Definitions of common LoopBack terms.
- Access control list, a list associated with an object that identifies all the subjects that can access the object and their access rights. See Authentication, authorization, and permissions.
- Application Programming Interface. An interface that allows an application program that is written in a high-level language to use specific data or functions of the operating system or another program.
- The IBM API Connect command-line tool. It provides commands to scaffold LoopBack applications. For more information, see Command-line tools.
- Provides the transport-specific mechanisms to make remote objects (and collections thereof) available over their transport. See Strong remoting.
- A mobile operating system created by Google, most of which is released under the Apache 2.0 and GPLv2 open source licenses.
- API Connect
- IBM product that incorporates StrongLoop and LoopBack technology for creating, running, managing, and securing APIs. See DeveloperWorks > API Connect.
- StrongLoop graphical tool suite for the API lifecycle, including tools for building, profiling and monitoring Node apps. StrongLoop Arc is no longer under active development, and will soon be deprecated.
- boot script
/server/bootdirectory. See Defining boot scripts.
- built-in model
- One of the predefined models that every LoopBack application has by default. See Using built-in models.
- A set of identical Node worker processes all receiving requests on the same port. See also: worker.
- A predefined package that extend a basic LoopBack application. Fundamentally, a component is related code bundled together as a unit to enable LoopBack applications for easy reuse. See LoopBack components.
- See LoopBack connector.
- data source
- A data source connects with specific database or other back-end system using a connector. See Connecting models to data sources.
- See route.
- enterprise connector
- A module that connects to back-end data sources such as Oracle, MySQL, or MongoDB.
- environment variable
- A variable that defines an aspect of the operating environment for a process. For example, environment variables can define the home directory, the command search path, the terminal in use, or the current time zone.
- event loop
- Single-threaded execution process that runs a Node.js application, typically making a series of asynchronous function calls.
- Interactive command-line tool that scaffolds all or part of a LoopBack application. See slc loopback command-line reference.
- A closed source, proprietary mobile operating system for Apple devices.
- LoopBack Definition Language, a form of JSON used to define LoopBack models and other configurations.
- load balancer
- Software or hardware that distributes workload across a set of servers to ensure that servers are not overloaded. The load balancer also directs users to another server if the initial server fails.
- LoopBack connector
- A connector that provides access to a back-end system such as a database, REST API, or other service.
- LoopBack DataSource Juggler
- An object-relational mapping that provides a common set of interfaces for interacting with databases, REST APIs, and other data sources.
- LoopBack model
- A model that consists of application data, validation rules, data access capabilities, and business logic that provides a REST API by default.
- Mobile backend as a service. A computing model that connects mobile applications to cloud computing services and provides features such as user management, push notifications, and integration with social networks through a unified API and SDK.
- middleware function
- A function executed when an HTTP request is made to a specified REST endpoint. Since LoopBack is based on Express, LoopBack middleware is the same as Express middleware. See Defining middleware.
- middleware phase
- A stage in application execution when you can call a middleware function. See Defining middleware.
- See LoopBack model.
- model property
- A value attached to a model; for persisted models, corresponds to a database column or field.
- Node package manager, the command-line tool for installing applications and managing dependencies using the npm registry.
- Pertaining to software that is installed and run on the local computers of a user or organization.
- operation hook
- Code that is triggered by a model’s high-level create, retrieve, update, or delete (CRUD) operations. See Operation hooks.
- Persisted model
- A LoopBack model attached to a persistent data source that automatically gets basic create, read, update, and delete methods.
- The stage in the software lifecycle when an application or API is generally available to its end-users or consumers. Contrast with "development" and "testing". Also referred to as "deployment".
- production host
- A server running a production application.
- See model property.
- push notification
- An alert or message to a mobile app. See Push notifications.
- remote object
- A software architectural style for distributed hypermedia systems like the World Wide Web. The term is also often used to describe any simple interface that uses XML (or YAML, JSON, plain text) over HTTP without an additional messaging layer such as SOAP.
- Part of a URL that identifies a resource. For example, in
- Pertaining to the time period during which a computer program is running.
- Software development kit. A set of tools, APIs, and documentation to assist with the development of software in a specific computer language or for a particular operating environment.
- The StrongLoop command-line tool for development and operations. It provides commands to scaffold LoopBack applications. For more information, see Command-line tools.
- The process by which data consistency is achieved between two endpoints such as a provider application and a mobile application. During this process, at either endpoint, data can be updated, created, or deleted. See Synchronization.
- A Node.js child process.
