Fix Windows backslash path separators in React Router 7 SSR build output.

When you run react-router build on Windows, the server bundle declares:

var assetsBuildDirectory = "build\\client";

The backslash separator breaks path handling on POSIX servers (e.g. Linux deploys). This CLI rewrites only that assignment to use a forward slash:

var assetsBuildDirectory = "build/client";

It is surgical — it touches only the assetsBuildDirectory = "..." assignment, so unrelated regex/pattern escapes elsewhere in the bundle (e.g. "\\d{6}") are left intact. Running it twice is safe (idempotent).

Installation

npm install --save-dev @juncha9/rr7-build-fix

Usage

Run with no arguments to fix server/index.js in the known build directories (build/ and build_test/) — whichever exist:

npx rr7-build-fix

Wire it into your build scripts:

"scripts": {
  "build:prod": "react-router build --mode production && rr7-build-fix",
  "build:test": "react-router build --mode testprod  && rr7-build-fix"
}

Target a specific build directory or file:

rr7-build-fix build_test                 # fixes build_test/server/index.js
rr7-build-fix build/server/index.js      # fixes the file directly
rr7-build-fix build build_test           # multiple targets

A directory argument is resolved to <dir>/server/index.js; a file argument is used as-is.

Programmatic API

import { fixAssetsBuildPath } from "@juncha9/rr7-build-fix";

const result = fixAssetsBuildPath("build/server/index.js");
// { filePath, changed, before?, after? }
