The Libmon Library handles token validation and usage limits for a library.

It is open-source.

Unfortunately, the library does not work without make a call to the internet.

Set-Up

npm install libmon --save

const { Libmon } = require("libmon")
Libmon.intialize("my-calculator-package")

Libmon exposes a few methods such as crash() and increment() to create internal counters that limit the amount of usage on a library without updgrading to a token.

If a token is valid, Libmon methods will not crash a program.

Usage

The libmon library should not be exposed to the end user. It's used internally by your library, and users should pass in a token.

class MyCalculatorLibrary(){
    constructor(token){
        Libmon.intialize("my-calculator-package")

        // check if the token is valid. Makes internet call
        Libmon.validate(token);

        // create counter with a max of 10 calls
        Libmon.setupCounter("number-of-prime-calls", 10)
    }

    function myPaidMethod() {
        // artificially crash the program if token is invalid
        Libmon.disable();
        return "hello world"
    }

    function getPrimeNumber() {
        // increment the counter
        // throw an error if called > 10 times
        Libmon.increment("number-of-prime-calls")
        return 3
    }


}

Tolerance

Our intention is to make programs a little more inconvenient without a valid token rather than create strict payment models.

The consumer of a library and purchaser of a token always has benefit of the doubt.

• If there is no internet, validation will always pass.
• If the libmon server is down, validation will always pass

Generating Tokens

You can use our token generation service. To publish to Libmon, and get free tokens, simply purchase here. It costs $20 for 100 tokens.

We can help you setup a payment portal so you can charge for access to your library.
