About

This module installs the Mustache flow-node to be used within Axway API Builder's flow editor.

The Mustache flow-node allows the evaluation of Mustache templates using values from the flow.

Format string

The Format string method evaluates the template given with the data supplied. This allows complex values to be constructed from values that exist in the flow's context.

ParamTypeRequiredDescription
dataobjectyThe data to evaluate the template with. Use $ to access the entire context.
templatestringyThe template being evaluated.

Format object

The Format object method is similar to the Format string method. It evaluates the template given with the data supplied. However the resulting string value is then JSON parsed. This allows the creation of JavaScript values and objects from the evaluated template.

ParamTypeRequiredDescription
dataobjectyThe data to evaluate the template with. Use $ to access the entire context.
templatestringyThe doT template being evaluated.

Mustache Templates

The Javascript implementation of Mustache being used is https://github.com/janl/mustache.js.

Example

In the examples the Flow is going to be attached to an API that has three parameters, firstname, lastname and gender.

Basic interpolation {{ }}

The template can be used to quickly concatenate values.

Requesthttp://localhost:8080/api/example?firstname=Clark&lastname=Kent&gender=m
data$.params
template{{firstname}} {{lastname}}
OutputClark Kent
Conditionals {{^value}}{{/value}}

The template evaluation supports boolean checkes to tailor the output based on the input.

Requesthttp://localhost:8080/api/example?firstname=Clark&lastname=Kent&male=true
data$
templateHello {{#male}}Mr{{/male}}{{^male}}Ms{{/male}} {{surname}}
OutputHello Mr Kent
Requesthttp://localhost:8080/api/example?firstname=Lois&lastname=Lane
data$.params
templateHello {{#male}}Mr{{/male}}{{^male}}Ms{{/male}} {{surname}}
OutputHello Ms Lane
Array Iteration {{# }}

The template engine can also iterate over arrays, creating content for each element in the array.

Requesthttp://localhost:8080/api/example?names=Tom,Dick,Harry
data$.params
template{{#names}}{{.}} {{/names}}
OutputTom Dick Harry
