Documentation

How it works?

Three ways:

• Expressions: tmpl('{ value }', data). Returns the result of evaluated expression as a raw object.

• Templates: tmpl('Hi { name } { surname }', data). Returns a string with evaluated expressions.

• Filters: tmpl('{ show: !done, highlight: active }', data). Returns a space separated list of trueish keys (mainly used for setting html classes), e.g. "show highlight".

Template examples

tmpl('{ title || "Untitled" }', data)
tmpl('Results are { results ? "ready" : "loading" }', data)
tmpl('Today is { new Date() }', data)
tmpl('{ message.length > 140 && "Message is too long" }', data)
tmpl('This item got { Math.round(rating) } stars', data)
tmpl('<h1>{ title }</h1>{ body }', data)

Falsy expressions

In templates (as opposed to single expressions) all falsy values except zero (undefined/null/false) will default to empty string:

tmpl('{ undefined } - { false } - { null } - { 0 }', {})
// will return: " - - - 0"

tmpl('{}')                 // undefined
tmpl('{ false }', {})      // false
tmpl('{ null }', {})       // null
tmpl('{ 0 }', {})          // 0

Changes in v2.3

• Brackets can not contain characters in the set [\x00-\x1F<>a-zA-Z0-9'",;\\]
• No comments in expressions, the compiler is the only that strip comments
• Attributes with expressions containing > must be quoted
