Tripetto-block-calculator NPM

Tripetto is a full-fledged form kit. Rapidly build and run smart flowing forms and surveys. Drop the kit in your codebase and use all of it or just the parts you need. The visual builder is for form building, and the runners are for running those forms in different UI variants. It is entirely extendible and customizable. Anyone can build their own building blocks (e.g., question types) or runner UI's.

Calculator block

Calculator block for Tripetto. This block can perform all sorts of calculations (see a list of supported operations below). It is a headless block, so it doesn't require a UI implementation for the runner.

Recall value	Supplies the value of another question block (for example from a number block, rating block or scale block) to the calculator.
Subcalculation	Performs a (sub) calculation for multistep formulas and supplies the result to the calculator.

Get started

You need to install or import this block to use it in Tripetto. If you are using the CLI version of the builder, you can find instructions here. If you are embedding the builder into your own project using the library, take a look here.

Use cases

Directly in your browser (add <script src="https://unpkg.com/tripetto-block-calculator"></script> to your HTML);
In the CLI builder (install the block using npm i tripetto-block-calculator -g and update your Tripetto config);
In your builder implementation (just add import "tripetto-block-calculator"; to your code);
In your runner implementation (simply add import "tripetto-block-calculator/runner"; to your code.
