The Unpaid Backbone of Open Source: Solo Maintainers Face Increasing Security Demands
Solo open source maintainers face burnout and security challenges, with 60% unpaid and 60% considering quitting.
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.
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"}
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.
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.
A list of objects, bound by their prototype chain.
Used in npm's config stuff.
