This is a package that shortens strings like Finder on Mac does. Instead of trimming from the start or end it trims the string in the middle and adds a filler char.

For example:

This is a long string that will be trimmed

Will become:

This is ...trimmed

You call the functionality with the trimMiddle method, which takes three parameters:

• str - the string to split (mandatory).
• length - an integer, preset to 16 (optional).
• replaceString - string to add in the middle, preset to ... (optional)

For example:

trimMiddle('This is a long string that will be trimmed', 8, ↔')

results in:

This↔med

The method splits sentences with emoji, unlike a substring() solution would. You can try it using the demo page or demo.js on the commmand line.

Use it via npm:

npm -i trimmiddle

Or the client-side package via unpkg

<script src="https://unpkg.com/trimmiddle@0.2.0/clientside.js"></script>
