What can developer do with Linx

Linx allows users to set up interactions with databases, files, web services, email and other APIs to efficiently perform repetitive tasks and automate backend workflows

Users create solutions in the Linx Designer, a drag-and-drop desktop IDE. Solutions are designed to include server-side business logic, such as data validation, workflow rules, calculations, and more, with unlimited flexibility.

Completed solutions (applications) are deployed to the Linx Server where automated events are executed based on your predetermined triggers.

Use cases

  1. Host web services or APIs.
  2. Integrate systems.
  3. Automated processing.
  4. Back-end for mobile apps.

Some common use cases of Linx are: Integration layer: Consume and host web services, process custom files locally and via FTP, multiple database drivers. Automation: Perform automatic file transfers and imports, directory monitoring, script executions, API updates, batch file processing etc. APIs: Build, extend and host REST & SOAP web services.

Application units

  1. Linx Designer ( like Visual Studio, with drag and drop, without code.)
  2. Plugins for common operations on databases, files, web services, APIs etc. (like nuget or npm packages. They provide pre-built functionality.)
  3. Linx Server: Server application to host one or more solutions.(like a .Net Application Server with built-in monitoring, configuration)

11. graphql.org

logo graphql.org


A query language for your API β€” GraphQL provides a complete description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

πŸ›  graphql.org's Features

What can developer do with graphql.org

Ask for what you need, get exactly that

Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server.

Get many resources in a single request

GraphQL queries access not just the properties of one resource but also smoothly follow references between them. While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request. Apps using GraphQL can be quick even on slow mobile network connections.

Describe what’s possible with a type system

GraphQL APIs are organized in terms of types and fields, not endpoints. Access the full capabilities of your data from a single endpoint. GraphQL uses types to ensure Apps only ask for what’s possible and provide clear and helpful errors. Apps can use types to avoid writing manual parsing code.
