last-run

Capture and retrieve the last time a function was run.

Usage

var lastRun = require('last-run');

function myFunc(){}

myFunc();
// capture the run after (or before) calling the function
lastRun.capture(myFunc);

// retrieve the last run time
lastRun(myFunc);
//-> outputs the Date.now() when capture was called

API

Note: this module uses a WeakMap shim, and throws on non-extensible functions on platforms that don’t have a native WeakMap implementation

lastRun(fn, [timeResolution]) => [Timestamp]

Takes a function (fn) and returns a timestamp of the last time the function was captured.

Returns undefined if the function has not been captured.

The timestamp is always given in millisecond but the time resolution can be reduced (rounded down). The use case is to be able to compare a build time to a file time attribute. On node v0.10 or with file system like HFS or FAT, fs.stat time attributes like mtime precision is one second.

Assuming lastRun(fn) returns 1426000001111, lastRun(fn, 1000) returns 1426000001.

The default time resolution is 1000 on node v0.10, 0 on node 0.11+ and iojs. More information at default-resolution and undertaker PR #17.

lastRun.capture(fn, [timestamp])

Takes a function (fn) and captures the current timestamp with Date.now(). If passed the optional timestamp, captures that time instead of Date.now(). The captured timestamp can then be retrieved using the lastRun function.

lastRun.release(fn)

Takes a function (fn) and removes the last run timestamp for it.
