スタート アップ ガイド

Install the CLI, scaffold a JavaScript or TypeScript function project, and run your first function locally.

This page walks you through installing the CLI, scaffolding a project, and running your first JavaScript function locally.

前提条件

• Node.js 20 or later.
• The uip CLI with the functions tool:

npm install -g @uipath/cli
uip tools install @uipath/function-tool

• A UiPath account with access to Orchestrator, for publishing and invoking.

プロジェクトのスキャフォールディング

uip function new my-functions -l ts
cd my-functions

TypeScript is the default; pass -l js for JavaScript, or --empty to skip the sample function.

The scaffold creates:

ファイル	目的
functions/hello.ts	Your function logic — one function per file. Starts as a runnable example.
functions/_*.ts	Shared helpers. A leading underscore marks a file as a helper, so it gets no entry point and no trigger.
uipath.json	Maps function names to their entry points.
package.json, tsconfig.json	Standard project files.

最初の関数を記述する

import { defineFunction, defineSchema } from "@uipath/coded-functions-js-sdk";

interface HelloInput {
  name: string;
}

interface HelloOutput {
  message: string;
}

export default defineFunction({
  name: "hello",
  method: "POST",
  path: "/hello",
  input: defineSchema<HelloInput>(),
  output: defineSchema<HelloOutput>(),
  handler: async (input) => ({ message: `Hello, ${input.name}!` }),
});

defineSchema<T>() derives the JSON Schema from your TypeScript interface, so the same type declares the contract and types the handler. In JavaScript projects, pass a JSON Schema object instead.

The method and path make this function callable over HTTP. Omit both and it runs only as a job — see Building JavaScript functions.

ローカルで実行する

uip function serve

This starts a hot-reload server on http://localhost:7070. Call the function:

curl -X POST http://localhost:7070/hello \
  -H "Content-Type: application/json" \
  -d '{"name":"Alice"}'
# {"message":"Hello, Alice!"}

To reach Orchestrator from a local run, put UIPATH_ACCESS_TOKEN, UIPATH_BASE_URL, UIPATH_ORG_ID and UIPATH_TENANT_ID in a .env file at the project root. serve loads it on both supported runtimes.

次のステップ

• Building JavaScript functions — contracts, errors, and the two function shapes.
• HTTP triggers and routing — routes, path parameters, and calling a deployed function.
• Packaging and publishing — deploy to Orchestrator.
• CLI reference — every command and flag.
