Bump packages :P or (basically) anything!


  • Ridiculously customizable, yet easy to use
  • Sane default configuration (bumps package.json-like files)
  • Supports both synchronous operations and promise-based async
  • No (zero, zip, zilch) hard dependencies


  • npm install bump-anything
  • (optional) install default dependencies if not customizing:
    • npm install semver when

Simple Example

The default configure method will return a "bumper" with the following expectations:

  • The locator points to a readable JSON file
  • The JSON document contains a "version" property at the root of the document

This works just fine with a standard "package.json" file.

var bumper = require("bump-anything").configure(),
	log = console.log,
	err = console.err;

bumper.major("package.json").then(log, err); // or 'minor' or 'patch'

// > { oldVersion: "1.1.1", newVersion: "2.0.0" }


To create a configured "bumper", you pass options to the configure method that will override the default configuration.

var myBumper = require("bump-anything").configure(options);

To create a "bumper" with the default configuration, omit the options, or pass undefined or null.

var bumper = require("bump-anything").configure();

Configuration options

Any of the following options can be overriden. Take care to match the interface of the default methods.

readContent({string} locator) => {string} content

Returns the content from the location specified by locator.

By default, uses fs.readFileSync with encoding set to "utf8".

writeContent({string} locator, {string} content) => void

Write content to the location specified by locator.

By default, uses fs.writeFileSync with encoding set to "utf8".

getVersion({string} content) => {string} version

Return the version found in content.

By default, parses content as JSON and returns the top-level version property.

setVersion({string} content, {string} version) => {string} newContent

Return content, modified to reflect the new version.

By default, parses content as JSON and updates the top-level version property, then returns "pretty" JSON stringified with 2 spaces.

increment({string} version, {string} type) => {string} newVersion

Increment version using semantic type type, returning newVersion.

By default, uses npm's own semver package inc method.

pipeline({array} methods, [{string} args...]) => {promise}

Returns a promise by "piping" each method's result to the next.

By default, uses cujojs's when library's pipeline implementation.


.configure([{configuration} options]) => Bumper

Create a "bumper" with the given configuration options. If options are omitted, sane defaults will be used.

Bumper#bump({string} locator, {string} type) => Promise

Bump the resource specified by locator with the given version type. The type must be one of: "major", "minor", or "patch".

The promise resolves with the following object:

  • locator: The locator specified in the call
  • type: The type specified in the call
  • oldVersion: The original version found in content
  • newVersion: The incremented version

Bumper#major({string} locator) => Promise

Convenience method, calls bump with type set to "major".

Bumper#minor({string} locator) => Promise

Convenience method, calls bump with type set to "minor".

Bumper#patch({string} locator) => Promise

Convenience method, calls bump with type set to "patch".


Here are just a few examples of how to configure bump-anything for various tasks:

Change the location when writing

function writeContent(locator, content) {
  fs.writeFileSync(locator + ".new", content);

var bumper = require("bump-anything").configure({ writeContent: writeContent });
bumper.bump("package.json").done(); // bumps to "package.json.new"

Write pretty JSON with custom spacing

function setVersion(content, version) {
	var data = JSON.parse(content),
		indent = 5;

	data.version = version;
	return JSON.stringify(data, null, indent);

A unique JSON file format

function getVersion(content) {
  return JSON.parse(content).version.current;
function setVersion(content, version) {
  var data = JSON.parse(content);
  content.version.current = version;
  return content;

var bumper = require("bump-anything").configure({ getVersion: getVersion, setVersion: setVersion });
