: Boolean
  },
  isJSON: {
    type: Boolean
  },
  isPDF: {
    type: Boolean
  },
  extension: {
    type: String,
    optional: true
  },
  ext: {
    type: String,
    optional: true
  },
  extensionWithDot: {
    type: String,
    optional: true
  },
  mime: {
    type: String,
    optional: true
  },
  'mime-type': {
    type: String,
    optional: true
  },
  _storagePath: {
    type: String
  },
  _downloadRoute: {
    type: String
  },
  _collectionName: {
    type: String
  },
  public: {
    type: Boolean,
    optional: true
  },
  meta: {
    type: Object,
    blackbox: true,
    optional: true
  },
  userId: {
    type: String,
    optional: true
  },
  updatedAt: {
    type: Date,
    optional: true
  },
  versions: {
    type: Object,
    blackbox: true
  }
};

Attach schema (Recommended):

Although this package comes with schema it isn't enabled (attached) by default (since v1.5.0), you're free to use it or not. To attach schema you need to install Collection2 and simple-schema packages separately.

import { FilesCollection } from 'meteor/ostrio:files';
const Images = new FilesCollection({ collectionName: 'Images'});
Images.collection.attachSchema(new SimpleSchema(Images.schema));

Extend default schema:

The default schema is available as a static property of FilesCollection, so you can extend it using a library like underscore:

import { FilesCollection } from 'meteor/ostrio:files';
const mySchema = Object.assign({}, FilesCollection.schema, {
  myProp: {
    type: String
  }
});

const Images = new FilesCollection({
  collectionName: 'Images',
  schema: mySchema
});
Images.collection.attachSchema(new SimpleSchema(mySchema));

Or with ES6 object spread syntax:

import { FilesCollection } from 'meteor/ostrio:files';
const mySchema = {
  ...FilesCollection.schema,
  myProp: {
    type: String
  }
};

const Images = new FilesCollection({
  collectionName: 'Images',
  schema: mySchema
});
Images.collection.attachSchema(new SimpleSchema(mySchema));

Pass your own schema (not recommended):

import { FilesCollection } from 'meteor/ostrio:files';
const mySchema = { /* Your schema here */ };

const Images = new FilesCollection({
  collectionName: 'Images',
  schema: mySchema
});
