👑 warekit

The CLI for WareKit — scaffold and manage NetSuite apps built with React.

A Masterpiece Will Always Require Effort.

npx warekit new user-event sync-customer --record CUSTOMER

📟 Commands

Options: --methods a,b, --record TYPE, --dry.

🧭 Script types

Governance is the decision the type actually turns on. Every script gets a usage-unit budget per execution, and exceeding it throws SSS_USAGE_LIMIT_EXCEEDED mid-request.

search.create().run() costs 10 units and record.load() costs 5, so a Suitelet doing 100 record loads is already over budget while a RESTlet has room. Reach for a RESTlet when an endpoint touches many records.

client and user-event are triggered by NetSuite on a record type, not over a URL, so they need --record and are deliberately not added to the endpoint registry.

map-reduce and scheduled are invoked by the scheduler or task.create(), not by a request, so their deployments carry a <recurrence> and ship as NOTSCHEDULED — you pick the schedule in the UI after deploy. Map/Reduce gets its 10,000 units per stage call, which is why a job too big for a Scheduled script fits comfortably once you split it across map or reduce.

📋 What it writes

1. The SuiteScript file, in the folder your manifest declares

2. The SDF object, with a filename matching its scriptid

3. The deploy.xml <path> when the folder is new

4. Runtime registration, for URL-addressed types only

Step 3 is the one that bites. Scripting/suitelets/* is usually already globbed, but your first RESTlet lives in a folder deploy.xml has never heard of, and SDF fails the entire deploy on it.

It also refuses names that would breach NetSuite's 40-character script-ID cap before writing anything, rather than at validation time where the error never mentions length.

⚙️ warekit.json

The CLI writes only where a project tells it to. Every project carries a manifest at its root:

{
  "version": 1,
  "kit": "netsuite",
  "edition": "lite",
  "identity": {
    "publisherId": "com.amware",
    "projectId": "myapplication",
    "scriptPrefix": "amw"
  },
  "paths": {
    "suiteapp": "apps/suiteapp/template",
    "scripting": {
      "suitelet": "Scripting/suitelets",
      "restlet": "Scripting/restlets",
      "client": "Scripting/client",
      "user-event": "Scripting/user-event",
      "map-reduce": "Scripting/map-reduce",
      "scheduled": "Scripting/schedule"
    },
    "objects": "Objects/scripts",
    "deployXml": "deploy.xml",
    "endpointRegistry": "FileCabinet/SuiteApps/{suiteApp}/Scripting/suitelets/{prefix}_sl_urls.js"
  }
}

Found by walking up from the working directory, the way git finds .git. A missing or malformed manifest is a hard error rather than a guess — guessing means scaffolding into the wrong folder and failing at deploy time, which is far more expensive to diagnose.

{suiteApp} and {prefix} are substituted, so the manifest stays valid after you change your project identity.

edition is lite or pro. The CLI reads it rather than sniffing the directory, so a Pro-only command fails with a clear message instead of half running against a Lite checkout. warekit info prints it.

📦 Kits

warekit create clones the Lite kit. Pro is in development.

The framework is in the name because a Next.js kit is planned for hybrid SuiteApps: a frontend on Vercel that reaches NetSuite from its API routes, over OAuth 2 for user sign-in or token-based auth for server-to-server calls, rather than running inside a Suitelet on the session cookie.

Both kinds ship an SDF project and both are scaffolded by this CLI — the SuiteScript backend is the same work either way, and warekit new does not care where the frontend is hosted. The kits differ only in their kit id, so a kit-specific command can tell them apart without inspecting the tree.

🤖 MCP server

A second binary exposes the same generator over MCP, so agents and humans produce identical output.

{
  "mcpServers": {
    "warekit": { "command": "npx", "args": ["-y", "warekit-mcp"] }
  }
}

Tools: warekit_script_types, warekit_project_info, warekit_new_script.

Every tool takes an explicit cwd — an MCP server's working directory is whatever the host launched it in, which is rarely your project.

📄 Licence

MIT. The CLI is free and open. The kits it scaffolds are a separate, commercially licensed product.

The rule that makes this work: commands parse, utils do. mcp.ts imports from utils/, never from commands/, so the CLI and the MCP server run the same code and cannot drift. A command file should be argument parsing, prompting, and one call into a util.

Adding a command

1. src/commands/<name>/<name>.command.ts exporting a function that returns a Command.

2. Put the work in src/utils/<verb>-<noun>.ts — not in the command — so the MCP server can expose it too.

3. Register it in src/index.ts with program.addCommand(...).

Subcommands nest: a plugins add command would be commands/plugins/plugins.command.ts plus commands/plugins/add/add.command.ts.

Adding a script type

One entry in SCRIPT_TYPES and one source function in src/templates/. No command changes — Map/Reduce, Scheduled, Portlet and Mass Update all fit the existing shape.
