NPM version


Multimeter is a hackable console for the game Screeps. It lets you access your Screeps console without loading up the full website (and as a result lets you play Screeps for much longer on a single battery charge), and is hackable with plugins.

screenshot of main interface


  • Terminal (command line) program, no browser or GUI required.
  • Send console commands from the program.
  • Rich console output formatting.
  • Add plugins to get new functionality.


npm install -g screeps-multimeter

When you run multimeter for the first time, it will ask a few setup questions to get you connected. These settings will be saved to a config file in the current directory.

Connecting to the official server

Simply enter your Screeps API token. You will also need to specify the name of the shard to use.

Connecting to a private server

Leaving the api token blank and hitting enter will allow you to connect to a private server. You will need to provide the hostname, the port, and your username and password. Your username can either be your username or your email. You can get a password by setting up screepsmod-auth.

The main interface has a command line on the bottom. In type /help to see a list of the available commands. Type /quit to exit the program.

Colors and Formatting

Console coloring and formatting is made possible by blessed's tags. Some of the tags you can use are:

  • {color-fg} - Change the foreground color.
  • {color-bg} - Change the background color.
  • {bold}, {underline}, {blink}, {inverse}, {invisible} - Apply the character style.
  • {/style} - Stop using the given style, e.g. {/bold}.
  • {/} - Reset to normal characters.
  • {|} - Align the rest of the line to the right.

Colors can be specified as a name, e.g. red, blue, yellow, cyan (see colorNames from blessed for a complete list), or as a hex code, e.g. #ffff00.


Multimeter currently ships with these plugins enabled by default. To select which plugins are loaded, edit the plugins array in your screeps-multimeter.json.

Plugin: Alias

The alias plugin can be used to easily store and access commonly used console commands. Create a new alias by using /alias NAME COMMAND. Now, /NAME will automatically expand to COMMAND. For example, this alias will let you list all damaged creeps by typing /damagedCreeps:

/alias damagedCreeps _.filter(Game.creeps, (c) => c.hits < c.hitsMax)

Aliases can also take parameters. There will be available in variables like $1, $2, etc. The entire passed string is available as $args. For example:

/alias hitsLeft "Creep " + $1 + " has " + Game.creeps[$1].hits + " hits left"
/hitsLeft Ryan

Plugin: Watch

The watch plugin will log an expression to your console on every tick. To install it, copy watch-client.js to your script and add some code to your loop function:

var watcher = require('watch-client');
exports.loop = function() {
  // Rest of your code...


There are two ways to watch expressions. You can log it to the console normally by using /watch console EXPR. You can also log to a status bar at the bottom of the screen using /watch status EXPR. For example, /watch status _.keys(Game.creeps).length will keep a count of the number of live creeps at the bottom of the terminal.

Plugin: HTML

The HTML plugin allows you to style the log output using the 'style' attribute of HTML tags. It converts the values for the style attributes to the relevant blessed tags. It should work with any html tags, though has only been tested with <div>, <span>, and <a>.

It currently supports: color, background, bold, and underline

  • Text color: style="color: #00FFFF; or style="color: blue;"
  • Background: style="background: #FFFF00;" or style="background: green;"
  • Bold: style="font-weight: bold;"
  • Underline: style="text-decoration: underline;"
<span style="color: green;">Hello, World!</span>

Multiple styles may be included in a single tag:

<span style="color: #FF0000; background: blue; font-weight: bold;">Red-on-blue bolded text</span>

Tags may be nested:

<span style="color: #FF0000;">This is red <span style="color: #00FF00;">This is green </span> <span style="font-weight: bold;">This is bold red</span></span>

//The same string, with newlines for visual clarity
<span style="color: #FF0000;">
    This is red 
    <span style="color: #00FF00;">This is green </span>
    <span style="text-decoration: underline;">This is red and underlined</span>


If you have feedback, bugs, or feature requests for multimeter, don't hesitate to look through the issues and add your thoughts. Please search to see if someone else has already filed a related issue before you submit a new one.

Multimeter is built for hacking! The easiest way to add a feature to multimeter is to make a new plugin for it. If you need to change something and it can't be done with a plugin, you can fork multimeter and submit a pull request. Ideally, you can add the necessary hooks so that other plugins can take advantage of them.
