Installation

Requirements

• Node.js ≥ 22
• pnpm ≥ 10 (npm and yarn also work)

Install the package

pnpm add @lapidist/dsr

DSR requires @lapidist/dtif-parser as a peer dependency. If your project doesn't already have it, install it alongside DSR:

pnpm add @lapidist/dsr @lapidist/dtif-parser

TypeScript

DSR ships full TypeScript definitions. No @types package is needed. Ensure your tsconfig.json sets moduleResolution to "NodeNext" or "Bundler" to resolve the package exports correctly:

{
  "compilerOptions": {
    "module": "NodeNext",
    "moduleResolution": "NodeNext"
  }
}

Import paths

DSR uses package export conditions. Import from the correct sub-path for your use case:

Sub-path	Contents
@lapidist/dsr	All public types and re-exports
@lapidist/dsr/environments/node	NodeEnvironment
@lapidist/dsr/environments/browser	BrowserEnvironment
@lapidist/dsr/environments/edge	EdgeEnvironment
@lapidist/dsr/dsql	DSQLClient
