@stackline/brace

A compatibility-first Browserify build of the modern Ace Editor. It preserves Brace deep imports, embeds workers for browser bundles, supports TypeScript 3.9, and has zero runtime dependencies.

Install

Use the scoped package directly:

npm install @stackline/brace

Or replace brace without changing existing source imports:

npm install brace@npm:@stackline/brace@^1.0.0

Existing Brace code

const ace = require('brace');
require('brace/mode/javascript');
require('brace/theme/monokai');

const editor = ace.edit('editor');
editor.session.setMode('ace/mode/javascript');
editor.setTheme('ace/theme/monokai');

Scoped imports

const ace = require('@stackline/brace');
require('@stackline/brace/mode/typescript');
require('@stackline/brace/theme/github');

const editor = ace.edit('editor');
editor.session.setMode('ace/mode/typescript');
editor.setTheme('ace/theme/github');

ES modules are supported at the root:

import ace from '@stackline/brace';
import '@stackline/brace/mode/javascript.js';
import '@stackline/brace/theme/monokai.js';

What is preserved

Contract	Status
brace@0.11.1 root API	Preserved
Historical mode, theme, extension, keybinding, snippet, and worker paths	Preserved
acequire loader	Preserved, with require also available
Browserify side-effect imports	Preserved
npm alias installation as brace	Tested from each registry
TypeScript 3.9	Tested
Runtime dependencies	Zero

The generated runtime uses ace-builds@1.44.0 and includes 206 modes, 48 themes, 29 extensions, 206 snippet paths, and 10 inline workers. These counts are generated from the pinned build input rather than maintained by hand.

Inline workers

Modes register their referenced worker source as a Blob URL when loaded in a browser. This prevents the common worker-javascript.js 404 in bundled deployments.

Consumer configuration always wins:

const ace = require('@stackline/brace');

ace.config.setModuleUrl(
  'ace/mode/javascript_worker',
  'https://cdn.example.com/worker-javascript.js'
);

require('@stackline/brace/mode/javascript');

The package will not overwrite an existing module URL. Applications with a strict Content Security Policy can provide explicit worker URLs or disable workers through Ace's standard session API.

Supply chain

Ace is an exact development-time generation input and is not installed for consumers. Generated assets are committed and the release records the upstream npm shasum and integrity value in dist/build-meta.json.

Every release gate covers:

• all paths published by brace@0.11.1;
• current generated inventory;
• Browserify and esbuild bundles;
• a real Chrome editor with a functioning inline worker;
• TypeScript 3.9 and current TypeScript;
• direct and npm-alias installation from the packed tarball and registries;
• package metadata, documentation, runtime audit, checksums, and SBOM.
