Readme
exception-formatter
is an NPM package that takes exceptions or stack traces that would normally look like this:
and makes them look like this:
or, in HTML, like this:
npm install --save exception-formatter
exceptionFormatter = require('exception-formatter');
console.log( exceptionFormatter(err, options) );
Where err
is either an Error
, a {stack}
object, or a string containing a stack trace.
options
is an optional parameter containing the following:
options.format
- one of 'ascii', 'ansi', 'html'. 'ascii' and 'ansi' are identical, except
that 'ansi' will use ANSI color codes to highlight lines.options.maxLines
- The maximum number of lines to print from the exception. 0 or null
for
unlimited (the default.) "auto"
to truncate after the last line in your source code.options.basepath
- this is your project's root folder. If you're writing code in
src/myFile.js, then this should be path.resolve(__dirname, '..')
. This path will be
stripped from the start of every filename in the exception, and is also used to help
decide which code is "your code" and which is not. If this is not provided, then process.cwd()
is used by default.options.basepathReplacement
- String used to replace the basepath
. Defaults to "./".options.colors
- (Only for format = 'ansi'
) If true (the default) then lines which are
"your code" will be bolded and colorized. If false, then lines will only be bolded.options.inlineStyle
- (Only for format = 'html'
) If this option is true, then each line will
be styled with inline style
attributes. If false, each line will be given a class
instead
and you can do your own styling. Note that inline styline is usually required if you want to
email an exception, since email clients will generally ignore style sheets.exception-formatter
will mark code as "your code" if it is in options.basepath
, and if it does
not contain node_modules
anywhere in it's path.
