Add Oxc checks and PR preview publishing

[AmanVarshney01]

Summary

• add oxlint and oxfmt to the repo with lint, lint:fix, format, and format:check scripts
• add baseline Oxc config and format the supported repo files
• keep templates/**/*.hbs out of oxfmt for now because some Handlebars templates do not parse cleanly yet
• update the publish workflow so same-repo PRs automatically publish preview builds to npm with dist-tags like create-prisma@pr18
• keep the existing main release flow, but gate it on lint, format check, typecheck, and build

Preview publish behavior

For a PR like #18, GitHub Actions now publishes a unique prerelease version of create-prisma and tags it with pr18 on npm.

That means reviewers can install the latest build for the PR with:

• bunx create-prisma@pr18
• npm install create-prisma@pr18
• yarn add create-prisma@pr18
• pnpm add create-prisma@pr18

Each new push to the PR republishes a fresh preview version behind the same pr18 tag.

Verification

• bun run lint
• bun run format:check
• bun run typecheck
• bun run build

Summary by CodeRabbit

• New Features

  • Added PR preview npm package publishing with per-PR distribution tags.

• Documentation

  • Expanded template support list; added new scripts (check, lint, format) to documentation; clarified preview package publishing workflow.

• Chores

  • Integrated code quality and formatting tools; enhanced release workflow with automated version validation and tagging.

Walkthrough

This PR introduces linting and formatting tools (oxlint and oxfmt) to the project, restructures CI/CD workflows for npm package previews and releases, updates package metadata configuration, and applies comprehensive code formatting across source and template files.

Changes

Cohort / File(s)	Summary
CI/CD Workflows .github/workflows/publish.yml	Modified root-level permissions to read-only, restructured concurrency handling for pull requests, and added new "preview" job for PR-based npm package publishing with tag derivation from PR numbers. Release workflow now triggers on commit messages starting with chore(release): and includes conditional version checks, git tag creation, and GitHub release steps.
Linting & Formatting Configuration .oxfmtrc.json, .oxlintrc.json	Added new configuration files for OxFormat and Oxlint tools, including schema paths, ignore patterns for templates, rule disablement (unicorn/no-empty-file), and environment settings.
Package Metadata & Scripts package.json	Updated to declare package as non-private, added repository metadata, files array, module type declaration, new scripts for linting/formatting (check, lint, lint:fix, format, format:check), and devDependencies for oxfmt and oxlint. Added engine constraints for Bun and Node.js versions.
Documentation README.md	Expanded usage section with new bun run check command, updated Prisma scaffolding paths, listed additional supported templates (hono, next, svelte, astro, nuxt, tanstack-start, turborepo), and documented new PR preview packaging workflow with dist-tag examples.
Source Code Formatting src/commands/create.ts, src/constants/db-packages.ts, src/index.ts, src/tasks/install.ts, src/tasks/prisma-postgres.ts, src/tasks/setup-addons.ts, src/tasks/setup-prisma.ts, src/templates/render-create-template.ts, src/templates/shared.ts, src/types.ts, src/ui/branding.ts, src/utils/package-manager.ts	Comprehensive code formatting changes including consolidation of multi-line imports to single-line, addition of trailing commas in parameter lists and object declarations, and reformatting of string literals and array expressions. Function signatures updated with trailing comma formatting but no behavioral changes.
Template Files templates/create/next/..., templates/create/svelte/..., templates/create/tanstack-start/..., templates/create/turborepo/...	Formatting normalization across template configuration and source files including indentation standardization (tabs to spaces), quote style normalization (single to double quotes), removal of trailing blank lines, and reformatting of array declarations and CSS font-family declarations.

420-428: 🧹 Nitpick | 🔵 Trivial

Consider extracting the nested ternary to improve readability.

The deeply nested ternary chain for resolving singletonPath works correctly but is difficult to scan. A helper function or early-return pattern would improve maintainability.

♻️ Optional refactor using a lookup array

+async function resolveSingletonPath(prismaProjectDir: string): Promise<string> {
+  const candidates = [
+    "src/lib/prisma.ts",
+    "src/lib/prisma.server.ts",
+    "src/lib/server/prisma.ts",
+    "server/utils/prisma.ts",
+  ];
+
+  for (const candidate of candidates) {
+    if (await fs.pathExists(path.join(prismaProjectDir, candidate))) {
+      return path.join(prismaProjectDir, candidate);
+    }
+  }
+
+  return path.join(prismaProjectDir, "src/client.ts");
+}

Then replace the nested ternary:

-  const singletonPath = (await fs.pathExists(path.join(prismaProjectDir, "src/lib/prisma.ts")))
-    ? path.join(prismaProjectDir, "src/lib/prisma.ts")
-    : (await fs.pathExists(path.join(prismaProjectDir, "src/lib/prisma.server.ts")))
-      ? path.join(prismaProjectDir, "src/lib/prisma.server.ts")
-      : (await fs.pathExists(path.join(prismaProjectDir, "src/lib/server/prisma.ts")))
-        ? path.join(prismaProjectDir, "src/lib/server/prisma.ts")
-        : (await fs.pathExists(path.join(prismaProjectDir, "server/utils/prisma.ts")))
-          ? path.join(prismaProjectDir, "server/utils/prisma.ts")
-          : path.join(prismaProjectDir, "src/client.ts");
+  const singletonPath = await resolveSingletonPath(prismaProjectDir);
