Smiley Library
A collection of useful Node.js functions and utilities.
These are functions I use often but are too simple to have their own package.
Functions
zeroPad(string, totalLength) -> String
Zero pad the given number into a string with the given total length.
hexDump(Buffer) -> String
Render the bytes of the given Buffer to a hex-editor-like format.
isUUID(string) -> Boolean
Uses a Regex to test the given string for the UUID format.
iecToDecimal(string) -> Number
Converts an IEC size (e.g. 4.0K) to a full decimal Number (e.g. 4096)
titleCase(string) -> String
Converts a string to Title Case. Hyphens and underscores are converted to spaces.
getNetworkInterfaces() -> Array
Get an array of network interfaces in a different format than the typical os.networkInterfaces(). Makes traversing the interfaces easier.
getExternalIPAddress() -> String
Return an IP address marked as external in os.networkInterfaces(). No guarantees about internet access.
findModuleRoot(moduleName) -> String
Find the root of the given module defined as the first directory above the module's entry point with a package.json file.
debounce(function, waitMS, runImmediate) -> function
Debounce the given function by preventing multiple executions within the given waitMS time. If runImmediate is true, the function will be executed immediately the first time.
