Files.com JavaScript SDK

The content included here should be enough to get started, but please visit our Developer Documentation Website for the complete documentation.

Introduction

The Files.com JavaScript SDK provides convenient access to all aspects of Files.com from applications written in JavaScript.

This includes directly working with files and folders as well as performing management tasks such as adding/removing users, onboarding counterparties, retrieving information about automations and more.

The JavaScript SDK uses the Files.com RESTful APIs via the HTTPS protocol (port 443) to securely communicate and transfer files so no firewall changes should be required in order to allow connectivity to Files.com.

JavaScript is a Core Focus at Files.com

This SDK is used internally by several Files.com integrations that we maintain, and we work hard to ensure that it is always up to date and performant.

It is also a very popular choice for Files.com customers looking to integrate with Files.com.

Installation

To install the package, use yarn or npm:

yarn add files.com

or

npm install files.com

Usage

Import and Initialize

import Files from "files.com/lib/Files.js";

require() vs. import

The examples provided in the documentation here use the newer ES6 import syntax. To instead use the older CommonJS module syntax with require(), ensure that .default is included. For example:

const Files = require("files.com/lib/Files.js").default;
const User = require("files.com/lib/models/User.js").default;

// destructure to directly assign a named export
const { LogLevel } = require("files.com/lib/Logger.js").default;

Getting Support

The Files.com Support team provides official support for all of our official Files.com integration tools.

To initiate a support conversation, you can send an Authenticated Support Request or simply send an E-Mail to [e-mail].

Authentication

Authenticate with an API Key

Authenticating with an API key is the recommended authentication method for most scenarios, and is the method used in the examples on this site.

To use the API or SDKs with an API Key, first generate an API key from the web interface or via the API or an SDK.

Note that when using a user-specific API key, if the user is an administrator, you will have full access to the entire API. If the user is not an administrator, you will only be able to access files that user can access, and no access will be granted to site administration functions in the API.

Files.setApiKey('YOUR_API_KEY');

// Alternatively, you can specify the API key on a per-object basis in the second parameter to a model constructor.
const user = new User(params, { apiKey: 'YOUR_API_KEY' });

// You may also specify the API key on a per-request basis in the final parameter to static methods.
await User.find(id, params, { apiKey: 'YOUR_API_KEY' });

Don't forget to replace the placeholder, YOUR_API_KEY, with your actual API key.

Authenticate with a Session

You can also authenticate to the REST API or SDKs by creating a user session using the username and password of an active user. If the user is an administrator, the session will have full access to the entire API. Sessions created from regular user accounts will only be able to access files that user can access, and no access will be granted to site administration functions.

API sessions use the exact same session timeout settings as web interface sessions. When an API session times out, simply create a new session and resume where you left off. This process is not automatically handled by SDKs because we do not want to store password information in memory without your explicit consent.

Logging In

To create a session, the create method is called on the Session object with the user's username and password.

This returns a session object that can be used to authenticate SDK method calls.

const session = await Session.create({ username: 'motor', password: 'vroom' });

Using a Session

Once a session has been created, you can store the session globally, use the session per object, or use the session per request to authenticate SDK operations.

// You may set the returned session ID to be used by default for subsequent requests.
Files.setSessionId(session.id);

// Alternatively, you can specify the session ID on a per-object basis in the second parameter to a model constructor.
const user = new User(params, { session_id: session.id });

// You may also specify the session ID on a per-request basis in the final parameter to static methods.
await User.find(id, params, { session_id: session.id });

Logging Out

User sessions can be ended calling the destroy method on the session object.

await Session.destroy();

Configuration

Configuration Options

Base URL

Setting the base URL for the API is required if your site is configured to disable global acceleration. This can also be set to use a mock server in development or CI.

Files.setBaseUrl("https://MY-SUBDOMAIN.files.com");

Log Level

Supported values:

• LogLevel.NONE
• LogLevel.ERROR
• LogLevel.WARN
• LogLevel.INFO (default)
• LogLevel.DEBUG

import { LogLevel } from 'files.com/lib/Logger.js';

Files.setLogLevel(LogLevel.INFO);

Debugging

Enable debug logging of API requests and/or response headers. Both settings default to false.

Files.configureDebugging({
  debugRequest: true,
  debugResponseHeaders: true,
});

Network Settings

Files.configureNetwork({
  // max retries (default: 3)
  maxNetworkRetries: 3,

  // minimum delay in seconds before retrying (default: 0.5)
  minNetworkRetryDelay: 0.5,

  // max delay in seconds before retrying (default: 1.5)
  maxNetworkRetryDelay: 1.5,

  // network timeout in seconds (default: 30.0)
  networkTimeout: 30.0,

  // auto-fetch all pages when results span multiple pages (default: `true`)
  autoPaginate: true,
});

Sort and Filter

Several of the Files.com API resources have list operations that return multiple instances of the resource. The List operations can be sorted and filtered.

Sorting

To sort the returned data, pass in the sort_by method argument.

Each resource supports a unique set of valid sort fields and can only be sorted by one field at a time.

The argument value is a Javascript object that has a property of the resource field name sort on and a value of either "asc" or "desc" to specify the sort order.

Files.setApiKey('my-key');

// Users, sorted by username in ascending order.
const users = await User.list({
  sort_by: { username: "asc"}
});

users.forEach(user => {
  console.log(user.username);
});

Filtering

Filters apply selection criteria to the underlying query that returns the results. They can be applied individually or combined with other filters, and the resulting data can be sorted by a single field.

Each resource supports a unique set of valid filter fields, filter combinations, and combinations of filters and sort fields.

The passed in argument value is a Javascript object that has a property of the resource field name to filter on and a passed in value to use in the filter comparison.

Filter Types

Filter	Type	Description
filter	Exact	Find resources that have an exact field value match to a passed in value. (i.e., FIELD_VALUE = PASS_IN_VALUE).
filter_prefix	Pattern	Find resources where the specified field is prefixed by the supplied value. This is applicable to values that are strings.
filter_gt	Range	Find resources that have a field value that is greater than the passed in value. (i.e., FIELD_VALUE > PASS_IN_VALUE).
filter_gteq	Range	Find resources that have a field value that is greater than or equal to the passed in value. (i.e., FIELD_VALUE >= PASS_IN_VALUE).
filter_lt	Range	Find resources that have a field value that is less than the passed in value. (i.e., FIELD_VALUE < PASS_IN_VALUE).
filter_lteq	Range	Find resources that have a field value that is less than or equal to the passed in value. (i.e., FIELD_VALUE <= PASS_IN_VALUE).

Files.setApiKey('my-key');

// Users who are not site admins.
const users = await User.list({
  filter: { not_site_admin: true }
});

users.forEach(user => {
  console.log(user.username);
});

Files.setApiKey('my-key');

// Users who haven't logged in since 2024-01-01.
const users = await User.list({
  filter_gteq: { last_login_at: "2024-01-01" }
});

users.forEach(user => {
  console.log(user.username);
});

Files.setApiKey('my-key');

// Users whose usernames start with 'test'.
const users = await User.list({
  filter_prefix: { username: "test" }
});

users.forEach(user => {
  console.log(user.username);
});

Files.setApiKey('my-key');

// Users whose usernames start with 'test' and are not site admins, sorted by last login date.
const users = await User.list({
  filter_prefix: { username: "test" },
  filter: { not_site_admin: true },
  sort_by: { last_login_at: "asc" }
});

users.forEach(user => {
  console.log(user.username);
});

Errors

The Files.com JavaScript SDK will return errors by raising exceptions. There are many exception classes defined in the Files SDK that correspond to specific errors.

The raised exceptions come from two categories:

1. SDK Exceptions - errors that originate within the SDK
2. API Exceptions - errors that occur due to the response from the Files.com API. These errors are grouped into common error types.

There are several types of exceptions within each category. Exception classes indicate different types of errors and are named in a fashion that describe the general premise of the originating error. More details can be found in the exception object message using the message attribute.

Use standard Javascript exception handling to detect and deal with errors. It is generally recommended to catch specific errors first, then catch the general FilesError exception as a catch-all.

import Session from 'files.com/lib/models/Session.js';
import * as FilesErrors from 'files.com/lib/Errors.js';

try {
  const session = await Session.create({ username: 'USERNAME', password: 'BADPASSWORD' });
} catch(err) {
  if (err instanceof FilesErrors.NotAuthenticatedError) {
    console.error(`Authorization Error Occurred (${err.constructor.name}): ${err.error}`);
  } else if (err instanceof FilesErrors.FilesError) {
    console.error(`Unknown Error Occurred (${err.constructor.name}): ${err.error}`);
  } else {
    throw err;
  }
}

Error Types

SDK Errors

SDK errors are general errors that occur within the SDK code. These errors generate exceptions. Each of these exception classes inherit from a standard FilesError base class.

import * as FilesErrors from 'files.com/lib/Errors.js'

FilesErrors.ConfigurationError ->
FilesErrors.FilesError ->
Error

SDK Exception Classes

Exception Class Name	Description
ConfigurationError	Invalid SDK configuration parameters
EmptyPropertyError	Missing a required property
InvalidParameterError	A passed in parameter is invalid
MissingParameterError	A method parameter is missing
NotImplementedError	The called method has not be implemented by the SDK

API Errors

API errors are errors returned by the Files.com API. Each exception class inherits from an error group base class. The error group base class indicates a particular type of error.

import * as FilesErrors from 'files.com/lib/Errors.js'

FilesErrors.NotAuthorized_FolderAdminPermissionRequiredError ->
FilesErrors.NotAuthorizedError ->
FilesErrors.FilesApiError  ->
FilesErrors.FilesError  ->

Case Sensitivity

The Files.com API compares files and paths in a case-insensitive manner. For related documentation see Case Sensitivity Documentation.

The pathNormalizer.same function in the Files.com SDK is designed to help you determine if two paths on your native file system would be considered the same on Files.com. This is particularly important when handling errors related to duplicate file names and when developing tools for folder synchronization.

import { pathNormalizer } from 'files.com/lib/utils.js';

if (pathNormalizer.same('Fïłèńämê.Txt', 'filename.txt')) {
  // the paths are the same
}

Mock Server

Files.com publishes a Files.com API server, which is useful for testing your use of the Files.com SDKs and other direct integrations against the Files.com API in an integration test environment.

It is a Ruby app that operates as a minimal server for the purpose of testing basic network operations and JSON encoding for your SDK or API client. It does not maintain state and it does not deeply inspect your submissions for correctness.

Eventually we will add more features intended for integration testing, such as the ability to intentionally provoke errors.

Download the server as a Docker image via Docker Hub.

The Source Code is also available on GitHub.

A README is available on the GitHub link.
