slim-lang-loader

library0.0.9jsnpmunverified

Webpack loader that transforms Slim template files into HTML strings embedded in JavaScript. Version 0.0.9 (latest as of 2019) wraps the Ruby `slimrb` CLI, meaning it requires Ruby and the Slim gem installed globally. Unlike other Slim-to-HTML converters, this is a true Ruby-based conversion, preserving full Slim feature support (e.g., inline Ruby, Slim options). The loader outputs HTML that can be used as string templates or passed to further loaders (e.g., html-loader). Last updated in 2019; no active development, but functional for projects already using Ruby Slim.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import html from 'html-loader!./file.slim'

✗ const html = require('./file.slim') // without html-loader, file content is just HTML string, not a module

Loader outputs raw HTML string; typically used with html-loader to export the string as a module.

slim-lang-loader

✓ { test: /\.slim$/, use: ['slim-lang-loader'] }

✗ { test: /\.slim$/, loader: 'slim-lang-loader' } // legacy syntax, also works but string form is deprecated in webpack 4+

Webpack config: use the rule object with 'use' array for clarity. Must be placed before loaders that expect JS or other compiled output.

options

✓ const config = { module: { rules: [ { test: /\.slim$/, use: [ { loader: 'slim-lang-loader', options: { slimOptions: { disable_escape: true } } } ] } ] } }

✗ options: { 'disable_escape': true } // missing 'slimOptions' wrapper

Slim options must be wrapped in a 'slimOptions' object per the loader's API.

Configures webpack to process .slim files via slim-lang-loader, then imports a Slim template as an HTML string.

// webpack.config.js module.exports = { module: { rules: [ { test: /\.slim$/, use: [ 'slim-lang-loader' ] } ] }, resolve: { extensions: ['.js', '.slim'] } }; // template.slim doctype html html head title Example body h1 Hello from Slim! // app.js import html from './template.slim'; document.body.innerHTML = html;

Known issues

gotchaRequires Ruby and slim gem installed globally; not a pure Node.js solution.

fix

Install Ruby and run 'gem install slim' before building.

affects: all

gotchaLoader spawns a child process to run slimrb, which can be slow for many files.

fix

Use a cache-loader or only for limited use. Consider alternative Slim-to-HTML loaders that are JS-only.

affects: all

gotchaOutput is raw HTML string; must be used with another loader (e.g., html-loader) to be importable as a module.

fix

Chain with html-loader or manually wrap the output in module.exports.

affects: all

gotchaNo built-in cache; re-runs slimrb on every build.

fix

Use webpack's cache-loader or external caching.

affects: all

Errors

Common errors & fixes

Error: spawn slimrb ENOENT

Ruby or slim gem not installed, or slimrb not in PATH.

fix

Install Ruby and run 'gem install slim'. Verify 'which slimrb' works.

Module parse failed: Unexpected token (1:0) You may need an appropriate loader to handle this file type.

Slim file processed without slim-lang-loader or misconfigured rule.

fix

Add { test: /\.slim$/, use: ['slim-lang-loader'] } to webpack config.

Invalid or unexpected token

Loaded from .slim file returns HTML string but code expects a module export.

fix

Use 'html-loader' after slim-lang-loader, or wrap the require/import to handle a string.
