Reusable code, without the clutter

A calmer directory for practical developer snippets.

CodeSnippets.ca organizes short, useful patterns and utilities while keeping the canonical code on GitHub Gist.

const stream = fs.createReadStream(file);
const rl = readline.createInterface({ input: stream });

for await (const line of rl) {
  await processLine(line);
}

Approach

The website indexes. The Gist remains canonical.

Describe the snippet

Add title, language, category, tags, difficulty, and a short use case to the JSON data or collection front matter.

Link to the Gist

Keep the code, revisions, comments, and raw file access on GitHub Gist.

Make it discoverable

Jekyll generates clean pages, while the small script handles instant filtering.
