Working with multiple blueprint files

This document describes 4 different solutions to work APIs that consist of multiple blueprint files. Every of this solution work with all Apiary.io features but editing. To edit a blueprint you have to do it outside of Apiary as Apiary editor does not support working with multiple files. In other words if you are using one of the solutions below avoid editing the blueprint in Apiary.

1. Hercule

Hercule is a CLI tool written in Node.js – available as an NPM package. It uses markdown referencing and linking syntax to transclude other files into a blueprint file. This solution is universal and would work with any Markdown files not just API Blueprint.

The major benefit – unlike any other solutions here – is also that the references are rendered as HTML links in any Markdown editor so the result is HTML that can be browsed!

How do I round to 2 decimals?

In python, you have floats and decimals that can be rounded. If you care about the accuracy of rounding, use decimal type. If you use floats, you will have issues with accuracy.

All the examples use demical types, except for the original value, which is automatically casted as a float.

To set the context of what we are working with, let's start with an original value.

Original Value
