What are Machines?

The machine specification is an open standard for Javascript functions. Each machine has a single, clear purpose—whether it be sending an email, translating a text file, or fetching a web page. But whereas traditional functions are supposed to have only a single result, machines are aware of multiple possible outcomes. Machines are self-documenting, quick to implement, and simple to debug.


Machines are published to NPM through the use of machinepacks, or node modules that implement a standardized interface. In other words, when you require() a machinepack, you always know exactly which actions are available, what to provide as input values, and what you're going to get back.

Self-documenting.

Since every machine follows the same conventions as described in the machine spec, documentation can be created automatically simply by parsing their source file. All of the documentation on node-machine.org is rendered via an automated process.

Error-preventing.

Say goodbye to unforseen consequences. Machines validate their inputs automatically, and by using the concept of exits to control program flow, they give developers an unprecedented degree of error-handling.

Universal.

No more trial-and-error when integrating a new third-party module into your project: every machine follows the same easy-to-use interface.
