FlowForger for VS Code

Build Power Automate and Logic Apps flows as TypeScript — with IntelliSense, local debugging, and compilation to Logic Apps JSON.

Features

• IntelliSense: Autocomplete for ctx.* methods, connectors, action names, and variables
• Schema Completions: Inside ctx.connectors.dataverse.* / ctx.connectors.sharepoint.* calls, autocomplete real table logical names, SharePoint sites and lists, and column/field names (in item: {...} keys and $select/$orderby/$filter strings), read live from your environment. Run FlowForger: Connect Data Sources once to sign in — typing never triggers a sign-in prompt on its own.
• Diagnostics: Real-time error detection for invalid references, missing decorators
• Hover Documentation: Rich documentation for methods and decorators
• Snippets: 20+ code snippets for common patterns
• Syntax Highlighting: Special highlighting for FlowForger decorators and methods
• Edit & Continue: While paused, edit the flow and press Restart (Ctrl+Shift+F5) — the run restarts under the hood, replaying recorded connector/HTTP responses (unchanged calls are never re-sent) and fast-forwarding back to the paused position or the first divergence. Restarting while not paused does a normal clean run.
• Set Next Statement: While paused, right-click a line and choose "Jump to Cursor" to move the execution point — backward to re-execute with live connector calls, forward to skip. From a loop-iteration or branch-child pause, a backward jump restarts and replays up to the target instead (console variable edits are not preserved).

File Extension

FlowForger DSL files use the .ff.ts extension.

Quick Start

1. Create a new file with .ff.ts extension
2. Start typing flow-class to use the snippet
3. Use ctx. to see available methods

Example

Create hello-flow.ff.ts:

@Flow('hello-flow')
class HelloFlow {
  @ManualTrigger()
  trigger() {}

  @Action()
  async run(ctx: FlowContext) {
    // Build a message with a Compose action
    await ctx.compose('Greeting', { message: 'Hello from FlowForger' });

    // POST it to httpbin, which echoes the body back
    await ctx.http('CallHttpBin', {
      method: 'POST',
      url: 'https://httpbin.org/post',
      body: ctx.outputs('Greeting'),
    });

    // Pull the echoed message out of the response
    await ctx.compose('Echo', ctx.body('CallHttpBin')?.['json']);
  }
}

No imports needed. @Flow, @ManualTrigger, @Action, and FlowContext are ambient globals recognized by the FlowForger compiler and this extension. Reference a Compose action's output with ctx.outputs('Name') and an HTTP action's response body with ctx.body('Name').

Commands

• FlowForger: Restart Language Server - Restart the LSP server
• FlowForger: Compile to IR - Compile current file to FlowIR JSON
• FlowForger: Compile to Logic Apps JSON - Compile to Power Automate format

Settings

Requirements

None — the language server, compiler, emitter, and debugger are fully bundled with the extension. No workspace setup or Node.js installation required.

For command-line workflows (CI, deployment), see the flowforger CLI on npm.
