Google TypeScript Style
gts is Google's TypeScript style guide, and the configuration for our formatter, linter, and automatic code fixer. No lint rules to edit, no configuration to update, no more bike shedding over syntax.
To borrow from standardjs:
- No configuration. The easiest way to enforce consistent style in your project. Just drop it in.
- Automatically format code. Just run
gts fixand say goodbye to messy or inconsistent code.
- Catch style issues & programmer errors early. Save precious code review time by eliminating back-and-forth between reviewer & contributor.
- Opinionated, but not to a fault. We recommend you use the default configuration, but if you need to customize compiler or linter config, you can.
The easiest way to get started is to run:
npx gts init
How it works
When you run the
npx gts init command, it's going to do a few things for you:
- Adds an opinionated
tsconfig.jsonfile to your project that uses the Google TypeScript Style.
- Adds the necessary devDependencies to your
- Adds scripts to your
lint: Lints and checks for formatting problems.
fix: Automatically fixes formatting and linting problems (if possible).
clean: Removes output files.
compile: Compiles the source code using TypeScript compiler.
prepare: convenience integrations.
- If a source folder is not already present it will add a default template project.
The commands above will all run in the scope of the current folder. Some commands can be run on individual files:
gts lint index.tsgts lint one.ts two.ts three.tsgts lint *.ts
Working with eslint
Under the covers, we use eslint to enforce the style guide and provide automated fixes, and prettier to re-format code. To use the shared
eslint configuration, create an
.eslintrc in your project directory, and extend the shared config:
If you don't want to use the
gts CLI, you can drop down to using the module as a basic
eslint config, and just use the
$ eslint --fix
This opens the ability to use the vast
eslint ecosystem including custom rules, and tools like the VSCode plugin for eslint:
