About

Fusio is an open source API management platform which helps to create innovative API solutions.

Use-Cases

• API-Product
  Fusio helps you to create a great API product, besides building an API it provides a developer portal where developers
  can register and a way to monetize your API
• API-Gateway
  Fusio can be used as gateway to your internal API and microservices. It handles all common features like
  Authorization, Rate-Limiting and Schema-Validation
• SPA-Backend
  Fusio can be used as backend to build SPAs using popular Javascript-Frameworks like i.e. Angular, React or Vue. It
  provides a powerful code generator which can automatically generate an SDK for your API
• Low-Code-Platform
  Fusio allows you to build API endpoints without coding knowledge. I.e. it provides an Entity generator which you can
  use to easily create complete CRUD APIs.
• API-Framework
  For more complex use cases you can use Fusio also as framework to build complete APIs from scratch. This means you
  build custom actions where you can use the wide PHP ecosystem to solve your task.

Features

Fusio helps you to build APIs providing out-of-the-box enterprise features so that you can concentrate on your business
case. Please take a look at our documentation website
for more information. The following feature list gives you a first overview:

• OpenAPI generation
  Fusio generates automatically an OpenAPI specification for the defined routes
• SDK generation
  Fusio can automatically generate a client SDK for your API based on the defined schema
• Webhook support
  Fusio contains a webhook system which helps to build publish/subscribe for your API
• Rate limiting
  Fusio provides a way to rate limit requests based on the user or app
• Authorization
  Fusio uses OAuth2 for API authorization
• Monetization
  Fusio provides a simple payment system to charge for specific routes
• Validation
  Fusio uses the TypeSchema to automatically validate incoming request data
• Analytics
  Fusio monitors all API activities and shows them on a dashboard
• User management
  Fusio provides a developer app where new users can login or register a new account through GitHub, Google, Facebook or
  through normal email registration

Apps

Fusio provides many apps which help to work with the API. Mostly apps are
simple JS apps, which work with the internal API of Fusio. You can see a list of all available apps at our
marketplace. You can install such an app either through a CLI command i.e.
php bin/fusio marketplace:install fusio or through the backend app.

All apps are installed to the apps/ folder. You need to tell Fusio the public url to the apps folder at the .env
file by defining the APP_APPS_URL variable. Depending on your setup this can be either a custom sub-domain like
https://apps.acme.com or simply the sub folder https://acme.com/apps.

Backend

The backend app is the main app to configure and manage your API. The installer automatically installs this app. The app
is located at /apps/fusio/.

VSCode

Fusio provides a VSCode extension
which can be used to simplify action development. This means you can develop every action directly inside
the VSCode editor.

SDK

To build and integrate apps with Fusio we provide several SDKs which you can use to work with a Fusio instance or you
can also simply manually talk to the REST API.

Ecosystem

Fusio is an open source project which you can use freely for private and commercial projects under the terms of the
Apache 2.0 license. Besides our core product we offer additional services to augment the functionality of Fusio.

• SDKgen
  SDKgen is a powerful code generator to automatically build client SDKs for your REST API.
• APIgen
  Generate fully working and customizable APIs based on your data model.
• APImon
  APImon provides an intuitive service to monitor and analyze API endpoints.
• TypeSchema
  A JSON format to describe data models in a language neutral format.
• TypeAPI
  An OpenAPI alternative to describe REST APIs for type-safe code generation.
• TypeHub
  A collaborative platform to design and build API models and client SDKs.
• PSX
  An innovative PHP framework dedicated to build fully typed REST APIs.

Installation

It is possible to install Fusio either through composer or manually file download.

Composer

composer create-project fusio/fusio

Download

https://github.com/apioo/fusio/releases

Configuration

You can either manually install Fusio with the steps below or you can also use the browser based installer at
public/install.php. Note because of security reasons it is highly recommended removing the installer script after the
installation.

• Adjust the configuration file
  Open the file .env in the Fusio directory and change the APP_URL to the domain pointing to the public folder.
  Also insert the database credentials to the APP_CONNECTION keys. Optional adjust APP_APPS_URL to the public url
  of the apps folder (in case you want to use apps).
• Execute the installation command
  The installation script inserts the Fusio database schema into the provided database. It can be executed with the
  following command php bin/fusio migrate.
• Create administrator user
  After the installation is complete you have to create a new administrator account. Therefor you can use the following
  command php bin/fusio adduser. Choose as account type “Administrator”.
• Install backend app
  To manage your API through an admin panel you need to install the backend app. The app can be installed with the
  following command php bin/fusio marketplace:install fusio

You can verify the installation by visiting the APP_URL with a browser. You should see an API response that the
installation was successful.

In case you want to install Fusio on a specific database you need to adjust the APP_CONNECTION parameter. You can
use the following connection strings:

• MySQL: pdo-mysql://root:test1234@localhost/fusio
• PostgreSQL: pdo-pgsql://postgres:postgres@localhost/fusio
• SQLite: pdo-sqlite:///fusio.sqlite

In general it is possible to install Fusio on all database which are supported
by our database abstraction layer but our internal test cases are only covering MySQL, PostgreSQL and SQLite so there is
no guarantee that everything works.

Docker

It is possible to setup Fusio through docker. This has the advantage that you automatically get a complete running Fusio
system without configuration. This is especially great for testing and evaluation. To setup the container you have to
checkout the repository and run the following command:

docker-compose up -d

This builds the Fusio system with a predefined backend account. The credentials are taken from the env variables
FUSIO_BACKEND_USER, FUSIO_BACKEND_EMAIL and FUSIO_BACKEND_PW in the docker-compose.yml. If you are planing to
run the container on the internet you must change these credentials.

Domains

By default the complete Fusio project can be hosted on a single domain. In this setup your API is served at the root
directory and the developer portal and backend apps are directly served from the /apps folder. This setup is easy to use
since it requires no configuration. If you want to run Fusio in a production environment we recommend to create the
following sub-domain structure:

• api.acme.com
  Contains only Fusio where your API is served, in this case you can delete the apps/ folder from the public/ folder
• developer.acme.com
  Contains the developer portal app where external developers can register
• fusio.acme.com
  Optional the backend app where you can manage your Fusio instance. You can host this also on a complete separate
  internal domain, the backend app only needs access to the Fusio API.

This is of course only a suggestion and you are free to choose the domain names how you like.
