Jan 05, 2017 Generating Random Numbers in Node-RED This is to simulate temperature readings using Node-RED. Kiran Shashi Published on January 5, 2017 / Updated on January 5, 2017. Make some modifications to generate random numbers. This should generate the random numbers and you should see that in the debug console on the right of the Node-RED. There are several other solutions to generate unique identifiers. Some of them may be good for distributed environments; some others may work only on a single node. In this post, I wanted to share with you some simple solutions producing unique identifiers in distributed environments which could be implemented in Node.js in production systems. Random String Generator. This form allows you to generate random text strings. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. Generating random strings in Node.js or JavaScript is useful in various situations. For example, when generating an application or encryption key you want to create random strings with a minimal chance of duplication or collision. This tutorial shows you two ways to create a random string with JavaScript. Node.js Series Overview. This article describes how to generate a random number using JavaScript. Method 1: Using Math.random function: The Math.random function is used to return a floating-point pseudo-random number between range 0,1), 0 (inclusive) and 1 (exclusive). This random number can then be scaled according to the desired range. The Math.random function returns a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range. The implementation selects the initial seed to the random number generation algorithm; it cannot be chosen or reset by the user.
generate([len], [keys])
Generate cryptographically strong pseudo-random string, with given length.
- len: the length of the generated string, default is 16
- keys: optional keys, default is base62, including: 0-9, a-z, A-Z
generateDigits([len])
Generate random digits, with given length. optional keys: 0-9
- len: the length of the generated string, default is 16

generateBase30([len])
Generate random string that is easy to read by human, with given length.
optional keys: 1-9, A-Z exclude(E, G, I, J, O) for human read
- len: the length of the generated string, default is 16
