TypeScript Prettier Language Service Plugin

0.0.3 verified Sat Apr 25 auth: no javascript abandoned

This package provides a TypeScript language service plugin designed to integrate Prettier formatting capabilities directly into development environments. It supports both range and document formatting, aiming to ensure consistent code style within editors that leverage the TypeScript Language Server. The current and only published version is 0.0.3, indicating it is an early-stage, experimental project. As of April 2026, it appears to be abandoned, with no updates or new releases in approximately three years, suggesting a lack of ongoing maintenance or development. Its primary differentiator was the direct integration of Prettier into the TypeScript language service, enhancing developer experience by providing automatic formatting within compatible IDEs, but its practical utility is significantly limited by its experimental status and lack of active maintenance.

Common errors

error Plugin 'typescript-prettier-language-service' failed to load ↓

cause The plugin is not correctly installed, the `tsconfig.json` configuration is incorrect, or there's an incompatibility with the installed TypeScript version.

fix

Ensure typescript-prettier-language-service is present in your node_modules. Verify that it's correctly listed in the compilerOptions.plugins array in your tsconfig.json. Check that your typescript and prettier versions meet the plugin's peer dependency requirements.

error Prettier formatting not applied in editor (e.g., VS Code) despite plugin being enabled. ↓

cause The plugin might be active but not correctly invoked for formatting, or it's conflicting with another formatting extension or editor setting.

fix

Check your editor's settings to confirm that the TypeScript language service is designated as the primary formatter for TypeScript files. Temporarily disable other formatting extensions to rule out conflicts. Review your editor's output logs for any messages from the TypeScript server regarding the plugin.

Warnings

breaking This package is in an extremely early development stage (version 0.0.3) and appears to be abandoned. Its API is highly unstable and should not be relied upon for production environments, as any future development (which is unlikely) would likely introduce breaking changes without notice. ↓

fix Avoid using this package for new projects. Consider more mature and actively maintained Prettier integrations, such as dedicated editor extensions or format-on-save utilities, for reliable formatting.

gotcha The project's development environment is documented as Replit, which might indicate a less conventional or community-driven maintenance model. Users should not expect regular updates, bug fixes, or community support channels typical of mainstream open-source projects. ↓

fix Before integration, thoroughly verify the project's current activity and support availability. Given its abandoned status, it's best to assume no support will be available.

deprecated Due to its abandoned status and low version number, this plugin is unlikely to be compatible with newer versions of TypeScript or Prettier, potentially leading to runtime errors, inconsistent formatting, or complete failure to load. ↓

fix Always ensure compatibility with your installed `typescript` and `prettier` versions. It is strongly recommended to migrate to actively maintained alternatives that explicitly support current toolchain versions.

Install

npm install typescript-prettier-language-service

yarn add typescript-prettier-language-service

pnpm add typescript-prettier-language-service

Quickstart

This `tsconfig.json` snippet demonstrates how to enable the `typescript-prettier-language-service` plugin within your TypeScript project. This configuration instructs the TypeScript language server to load the plugin, which then provides Prettier-based formatting services to your IDE or editor.
