Remove quotes from boolean when form is submitted
I have a simple form.
It POSTs to the server (node js / express), and has a checkbox with a 'true' value when checked.
<form id="demo_form" action="/submit_demo" method="POST">
<input type="checkbox" id="demo_input" name="demo_input" value=true />
</form>
When I receive the data on the server, my values are wrapped in quotes - eg. "true".
This causes issues when submitting data to my api which strictly accepts booleans as true (no quotes).
I can easily manually remove the quotes from any data before submitting to my api BUT it gets a bit painful when dealing with a lot of fields.
Is there a simple solution to sending a boolean value from a form to a server without it being a string?
Any input much appreciated :)

POST/GET parameters do not have any “type”, the values are always send as strings.

That's not how checkboxes work. If checked, they are in the submitted data as a regular key-value pair, the key being the name. Unchecked, not at all. So, the Boolean is in the presence/absence, never in thevalue.

If a form is POSTed and you did not check a checkbox, it will not be included in the payload. So on the server side it should be easy to identify if something was checked or not.
See this codepen for reference: https://codepen.io/anon/pen/KrowNJ
<form method="POST">
<div>
<input type="text" name="message" placeholder="Enter your message...">
</div>
<div>
<input type="checkbox" id="subscribeNews" name="subscribe">
<label for="subscribeNews">Subscribe to newsletter?</label>
</div>
<div>
<button type="submit">Subscribe</button>
</div>
</form>
Hope this helps!
