Node API

TypeScript-typed API for integrating GaleforceCSS into custom tooling.

npm install -D @coralogix/galeforcecss

compile()

One-shot. Spawns the binary, compiles, exits.

import { compile } from '@coralogix/galeforcecss'

const { css, diagnostics } = await compile({
  candidates: ['flex', 'hover:bg-blue-500', 'md:px-4'],
  inputCss: '@tailwind utilities;\n',
  config: { corePlugins: { preflight: false } },
})

interface CompileInput {
  candidates?: string[]   // class names to compile
  inputCss?: string       // CSS with @tailwind directives (default: '@tailwind utilities;')
  config?: object         // resolved Tailwind config (default: Tailwind default)
  content?: string[]      // content roots (alternative to candidates)
}

interface CompileOutput {
  css: string
  diagnostics: Diagnostic[]
}

createCompileStream()

Keeps the Rust binary alive between calls. Use this for Vite plugins, language servers, and any tool that compiles repeatedly.

import { createCompileStream } from '@coralogix/galeforcecss'

const stream = createCompileStream()

const a = await stream.compile({ candidates: ['flex'] })
const b = await stream.compile({ candidates: ['block', 'flex'] })

const files = await stream.scanPerFile(['src'])
// { 'src/App.tsx': ['flex', 'text-red-500', …], … }

const merged = await stream.scan(['src/App.tsx'])

stream.close()

Method	Returns
compile(input)	CompileOutput
scan(paths)	merged string[] of candidates
scanPerFile(roots)	Record<string, string[]>
close()	shuts down the background process

loadConfig() / findConfigPath()

import { loadConfig, findConfigPath } from '@coralogix/galeforcecss'

const configPath = findConfigPath()
const { resolved } = await loadConfig({ path: configPath ?? undefined })

resolved is the JSON-serialisable config object Galeforce consumes.

Diagnostics

const { diagnostics } = await compile({ candidates: ['bogus-[100xp]'] })

for (const d of diagnostics) {
  console.log(d.severity, d.code, d.message, d.candidate)
}

Field	Type	Description
severity	'error' | 'warning' | 'info'	Severity level.
code	string	Machine-readable code (e.g. unsupported-candidate).
message	string	Human-readable description.
candidate	string | undefined	The triggering candidate, if applicable.

See Unsupported features for the full code list.
