Kill Switch Hidden in npm Packages Typosquatting Chalk and Chokidar
Socket researchers found several malicious npm packages typosquatting Chalk and Chokidar, targeting Node.js developers with kill switches and data theft.
jest-preset-stylelint
Advanced tools
Jest preset for Stylelint plugins.
Install the preset alongside Jest and Stylelint:
npm install jest-preset-stylelint jest stylelint --save-dev
Add the preset to your jest.config.js
or jest
field in package.json
:
{
"preset": "jest-preset-stylelint"
}
Optionally, you can avoid specifying plugins
in every schema by defining your own setup file to configure the testRule
/testRuleConfigs
functions.
This is useful if you have many tests. There are two additional steps to do this:
Create jest.setup.js
in the root of your project. Provide plugins
option to getTestRule
/getTestRuleConfigs
:
import { getTestRule, getTestRuleConfigs } from "jest-preset-stylelint";
import myPlugin from "./my-plugin.js";
const plugins = [myPlugin];
global.testRule = getTestRule({ plugins });
global.testRuleConfigs = getTestRuleConfigs({ plugins });
Add jest.setup.js
to your jest.config.js
or jest
field in package.json
:
{
"preset": "jest-preset-stylelint",
"setupFiles": ["<rootDir>/jest.setup.js"]
}
If you get a segmentation fault while running the preset on Node.js 18, you can use jest-light-runner:
{
"preset": "jest-preset-stylelint",
"runner": "jest-light-runner"
}
This preset exposes the following global functions as a helper.
See also the type definitions for more details.
testRule
The testRule
function enables you to efficiently test your plugin using a schema.
For example, we can test a plugin that enforces and autofixes kebab-case class selectors:
// my-plugin.test.js
import myPlugin from "./my-plugin.js";
const plugins = [myPlugin];
const {
ruleName,
rule: { messages }
} = myPlugin;
testRule({
plugins,
ruleName,
config: [true, { type: "kebab" }],
fix: true,
accept: [
{
code: ".class {}",
description: "simple class selector"
},
{
code: ".my-class {}",
description: "kebab class selector"
}
],
reject: [
{
code: ".myClass {}",
fixed: ".my-class {}",
description: "camel case class selector",
message: messages.expected(),
line: 1,
column: 1,
endLine: 1,
endColumn: 8
},
{
code: ".MyClass,\n.MyOtherClass {}",
fixed: ".my-class,\n.my-other-class {}",
description: "two pascal class selectors in a selector list",
warnings: [
{
message: messages.expected(),
line: 1,
column: 1,
endLine: 1,
endColumn: 8
},
{
message: messages.expected(),
line: 2,
column: 1,
endLine: 2,
endColumn: 13
}
]
}
]
});
testRuleConfigs
The testRuleConfigs
function enables you to test invalid configs for a rule.
For example:
testRuleConfigs({
plugins,
ruleName,
accept: [
{
config: "valid"
}
],
reject: [
{
config: "invalid"
},
{
config: [/invalid/],
description: "regex is not allowed"
}
]
});
