Evernote Local Dev Loop

Overview

Configure an efficient local development environment for Evernote API integration with sandbox testing, hot reload, ENML helpers, and a local Express server for OAuth testing.

Prerequisites

Completed
```
evernote-install-auth
```
setup
Node.js 18+ or Python 3.10+
Evernote sandbox account at https://sandbox.evernote.com

Instructions

Step 1: Project Structure

Organize your project with clear separation of concerns:

evernote-app/
  src/
    services/       # NoteService, SearchService, etc.
    utils/          # ENML helpers, query builder
    middleware/     # Auth, rate limiting
  test/             # Unit and integration tests
  scripts/          # Dev utilities (test-connection, seed-data)
  .env.development  # Sandbox credentials
  .env.production   # Production credentials (gitignored)

Step 2: Environment Configuration

Create

.env.development

with sandbox credentials. Use a Developer Token for quick iteration (skip OAuth during development). Add

.env*

.gitignore

# .env.development
EVERNOTE_CONSUMER_KEY=your-sandbox-key
EVERNOTE_CONSUMER_SECRET=your-sandbox-secret
EVERNOTE_DEV_TOKEN=your-developer-token
EVERNOTE_SANDBOX=true
NODE_ENV=development
PORT=3000

Step 3: Evernote Client Wrapper

Create a client factory that switches between Developer Token (for scripts and tests) and OAuth (for the web app) based on environment configuration.

function createClient() {
  if (process.env.EVERNOTE_DEV_TOKEN) {
    return new Evernote.Client({
      token: process.env.EVERNOTE_DEV_TOKEN,
      sandbox: true
    });
  }
  return new Evernote.Client({
    consumerKey: process.env.EVERNOTE_CONSUMER_KEY,
    consumerSecret: process.env.EVERNOTE_CONSUMER_SECRET,
    sandbox: process.env.EVERNOTE_SANDBOX === 'true'
  });
}

Step 4: ENML Utility Helpers

Build helper functions:

wrapInENML(html)

textToENML(text)

htmlToENML(html)

(strip forbidden elements), and

validateENML(content)

. These prevent

BAD_DATA_FORMAT

errors during development.

Step 5: Express Server with OAuth

Set up a local Express server with session management for OAuth flow testing. Include routes for

/auth/start

(get request token),

/auth/callback

(exchange for access token), and

/dashboard

(authenticated operations).

Step 6: Quick Test Script

Create a

scripts/test-connection.js

that verifies SDK setup by calling

userStore.getUser()

and

noteStore.listNotebooks()

. Run with

node scripts/test-connection.js

For the full project setup, Express server, ENML utilities, and test scripts, see Implementation Guide.

Output

Project structure with services, utils, and middleware directories
Environment configuration for sandbox and production
Client factory with Developer Token and OAuth support
ENML utility library (wrap, convert, validate)
Express server with OAuth flow for local testing
Connection test script for quick verification

Error Handling

Error	Cause	Solution
`EVERNOTE_DEV_TOKEN not set`	Missing dev token	Get from `sandbox.evernote.com/api/DeveloperToken.action`
`Invalid consumer key`	Wrong sandbox vs production key	Verify `EVERNOTE_SANDBOX` matches your key type
`Session undefined`	Missing express-session middleware	Install and configure `express-session`
Port already in use	Another process on port 3000	Change `PORT` in `.env` or kill the process

Examples

Quick sandbox test: Set

EVERNOTE_DEV_TOKEN

, run

node scripts/test-connection.js

to verify authentication, then create a test note using the Developer Token shortcut.

Full OAuth loop: Start the Express server, navigate to

http://localhost:3000/auth/start

, complete the Evernote authorization, and verify the access token is stored in the session.
