Formfire Implementation Plan

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

Goal: Build an Obsidian plugin for structured data input via forms that creates notes or updates frontmatter.

Architecture: A+B Hybrid — pragmatic like Promptfire, with clean separation like Logfire. Three core layers: FormStore (settings CRUD), FieldRenderers (UI per type), FormProcessor (note creation/frontmatter update). Visual Form Builder in Settings, FormModal for filling out, Sidebar for discovery.

Tech Stack: Obsidian Plugin API, TypeScript 5.6, esbuild, CSS with Obsidian CSS variables.

Reference plugins: obsidian-promptfire (flat structure, settings patterns, CSS conventions), obsidian-logfire (layered architecture, deepMerge, settings tab style).

Task 1: Project Scaffolding

Files:

Create: package.json
Create: manifest.json
Create: tsconfig.json
Create: esbuild.config.mjs
Create: .gitignore

Step 1: Create package.json

{
  "name": "obsidian-formfire",
  "version": "0.1.0",
  "description": "Structured data input for Obsidian – forms that create notes or update frontmatter",
  "main": "main.js",
  "scripts": {
    "dev": "node esbuild.config.mjs",
    "build": "node esbuild.config.mjs production"
  },
  "devDependencies": {
    "@types/node": "^22.0.0",
    "builtin-modules": "^4.0.0",
    "esbuild": "^0.24.0",
    "obsidian": "latest",
    "typescript": "^5.6.0"
  }
}

Step 2: Create manifest.json

{
  "id": "formfire",
  "name": "Formfire",
  "version": "0.1.0",
  "minAppVersion": "1.5.0",
  "description": "Structured data input for Obsidian – forms that create notes or update frontmatter",
  "author": "Luca",
  "isDesktopOnly": true
}

Step 3: Create tsconfig.json

Follow Logfire's pattern (ES2022, strict):

{
  "compilerOptions": {
    "baseUrl": ".",
    "inlineSourceMap": true,
    "inlineSources": true,
    "module": "ESNext",
    "target": "ES2022",
    "strict": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "moduleResolution": "node",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "importHelpers": true,
    "isolatedModules": true,
    "skipLibCheck": true,
    "lib": ["DOM", "ES2022"]
  },
  "include": ["src/**/*.ts"]
}

Step 4: Create esbuild.config.mjs

Follow Logfire's pattern (no native modules needed, simpler than Logfire):

import esbuild from "esbuild";
import process from "process";
import builtins from "builtin-modules";

const prod = process.argv[2] === "production";

const context = await esbuild.context({
  entryPoints: ["src/main.ts"],
  bundle: true,
  external: [
    "obsidian",
    "electron",
    "@codemirror/autocomplete",
    "@codemirror/collab",
    "@codemirror/commands",
    "@codemirror/language",
    "@codemirror/lint",
    "@codemirror/search",
    "@codemirror/state",
    "@codemirror/view",
    "@lezer/common",
    "@lezer/highlight",
    "@lezer/lr",
    ...builtins,
  ],
  format: "cjs",
  target: "es2022",
  logLevel: "info",
  sourcemap: prod ? false : "inline",
  treeShaking: true,
  outfile: "main.js",
  minify: prod,
});

if (prod) {
  await context.rebuild();
  process.exit(0);
} else {
  await context.watch();
}

Step 5: Create .gitignore

node_modules/
main.js
*.js.map

Step 6: Install dependencies

Run: npm install Expected: node_modules/ created, no errors.

Step 7: Verify build works

Create a minimal src/main.ts:

import { Plugin } from 'obsidian';

export default class FormfirePlugin extends Plugin {
  async onload(): Promise<void> {
    console.log('[Formfire] Loading plugin...');
  }
  onunload(): void {
    console.log('[Formfire] Unloading plugin.');
  }
}

Run: npm run build Expected: main.js created, no errors.

Step 8: Commit

git add package.json manifest.json tsconfig.json esbuild.config.mjs .gitignore src/main.ts
git commit -m "feat: scaffold Formfire plugin project"

Task 2: Type Definitions

Files:

Create: src/types.ts

Step 1: Write all type definitions

// ---------------------------------------------------------------------------
// Field Types
// ---------------------------------------------------------------------------

export type FieldType =
  | 'text'
  | 'textarea'
  | 'number'
  | 'toggle'
  | 'date'
  | 'dropdown'
  | 'tags'
  | 'note-link'
  | 'folder-picker'
  | 'rating';

export interface FormField {
  id: string;
  label: string;
  type: FieldType;
  required: boolean;
  defaultValue?: string | number | boolean | string[];
  placeholder?: string;
  /** For dropdown: list of options. For tags: suggested tags. */
  options?: string[];
  /** For note-link: restrict to files in this folder. */
  folder?: string;
}

// ---------------------------------------------------------------------------
// Form Definition
// ---------------------------------------------------------------------------

export interface FormDefinition {
  id: string;
  name: string;
  icon: string;
  mode: 'create' | 'update';

  // mode: "create" only
  targetFolder?: string;
  fileNameTemplate?: string;
  bodyTemplate?: string;

  // mode: "update" only
  targetFile?: 'active' | 'prompt';

  fields: FormField[];
}

// ---------------------------------------------------------------------------
// Settings
// ---------------------------------------------------------------------------

export interface FormfireSettings {
  forms: FormDefinition[];
}

export const DEFAULT_SETTINGS: FormfireSettings = {
  forms: [],
};

// ---------------------------------------------------------------------------
// Utilities
// ---------------------------------------------------------------------------

/** Recursively merge source into target. Arrays are replaced, not merged. */
export function deepMerge<T extends Record<string, unknown>>(
  target: T,
  source: Partial<T>,
): T {
  const result = { ...target };
  for (const key of Object.keys(source) as (keyof T)[]) {
    const srcVal = source[key];
    const tgtVal = target[key];
    if (
      srcVal !== null &&
      typeof srcVal === 'object' &&
      !Array.isArray(srcVal) &&
      tgtVal !== null &&
      typeof tgtVal === 'object' &&
      !Array.isArray(tgtVal)
    ) {
      result[key] = deepMerge(
        tgtVal as Record<string, unknown>,
        srcVal as Record<string, unknown>,
      ) as T[keyof T];
    } else if (srcVal !== undefined) {
      result[key] = srcVal as T[keyof T];
    }
  }
  return result;
}

Step 2: Verify it compiles

Run: npx tsc --noEmit Expected: No errors.

Step 3: Commit

git add src/types.ts
git commit -m "feat: add type definitions (FormDefinition, FormField, settings)"

Task 3: Template Engine

Files:

Create: src/utils/template-engine.ts

Step 1: Write template engine

/**
 * Simple {{variable}} substitution engine.
 * Built-in variables: {{date}}, {{time}}, {{datetime}}.
 * All other {{keys}} are resolved from the provided values map.
 */
export function renderTemplate(
  template: string,
  values: Record<string, string>,
): string {
  const now = new Date();
  const builtins: Record<string, string> = {
    date: now.toISOString().slice(0, 10),
    time: now.toTimeString().slice(0, 5),
    datetime: `${now.toISOString().slice(0, 10)} ${now.toTimeString().slice(0, 5)}`,
  };

  const allValues = { ...builtins, ...values };

  return template.replace(/\{\{(\w[\w-]*)\}\}/g, (match, key: string) => {
    return allValues[key] ?? match;
  });
}

/**
 * Sanitize a string for use as a file name.
 * Removes characters illegal on Windows/macOS/Linux.
 */
export function sanitizeFileName(name: string): string {
  return name
    .replace(/[\\/:*?"<>|]/g, '-')
    .replace(/\s+/g, ' ')
    .trim();
}

Step 2: Verify it compiles

Run: npx tsc --noEmit Expected: No errors.

Step 3: Commit

git add src/utils/template-engine.ts
git commit -m "feat: add template engine with {{variable}} substitution"

Task 4: Validators

Files:

Create: src/utils/validators.ts

Step 1: Write validator

import { FormField } from '../types';

export interface ValidationError {
  fieldId: string;
  message: string;
}

/**
 * Validate form values against field definitions.
 * Returns an empty array if everything is valid.
 */
export function validateForm(
  fields: FormField[],
  values: Record<string, unknown>,
): ValidationError[] {
  const errors: ValidationError[] = [];

  for (const field of fields) {
    const value = values[field.id];

    if (field.required) {
      if (value === undefined || value === null || value === '') {
        errors.push({ fieldId: field.id, message: `${field.label} is required.` });
        continue;
      }
      if (Array.isArray(value) && value.length === 0) {
        errors.push({ fieldId: field.id, message: `${field.label} is required.` });
        continue;
      }
    }

    if (value !== undefined && value !== null && value !== '') {
      if (field.type === 'number' && typeof value === 'string') {
        if (isNaN(Number(value))) {
          errors.push({ fieldId: field.id, message: `${field.label} must be a number.` });
        }
      }
      if (field.type === 'rating') {
        const n = Number(value);
        if (isNaN(n) || n < 1 || n > 5) {
          errors.push({ fieldId: field.id, message: `${field.label} must be between 1 and 5.` });
        }
      }
    }
  }

  return errors;
}

Step 2: Verify it compiles

Run: npx tsc --noEmit Expected: No errors.

Step 3: Commit

git add src/utils/validators.ts
git commit -m "feat: add form field validators"

Task 5: FormStore (CRUD for Form Definitions)

Files:

Create: src/core/form-store.ts

Step 1: Write FormStore

import { FormDefinition, FormfireSettings } from '../types';

/**
 * Manages CRUD operations on FormDefinitions within plugin settings.
 * Does NOT persist — the caller (plugin) calls saveSettings() after mutations.
 */
export class FormStore {
  constructor(private settings: FormfireSettings) {}

  getAll(): FormDefinition[] {
    return this.settings.forms;
  }

  getById(id: string): FormDefinition | undefined {
    return this.settings.forms.find(f => f.id === id);
  }

  getByName(name: string): FormDefinition | undefined {
    return this.settings.forms.find(
      f => f.name.toLowerCase() === name.toLowerCase(),
    );
  }

  add(form: FormDefinition): void {
    this.settings.forms.push(form);
  }

  update(id: string, patch: Partial<FormDefinition>): void {
    const idx = this.settings.forms.findIndex(f => f.id === id);
    if (idx === -1) return;
    this.settings.forms[idx] = { ...this.settings.forms[idx], ...patch };
  }

  remove(id: string): void {
    this.settings.forms = this.settings.forms.filter(f => f.id !== id);
  }

  duplicate(id: string): FormDefinition | undefined {
    const original = this.getById(id);
    if (!original) return undefined;
    const copy: FormDefinition = {
      ...structuredClone(original),
      id: crypto.randomUUID(),
      name: `${original.name} (Copy)`,
    };
    this.settings.forms.push(copy);
    return copy;
  }

  /** Move a form up or down in the list. */
  reorder(id: string, direction: 'up' | 'down'): void {
    const idx = this.settings.forms.findIndex(f => f.id === id);
    if (idx === -1) return;
    const swap = direction === 'up' ? idx - 1 : idx + 1;
    if (swap < 0 || swap >= this.settings.forms.length) return;
    [this.settings.forms[idx], this.settings.forms[swap]] =
      [this.settings.forms[swap], this.settings.forms[idx]];
  }

  /** Create a blank FormDefinition with sensible defaults. */
  createBlank(): FormDefinition {
    return {
      id: crypto.randomUUID(),
      name: 'New Form',
      icon: 'file-input',
      mode: 'create',
      targetFolder: '/',
      fileNameTemplate: '{{date}}-{{title}}',
      bodyTemplate: '',
      fields: [],
    };
  }
}

Step 2: Verify it compiles

Run: npx tsc --noEmit Expected: No errors.

Step 3: Commit

git add src/core/form-store.ts
git commit -m "feat: add FormStore for CRUD on form definitions"

Task 6: FormProcessor (Note Creation & Frontmatter Update)

Files:

Create: src/core/form-processor.ts

Step 1: Write FormProcessor

        for (const ft of FIELD_TYPES) {
          d.addOption(ft.value, ft.label);
        }
        d.setValue(field.type)
          .onChange(v => {
            field.type = v as FieldType;
            this.render();
          });
      });

    new Setting(fieldEl)
      .setName('Required')
      .addToggle(t => t
        .setValue(field.required)
        .onChange(v => { field.required = v; }));

    // Type-specific settings
    if (field.type === 'dropdown' || field.type === 'tags') {
      new Setting(fieldEl)
        .setName('Options')
        .setDesc('Comma-separated list')
        .addText(t => t
          .setValue((field.options ?? []).join(', '))
          .setPlaceholder('Option A, Option B, Option C')
          .onChange(v => {
            field.options = v.split(',').map(s => s.trim()).filter(Boolean);
          }));
    }

    if (field.type === 'note-link') {
      new Setting(fieldEl)
        .setName('Restrict to folder')
        .addText(t => t
          .setValue(field.folder ?? '')
          .setPlaceholder('Leave empty for all notes')
          .onChange(v => { field.folder = v || undefined; }));
    }

    new Setting(fieldEl)
      .setName('Placeholder')
      .addText(t => t
        .setValue(field.placeholder ?? '')
        .onChange(v => { field.placeholder = v || undefined; }));
  }

  onClose(): void {
    this.contentEl.empty();
  }
}

Step 2: Write settings-tab.ts

import { App, PluginSettingTab, Setting } from 'obsidian';
import type FormfirePlugin from '../main';
import { FormBuilderModal } from './form-builder';

export class FormfireSettingTab extends PluginSettingTab {
  constructor(app: App, private plugin: FormfirePlugin) {
    super(app, plugin);
  }

  display(): void {
    const { containerEl } = this;
    containerEl.empty();

    containerEl.createEl('h1', { text: 'Formfire' });
    containerEl.createEl('p', {
      text: 'Create forms for structured data input. Forms can create new notes or update existing frontmatter.',
      cls: 'setting-item-description',
    });

    // Form list
    const forms = this.plugin.formStore.getAll();

    if (forms.length === 0) {
      containerEl.createDiv({
        cls: 'ff-settings-empty',
        text: 'No forms yet. Click the button below to create one.',
      });
    }

    for (const form of forms) {
      new Setting(containerEl)
        .setName(form.name)
        .setDesc(`${form.mode === 'create' ? 'Creates new note' : 'Updates frontmatter'} \u2022 ${form.fields.length} field(s)`)
        .addButton(btn => btn
          .setButtonText('Edit')
          .onClick(() => {
            new FormBuilderModal(this.app, form, async (updated) => {
              this.plugin.formStore.update(form.id, updated);
              await this.plugin.saveSettings();
              this.plugin.refreshCommands();
              this.display();
            }).open();
          }))
        .addButton(btn => btn
          .setButtonText('Duplicate')
          .onClick(async () => {
            this.plugin.formStore.duplicate(form.id);
            await this.plugin.saveSettings();
            this.plugin.refreshCommands();
            this.display();
          }))
        .addButton(btn => btn
          .setButtonText('Delete')
          .setWarning()
          .onClick(async () => {
            this.plugin.formStore.remove(form.id);
            await this.plugin.saveSettings();
            this.plugin.refreshCommands();
            this.display();
          }));
    }

    // Add form button
    new Setting(containerEl)
      .addButton(btn => btn
        .setButtonText('+ New Form')
        .setCta()
        .onClick(() => {
          const blank = this.plugin.formStore.createBlank();
          new FormBuilderModal(this.app, blank, async (created) => {
            this.plugin.formStore.add(created);
            await this.plugin.saveSettings();
            this.plugin.refreshCommands();
            this.display();
          }).open();
        }));
  }
}

Step 3: Verify it compiles

Run: npx tsc --noEmit Expected: May error on FormfirePlugin references — that's fine, wired up in Task 12.

Step 4: Commit

git add src/ui/settings-tab.ts src/ui/form-builder.ts
git commit -m "feat: add settings tab with visual form builder"

Task 12: Wire Everything in main.ts

Files:

Modify: src/main.ts

This is the final wiring task. Replace the minimal main.ts with the full plugin class.

Step 1: Write the complete main.ts

import { Plugin, Notice, WorkspaceLeaf } from 'obsidian';
import { FormfireSettings, DEFAULT_SETTINGS, deepMerge } from './types';
import { FormStore } from './core/form-store';
import { FormModal } from './ui/form-modal';
import { FormPickerModal } from './ui/form-picker-modal';
import { FormfireSettingTab } from './ui/settings-tab';
import { FormSidebarView, FORM_SIDEBAR_VIEW_TYPE } from './ui/form-sidebar';

export default class FormfirePlugin extends Plugin {
  settings!: FormfireSettings;
  formStore!: FormStore;

  private dynamicCommandIds: string[] = [];

  async onload(): Promise<void> {
    console.log('[Formfire] Loading plugin...');

    await this.loadSettings();
    this.formStore = new FormStore(this.settings);

    // Settings tab
    this.addSettingTab(new FormfireSettingTab(this.app, this));

    // Sidebar view
    this.registerView(
      FORM_SIDEBAR_VIEW_TYPE,
      (leaf) => new FormSidebarView(leaf, this),
    );

    // Ribbon icon
    this.addRibbonIcon('file-input', 'Formfire: Open form', () => {
      this.openFormPicker();
    });

    // Static commands
    this.addCommand({
      id: 'open-form',
      name: 'Open form',
      callback: () => this.openFormPicker(),
    });

    this.addCommand({
      id: 'open-sidebar',
      name: 'Open sidebar',
      callback: () => this.activateSidebar(),
    });

    // Dynamic per-form commands
    this.registerDynamicCommands();
  }

  onunload(): void {
    console.log('[Formfire] Unloading plugin.');
  }

  async loadSettings(): Promise<void> {
    const saved = (await this.loadData()) as Partial<FormfireSettings> | null;
    this.settings = deepMerge(DEFAULT_SETTINGS, saved ?? {});
  }

  async saveSettings(): Promise<void> {
    await this.saveData(this.settings);
    this.refreshSidebar();
  }

  /** Open the form picker, then the chosen form. */
  openFormPicker(): void {
    const forms = this.formStore.getAll();
    if (forms.length === 0) {
      new Notice('No forms defined. Open Formfire settings to create one.');
      return;
    }
    if (forms.length === 1) {
      this.openForm(forms[0].id);
      return;
    }
    new FormPickerModal(this.app, forms, (form) => {
      this.openForm(form.id);
    }).open();
  }

  /** Open a specific form by ID. */
  openForm(formId: string): void {
    const form = this.formStore.getById(formId);
    if (!form) {
      new Notice('Form not found.');
      return;
    }
    new FormModal(this.app, form).open();
  }

  /** Register a command for each form for direct access. */
  registerDynamicCommands(): void {
    for (const form of this.formStore.getAll()) {
      const commandId = `open-form-${form.id}`;
      this.addCommand({
        id: commandId,
        name: `Open form: ${form.name}`,
        callback: () => this.openForm(form.id),
      });
      this.dynamicCommandIds.push(commandId);
    }
  }

  /** Called after form CRUD to re-register commands. */
  refreshCommands(): void {
    // Obsidian doesn't support removing commands at runtime.
    // New commands are registered on next plugin reload.
    // Removed forms' commands become no-ops (form not found).
  }

  /** Activate or reveal the sidebar view. */
  async activateSidebar(): Promise<void> {
    const existing = this.app.workspace.getLeavesOfType(FORM_SIDEBAR_VIEW_TYPE);
    if (existing.length > 0) {
      this.app.workspace.revealLeaf(existing[0]);
      return;
    }
    const leaf = this.app.workspace.getRightLeaf(false);
    if (leaf) {
      await leaf.setViewState({ type: FORM_SIDEBAR_VIEW_TYPE, active: true });
      this.app.workspace.revealLeaf(leaf);
    }
  }

  /** Re-render sidebar if it's open. */
  private refreshSidebar(): void {
    const leaves = this.app.workspace.getLeavesOfType(FORM_SIDEBAR_VIEW_TYPE);
    for (const leaf of leaves) {
      const view = leaf.view;
      if (view instanceof FormSidebarView) {
        view.render();
      }
    }
  }
}

Step 2: Verify full build

Run: npm run build Expected: main.js created, no errors.

Step 3: Commit

git add src/main.ts
git commit -m "feat: wire up main plugin with commands, sidebar, settings"

Task 13: Styles

Files:

Create: styles.css

Use the frontend-design skill for polished, production-grade CSS. The CSS must cover these class selectors (all prefixed ff-):

Form fields: .ff-field, .ff-field-label, .ff-field-required, .ff-field-control, .ff-field-error, .ff-input, .ff-textarea, .ff-dropdown

Tags field: .ff-tags-container, .ff-tag-chip, .ff-tag-remove, .ff-tags-input

Autocomplete: .ff-suggest-list, .ff-suggest-item

Rating: .ff-rating, .ff-star, .ff-star-active

Form modal: .ff-form-modal, .ff-fields, .ff-form-footer

Form builder: .ff-builder-modal, .ff-builder-fields, .ff-builder-field, .ff-builder-field-header, .ff-builder-field-actions, .ff-builder-action-btn, .ff-builder-delete, .ff-builder-add-btn, .ff-builder-footer, .ff-builder-textarea, .ff-builder-field-num

Sidebar: .ff-sidebar, .ff-sidebar-header, .ff-sidebar-settings, .ff-sidebar-list, .ff-sidebar-item, .ff-sidebar-badge, .ff-badge-create, .ff-badge-update, .ff-sidebar-name, .ff-sidebar-empty

Settings: .ff-settings-empty

All colors must use Obsidian CSS variables (--background-primary, --text-normal, --interactive-accent, --background-modifier-border, --text-muted, --text-faint, --text-error, --background-modifier-hover, --background-secondary).

Step 1: Invoke frontend-design skill to create styles.css

Step 2: Verify build with styles

Run: npm run build Expected: No errors. styles.css is picked up by Obsidian directly (not bundled by esbuild).

Step 3: Commit

git add styles.css
git commit -m "feat: add Formfire styles"

Task 14: Manual Integration Test

No code to write. This is a verification task.

Step 1: Install plugin in Obsidian vault

Copy main.js, manifest.json, and styles.css to .obsidian/plugins/formfire/ in a test vault.

Step 2: Enable plugin

Open Obsidian -> Settings -> Community Plugins -> Enable Formfire.

Step 3: Test form creation flow

Open Formfire settings
Click "+ New Form"
Set name: "Meeting Note"
Mode: Create
Target folder: "meetings"
File name template: {{date}}-{{title}}
Add fields: title (text, required), date (date), attendees (tags), status (dropdown: planned/done/cancelled), notes (textarea)
Body template: # {{title}}\n\n## Attendees\n{{attendees}}\n\n## Notes\n
Save

Step 4: Test form submission

Open command palette -> "Formfire: Open form: Meeting Note"
Fill out the form
Submit
Verify: new note created in meetings/ with correct frontmatter and body

Step 5: Test update mode

Create a second form "Update Status" with mode: update, targetFile: active
Open a note, run the command
Verify: frontmatter properties updated correctly

Step 6: Test sidebar

Open command palette -> "Formfire: Open sidebar"
Verify: sidebar shows both forms
Click a form -> verify modal opens

Step 7: Commit (if any fixes needed)

git add -A
git commit -m "fix: integration test fixes"
