strip-test-selectors

library0.1.0jsnpmunverified

A Babel plugin that strips data-test-* attributes from Ember.js templates and properties from JavaScript objects in production builds. Current stable version is 0.1.0, released as part of the ember-test-selectors monorepo. It is designed for Embroider+Vite apps (Ember 3.28+, Ember CLI 4.12+, Node.js 18+). Unlike the classic ember-test-selectors addon which works with classic Ember builds, this package provides granular Babel plugins for Vite-based setups, giving developers control over when stripping occurs via environment variables.

Verified usage

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

stripPropertiesPlugin

✓ import { stripPropertiesPlugin } from 'strip-test-selectors'

✗ const stripPropertiesPlugin = require('strip-test-selectors').stripPropertiesPlugin

ESM import is preferred but CommonJS require works if using CJS. The plugin strips data-test-* properties from JavaScript objects.

default (AST transform plugin)

✓ import stripTestSelectors from 'strip-test-selectors'

✗ import { stripTestSelectors } from 'strip-test-selectors'

The default export is the AST transform plugin for stripping data-test-* attributes from templates. Named import will fail.

types

✓ import type { StripTestSelectorsPlugin } from 'strip-test-selectors'

✗ import { StripTestSelectorsPlugin } from 'strip-test-selectors'

Type imports should use 'import type' to avoid runtime import. The library ships TypeScript declarations.

Configures Babel to strip data-test-* from templates and JS objects only when STRIP_TEST_SELECTORS environment variable is set, typically for production builds.

// babel.config.cjs const { stripPropertiesPlugin } = require('strip-test-selectors'); module.exports = { plugins: [ [ 'babel-plugin-ember-template-compilation', { compilerPath: 'ember-source/dist/ember-template-compiler.js', enableLegacyModules: ['@ember/template-compiler'], transforms: [ ...(process.env.STRIP_TEST_SELECTORS ? [require('strip-test-selectors').default] : []), ], }, ], ...(process.env.STRIP_TEST_SELECTORS ? [stripPropertiesPlugin] : []), ], };

Debug

Known issues

gotchaThis package only works with Embroider+Vite apps, not classic Ember builds. Classic builds must use ember-test-selectors addon.

fix

Use ember-test-selectors package for classic Ember apps, or migrate to Embroider+Vite.

affects: >=0.1.0

gotchaThe default export is the AST transform for templates, not a named export. Doing import { stripTestSelectors } will fail with 'undefined'.

fix

Use import stripTestSelectors from 'strip-test-selectors' for the template plugin.

affects: >=0.1.0

breakingRequires Node.js 18+ and Ember 3.28+. Older versions are not supported.

fix

Update Node.js to 18+ and Ember to 3.28+.

affects: >=0.1.0

gotchaYou are responsible for configuring when stripping occurs via environment variable; there is no automatic production detection.

fix

Set STRIP_TEST_SELECTORS=true in your production build script.

affects: >=0.1.0

gotchaThe plugin only strips attributes starting with 'data-test-'. Custom prefixes or suffixes are not supported.

fix

Use data-test-* prefix for all test selectors.

affects: >=0.1.0

Errors

Common errors & fixes

TypeError: Cannot destructure property 'stripPropertiesPlugin' of 'require(...)' as it is undefined.

Using old named import syntax for default export or incorrect package path.

fix

Use stripPropertiesPlugin as a named export: import { stripPropertiesPlugin } from 'strip-test-selectors'

Error: Cannot find module 'babel-plugin-ember-template-compilation'

Missing peer dependency babel-plugin-ember-template-compilation.

fix

Install it: npm install -D babel-plugin-ember-template-compilation

AssertionError [ERR_ASSERTION]: The plugin expected an object for 'transforms', got undefined.

babel-plugin-ember-template-compilation config missing transforms array.

fix

Provide transforms array in plugin options, e.g., transforms: [stripTestSelectors]
