proto-list

What is proto-list?

The proto-list package is a simple data structure that manages a list of objects, each of which inherits from the one before it. This is useful for managing a chain of configurations or settings where each level of the list can override properties from the previous one.

What are proto-list's main functionalities?

Create and manage a prototypal list

This feature allows you to create a new prototypal list and manage it by pushing objects onto the list. Each object in the list inherits properties from the previous one.

{"var ProtoList = require('proto-list');\nvar list = new ProtoList();\nlist.push({a: 1});\nlist.push({b: 2});\nconsole.log(list.length); // 2\nconsole.log(list.a); // 1\nconsole.log(list.b); // 2"}

Access inherited properties

This feature demonstrates how properties in the list can be overridden by objects further down the list. The last object's properties take precedence.

{"var ProtoList = require('proto-list');\nvar list = new ProtoList();\nlist.push({a: 1});\nlist.push({b: 2});\nlist.push({a: 'overridden'});\nconsole.log(list.a); // 'overridden'\nconsole.log(list.b); // 2"}

Other packages similar to proto-list

config-chain

The config-chain package is similar to proto-list in that it allows you to create a chain of configuration sources. It is more complex and feature-rich, offering additional functionality such as file loading, command-line argument integration, and environment variable support.

rc

The rc package is another configuration management library that can be used to handle hierarchical configurations. It is similar to proto-list but also includes support for configuration files, environment variables, command-line arguments, and custom defaults.
