• Framework for frontend web development • Ideal for building single-page applications • Best suited for projects that target modern browsers • Open source, under BSD license What is MontageJS?

Serialization • Instantiate components • Attach components to the page DOM • Populate component properties — static values or bindings

FRB Bindings • Propagate changes between object properties • Can be 1-way or 2-way • Bind to other components or regular JS objects

Serialization "number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } } HTML MJS

Serialization "number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } } HTML MJS Prototype: path to the desired component

Serialization "number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } } HTML MJS Element: Montage ID of DOM element

"number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } }, "slider": { "prototype": "digit/ui/slider.reel", "properties": { "element": {"#": "slider"} }, "bindings": { "value": {"<->": "@number.value"} } } Adding a 2nd component HTML MJS

"number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } }, "slider": { "prototype": "digit/ui/slider.reel", "properties": { "element": {"#": "slider"} }, "bindings": { "value": {"<->": "@number.value"} } } HTML MJS <-> signifies a 2-way binding

"number": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "number"} } }, "slider": { "prototype": "digit/ui/slider.reel", "properties": { "element": {"#": "slider"} }, "bindings": { "value": {"<->": "@number.value"} } } HTML MJS @ references an existing component

"celsiusNumber": { "prototype": "digit/ui/number-field.reel", "properties": { "element": {"#": "celsius"} }, "bindings": { "value": {"<->": "(+@number.value - 32) / 1.8"} } } MJS Complex FRB Expressions

! "sorted": {"<-": “numbers.sorted{}”} ! "evens": {"<-": “numbers.filter{!(%2)}”} ! "low": {"<-": “numbers.filter{this <= ^maxNumber}”} ! "allChecked": {"<-": “options.every{checked}”} ! "payroll": {"<-": “departments.map{employees.sum{salary}}.sum()”} ! "index": {"<-": “folks.group{id}.sorted{.0}.map{.1.last()}”} MJS Fun with FRB

• Command line tool that optimizes apps for production deployment • Consolidates code into bundles to reduce number of requests • Minifies code to reduce total download size MontageJS Optimizer
