Advanced tools
brunch-preval v0.0.3
Simple JS based preprocessing for Brunch static HTML files.
Install
$ npm i brunch-preval
Use
Simply open a static HTML file and put some javascript inside {{ double curly braces }}. The javascript will be evaluated, and the results will be interpolated in its place.
<html><body>{{ Math.random() }}</body></html>
Escaping
Use the backslash (\) character to escape a replacement
<html><body>\{{ This won't be processed. }}</body></html>
Escaping Escapes
Backslashes may also be used to escape a backslash.
<html>
<body>
{{ "This WILL be processed." }}
\{{ "This won't be processed."" }}
\\{{ "This WILL be processed and will be preceeded by a single backslash." }}
\\\{{ "This won't be processed and will be preceeded by a single backslash." }}
\\\\{{ "This WILL be processed and will be preceeded by a 2 backslashes." }}
</body>
</html>
Alt Notation
<<< triple angle brackets >>> or ((( triple parens ))) may also be used.
Configure

Include/exclude
You can more finely control which HTML files are processed by specifying a regex for the include & exclude keys.
If a file matches both include and exclude the include will take precedence.
exports.plugins = {
preval:{
exclude: /thing.html$/,
, include: /something.html$/,
}
};
Tokens
Tokens can be specified in your Brunch config.
Tokens may be static values or the results of a function. Dynamic tokens will be generated once per compile pass, and will have the same value for all files processed in each pass.
Tokens in templates can be accessed on the _ object.
<html><body>{{ _.BUILD_TIME }}</body></html>
exports.plugins = {
preval:{
tokens: {
STATIC_VAL: 'Some value',
BUILD_TIME: ()=>(new Date).getTime() / 1000,
}
}
};
Suppress Logging
Set log to false in your Brunch config to stop BrunchPreval from logging to the console during compilation.
exports.plugins = {
preval:{
log: false
}
};
