JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
svelte-check
Advanced tools
The svelte-check npm package is a command-line tool designed to provide type checking and linting for Svelte projects. It leverages TypeScript and Svelte's own compiler to ensure that your Svelte components are free of type errors and adhere to best practices.
Type Checking
This command runs type checking on your Svelte project, ensuring that all TypeScript code within your Svelte components is type-safe. It helps catch type errors early in the development process.
npx svelte-check
Linting
This command runs linting on your Svelte project using the specified TypeScript configuration file. It helps enforce coding standards and best practices within your Svelte components.
npx svelte-check --tsconfig ./tsconfig.json
Watch Mode
This command runs svelte-check in watch mode, continuously checking your Svelte project for type errors and linting issues as you make changes. It provides real-time feedback during development.
npx svelte-check --watch
ESLint is a widely-used linting tool for JavaScript and TypeScript projects. While it is not specific to Svelte, it can be configured to work with Svelte projects using plugins like eslint-plugin-svelte3. Compared to svelte-check, ESLint offers more extensive linting rules and customization options but requires additional configuration for Svelte.
TypeScript is a superset of JavaScript that adds static typing. The TypeScript compiler (tsc) can be used to type-check Svelte projects, but it does not provide Svelte-specific linting. svelte-check combines TypeScript's type-checking capabilities with Svelte-specific linting, making it more tailored for Svelte projects.
Prettier is an opinionated code formatter that can be used to format Svelte files. While it does not provide type checking or linting, it ensures consistent code style across your project. svelte-check focuses on type checking and linting, whereas Prettier focuses on code formatting.
Provides diagnostics for things such as
Installation:
npm i svelte-check -g
Usage:
svelte-check
Installation:
npm i svelte-check --save-dev
Package.json:
{
// ...
"scripts": {
"svelte-check": "svelte-check"
// ...
},
// ...
"devDependencies": {
"svelte-check": "..."
// ...
}
}
Usage:
npm run svelte-check
--workspace <path to your workspace, where checking starts>
--outputFormat <human|human-verbose|machine>
Setting the --outputFormat
to machine
will format output in a way that is easier to read
by machines, e.g. inside CI pipelines, for code quality checks, ets.
Each row corresponds to a new record. Rows are made up of columns that are separated by a single space character. The first column of every row contains a timestamp in milliseconds which can be used for monitoring purposes. The second columns gives us the "row type", based on which the number and types of subsequent columns may differ.
The first row is of type START
and contains the workspace folder (wrapped in quotes).
Example:
1590680325583 START "/home/user/language-tools/packages/language-server/test/plugins/typescript/testfiles"
Any number of ERROR
or WARNING
records may follow. Their structure is identical and tells
us the filename, the line and column numbers, and the error message. The filename is relative
to the workspace directory. The filename and the message are both wrapped in quotes.
Example:
1590680326283 ERROR "codeactions.svelte" 1:16 "Cannot find module 'blubb' or its corresponding type declarations."
1590680326778 WARNING "imported-file.svelte" 0:37 "Component has unused export property 'prop'. If it is for external reference only, please consider using `export const prop`"
The output concludes with a COMPLETED
message that summarizes total numbers of files, errors,
and warnings that were encountered during the check.
Example:
1590680326807 COMPLETED 20 FILES 21 ERRORS 1 WARNINGS
If the application experiences a runtime error, this error will appear as a FAILURE
record.
Example:
1590680328921 FAILURE "Connection closed"
