An expression describes a calculation, a formula gives that calculation a name and uses it as a recipe. As mass or acceleration changes, force automatically updates to a new value. One writes force = mass * acceleration as a formula, in the mathematical sense, for calculating force that is always true. In Power Fx, instead of only writing an expression that has no specific meaning, one writes a formula that binds the expression to an identifier. It is up to the maker to place it in a variable or pass it to a function. An expression by itself says nothing about what it is calculating. The result of an expression can be placed in a variable, used as an argument to a procedure, or nested in a bigger expression. For example, mass * acceleration in most languages expresses multiplication of mass and acceleration.
By breaking Power Fx out of Power Apps, we are going to answer these questions for building automation, or a virtual agent, or other domains.Īll programming languages, including Power Fx, have expressions: a way to represent a calculation over numbers, strings, and other data types. Let’s bring app creation to them that is easy and leverages Excel concepts that they already know. Hundreds of millions of people create spreadsheets with Excel every day. These were the questions that inspired the creation of Power Apps and Power Fx. What if you could leverage your existing spreadsheet knowledge? What if you could build an app as easily as you build a spreadsheet? To learn more about Power Fx, see the following articles: This article is an overview of the language and its design principles. We are in the process of extracting it from Power Apps and using it in other Power Platform products and as an open-source. It is currently integrated into canvas apps where you can experience it today. Power Fx will be made available as an open-source. The same expression language is used for both declarative and imperative logic. Spreadsheets don't typically have buttons that can submit changes to a database, but apps often do. The formula logic recalculates automatically similar to how a spreadsheet does which affects the control's visibility.Īlso, Power Fx offers imperative logic when needed. For example, think of a UI control's Visible property as a spreadsheet cell, with an associated formula that calculates its value based on other control's properties. Power Fx binds objects together with declarative spreadsheet-like formulas.

It enables the full spectrum of development from "no-code" for those who have never programmed before to "pro code" for the seasoned professional, with no learning or rewriting cliffs in between, enabling diverse teams to collaborate and save time and expense. The "low" is due to the concise and simple nature of the language, making common programming tasks easy for both makers and developers.

It is a low-code language that makers can work with directly in an Excel-like formula bar or Visual Studio Code text window. Power Fx is expressed in a human-friendly text. It is a general-purpose, strong typed, declarative, and functional programming language. Microsoft Power Fx is the low-code language that will be used across the Microsoft Power Platform.

This overview article and the associated articles are a work in progress as we extract the language from canvas apps, integrate it with other products of the Power Platform, and make it available as open source.
