SmolYAML

SmolYAML is a minimalistic parser for YAML-like data.

YAML is a complex spec.

An npm install yaml weighs about 100kb of minified JavaScript.

SmolYAML is used in a static site generator that tries tries to be as minimalistic as possible. That static site generator depends on YAML for parsing frontmatter, a block of meta data in template files. But including the full YAML implementation would quite bloat it.

SmolYAML tries to address that by implementing only a small subset of the specification. To be fair, it's an opinionated one that is (opinionatedly) considered good enough to parse frontmatter meta data.

In roughly 2KB of minified JavaScript.

Usage

npm i @sissijs/smolyaml

import { smolYAML } from '@sissijs/smolyaml';

const metadata = `
name: Lea
description: Lea is a Web Developer
age: 42
details:
  frontend: She loves doing Front of the Frontend work
  fullstack: But she really hates being called a fullstack developer
`

console.log(smolYAML(metadata));

Limitations

• Right now, multi-line string values aren't supported.
• Only a parser is provided.
