WebCalibre2 | Certificates & secrets

-

Since you are using NextAuth.js, the URL must follow a very specific pattern.

-

For local development: http://localhost:3000/api/auth/callback/azure-ad

-

For production: https://your-domain.com/api/auth/callback/azure-ad

-

Note: Replace azure-ad with whatever ID you give the provider in your code. By default, in NextAuth, it is usually azure-ad.

3.1. Permissions Needed

Permissions Needed

-

4. Steps

-

4.1. create nextjs app

-

The following command creates the nextjs folder structure

-

Yes, Next.js has a specific syntax to create a project in your current directory instead of creating a new subfolder.

-

To do this, navigate to your empty project folder in the terminal and run:

-

-npx create-next-app@latest .
-
-

Important Details:

-
    -
  1. -

    The Dot (.): This tells the installer to use the current directory as the project root.

    -
    2. -
  2. -

    Naming Conflict: If the folder name contains capital letters (e.g., WebCalibre), the command will fail with an error. Next.js requires the root folder name to be all lowercase and URL-friendly. You must rename your folder to web-calibre before running the command. -This caused me rename to all lower case.

    -
    3. -
-

3.Empty Folder: The directory must be empty (except for hidden files like .git). If you already have files in there, the installer will stop to prevent overwriting your work.

-

What happens next? -Even though you are using the current directory, the interactive prompt will still ask you:

-

"What is your project named?" You can just hit Enter to accept the current folder name.

-

Configuration: It will then ask you about TypeScript, ESLint, Tailwind CSS, the src/ directory, and the App Router.

-

Based on our previous discussions, I recommend selecting "Yes" for TypeScript, ESLint, Tailwind, the src/ directory, and the App Router to match the professional structure we planned for WebCalibre.

-

4.2. Create .env file

-

In Next.js, the distinction between .env and .env.local is primarily about security and overriding defaults. -While both store key-value pairs, they are handled differently by Git and the Next.js runtime.

-
    -
  1. Security & Version Control (Git)The most important reason is that .env.local is automatically ignored by Git in standard Next.js projects.
    2. -
- -
    -
  1. Priority & Overriding -Next.js uses a "hierarchy" of loading.1 If you define the same variable in both files, .env.local wins. -This allows you to set a generic placeholder in .env for the team, but use your specific local developer settings on your own machine. -For example:
    2. -
- -

The Next.js Loading Order -Next.js looks for variables in this specific order (from highest priority to lowest):

-
    -
  1. process.env (System environment variables)
    2. -
  2. .env.development.local (Only during npm run dev)
    3. -
  3. .env.local (Available in all environments except test)
    4. -
  4. .env.development
    5. -
  5. .env (The final fallback)
    6. -
-
DATABASE_URL="postgresql://stephen:Web2025$$@192.168.1.210:5432/webcalibre2"
-
-# Credentials for your Microsoft App (NextAuth)
-AZURE_AD_CLIENT_ID="549931a-f491-436b-b7bc-d37d8ca3c17e"
-AZURE_AD_CLIENT_SECRET="6a242be1-c711-4cc3-a132-03c1f57993ed"
-AZURE_AD_TENANT_ID="1c06ce7c-7884-4796-8652-d4c32d75a5d0"

Summary Comparison Table

Feature.env.env.local
PurposeShared defaults/constantsPrivate secrets & local overrides
Committed to Git?YesNo (Added to .gitignore)
Sensitive Data?NEVERYES (API Keys, Secrets)
ScopeAll developers/environmentsJust your machine
-

**Best Practice Tip: ** Since .env.local isn't shared on GitHub, it’s a good idea to create a file named .env.example in your project. This file should contain the names of the keys (e.g., AZURE_AD_CLIENT_SECRET=) but leave the values blank, so other developers know which variables they need to create on their own machines.

-

4.3. Configure Git

-

Nextjs initializes git by default. But is doesn't add some configs that I do

-

git config --global push.followTags true

-

git remote add origin "/Users/stephenlohning/Library/CloudStorage/OneDrive-Personal/Documents/10_GIT_Repositories/124_WebCalibre2.git"

-

git remote -v -origin /Users/stephenlohning/Library/CloudStorage/OneDrive-Personal/Documents/10_GIT_Repositories/124_WebCalibre2.git (fetch) -origin /Users/stephenlohning/Library/CloudStorage/OneDrive-Personal/Documents/10_GIT_Repositories/124_WebCalibre2.git (push)

-

4.4. Test nextjs

-
npm run dev
-
-> 124_webcalibre2@0.1.0 dev
-> next dev
-
-▲ Next.js 16.1.1 (Turbopack)
-- Local:         http://localhost:3000
-- Network:       http://192.168.1.100:3000
-- Environments: .env
-
-✓ Starting...
-✓ Ready in 648ms
-
-

If it working proceed

-

4.5. Check Authentication

-

I ran through the Video:-

-

Next.js Authentication Made Easy with Microsoft Entra ID

-

4.6. Install NextAuth.js v5

-

npm install next-auth@beta

-

Setup Environment -The only environment variable that is mandatory is the AUTH_SECRET. This is a random value used by the library to encrypt tokens and email verification hashes. (See Deployment to learn more). You can generate one via the official Auth.js CLI running:

-

npx auth secret

-

created .env.local

-
AUTH_SECRET="7cz3Z4kUI2kB3mdAPo58iioUDLSRJ92X8+boEixvO8k=" # Added by `npx auth`. Read more: https://cli.authjs.dev
-
-

5. .env files

-

5.1. .env.local

-
# values generated by Gemini
-# Generated for security
-AUTH_SECRET="7cz3Z4kUI2kB3mdAPo58iioUDLSRJ92X8+boEixvO8k="
-
-# Use 'common' for multi-tenant (Work + Personal) support
-AUTH_MICROSOFT_ENTRA_ID_TENANT_ID="common"
-
-# The Application (client) ID
-AUTH_MICROSOFT_ENTRA_ID_ID="b549931a-f491-436b-b7bc-d37d8ca3c17e"
-
-# The Client Secret VALUE (ensure no leading '6' or spaces)

6. Prisma Install

-

To get Prisma fully installed and ready to talk to your PostgreSQL database, you need to install the CLI (for migrations) and the Client (for your code to query the database).

-

Run these three commands in your terminal:

-
    -
  1. Install the Prisma packages -Bash
    2. -
-

6.1. The CLI is for development tasks like migrations

-

npm install prisma --save-dev

-

##The Client is used by your Next.js code to talk to the DB

-
npm install @prisma/client
-
-
    -
  1. Install the Dotenv helper -Since you are keeping your DATABASE_URL in .env.local (and your password has special characters), you need this to bridge the gap between Next.js and the Prisma CLI:
    2. -
-

-npm install dotenv-cli --save-dev
-
-
    -
  1. Initialize and Generate -Once the packages are installed, you need to initialize the Prisma folder (if you haven't already) and generate the types for your FileNode model:
    2. -
-

Bash

-

6.2. Create the prisma folder

-
npx prisma init
-
-

7. Run this whenever you change your schema.prisma file

-

npx dotenv -e .env.local -- npx prisma generate -4. Apply your Schema to PostgreSQL -Finally, run this to actually create the tables in your webcalibre2 database:

-

npx dotenv -e .env.local -- npx prisma migrate dev --name init_database

-

7.1. Pro-Tip: Update your package.json

-

To avoid typing that long dotenv command every time, open your package.json and add this to the "scripts" section:

-

JSON

-

"scripts": { -"db:migrate": "dotenv -e .env.local -- prisma migrate dev", -"db:studio": "dotenv -e .env.local -- prisma studio" -} -Now, you can just run npm run db:migrate whenever you update your schema!

-

8. Where we are up to 8/1/2026

-

We can authenticate with MS Azure, upload a file and store it on my personal OneDrive. -I can see a few problems,

-
    -
  1. -

    if the file gets stored with its original filename, if I store the same file again it tells that it fail, but in reality it did not fail the it got renamed with 1.pdf added this is not added data base.

    -
    2. -
  2. -

    We may be better to create a folder and put the file in the folder, to me the logical name would id of the file, but that is automatically create and assigned when the data is stored as a UUID.

    -
    3. -
  3. -

    We would have to create the UUID ourselves, so that we can create a folder with that specific UUID and store the file in the folder.

    -
    4. -
  4. -

    The Upload file Page needs to be able to create folder as well select a parent , add a description of either the file

    -
    5. -
-

9. Testing Creating And Uploading Folders and Files

-

The functionality works may not the best user interface

-

Projects ID 0371fdfe-a2d1-4f25-b229-804f299bc064 -Project-1 ID c8eebe0e-6e90-4cfb-8e44-c05f7064f3b1 parentID 0371fdfe-a2d1-4f25-b229-804f299bc064 -AS-NZS3000-2018.pdf parentID c8eebe0e-6e90-4cfb-8e44-c05f7064f3b1

-

Now we will go now and add metadata

-

Now we have the metadata along with some great filters on the data board page

-

Now we are going to implement an an update of a file or folder stored. 12/1/2026

-

For download there 2 function we need to implement

-
    -
  1. -

    down load the file to ~/user/Downloads, this should work for any file type including pdf

    -
    2. -
  2. -

    if the file is a pdf open the file in another tab in the browser as most browser support reading a pdf

    -
    3. -
-

    -
    3. -
-

So we need to implement 2 new actions, downLoad file and open pdf to read. Does this make sense ?

Where the code should exist

-

Two questions

-
    -
  1. should the -// 2. Fetch the content from Microsoft Graph -const response = await fetch( -https://graph.microsoft.com/v1.0/me/drive/items/${node.oneDriveId}/content, -{ -headers: { -'Authorization': Bearer ${token}, -'Accept': '/' -}, -} -); -Should this be in the services/onedrive.ts to be compliant with the Data Access Layer (DAL) that nextjs recomments?
    2. -
  2. where should this getMetadataFromJson(buffer: Buffer)  get placed , I think it should be placed in lib/metadata-extractor and exported from there, what do you think?
    3. -
-

Those are excellent architectural questions. You're moving from "making it work" to "making it scale," which is exactly where you want to be.

-

1. Where to put the fetch call?

-

Yes, it absolutely belongs in services/onedrive.ts.

-

Next.js (and general clean architecture) recommends a Data Access Layer (DAL) to decouple your business logic from the specific implementation of your data source.

-

Why this is better:

- -

Recommended structure for services/onedrive.ts:

-
export async function getOneDriveFileBuffer(oneDriveId: string, token: string): Promise<Buffer> {
-  const response = await fetch(
-    `https://graph.microsoft.com/v1.0/me/drive/items/${oneDriveId}/content`,
-    {
-      headers: { 
-        'Authorization': `Bearer ${token}`,
-        'Accept': '*/*' 
-      },
-    }
-  );
-
-  if (!response.ok) {
-    throw new Error(`OneDrive download failed: ${response.statusText}`);
-  }
-
-  const arrayBuffer = await response.arrayBuffer();
-  return Buffer.from(arrayBuffer);
-}
-
-
-
-

2. Where to put getMetadataFromJson?

-

lib/metadata-extractor.ts is the perfect spot.

-

In the Next.js ecosystem, the lib/ directory is the standard convention for "Internal Libraries" or "Utilities"—code that is purely functional, doesn't depend on React, and performs a specific technical task (like parsing a buffer).

-

Why this is the right move:

- -

Structure for lib/metadata-extractor.ts:

-
import exifReader from 'exif-reader';
-
-// Define an interface for your metadata to keep your Json field typed
-export interface FileMetadata {
-  deviceModel?: string;
-  capturedAt?: Date;
-  lat?: number;
-  lng?: number;
-  [key: string]: any; // Allows for other fields
-}
-
-export function extractExifMetadata(buffer: Buffer): FileMetadata {
-  // logic goes here...
-}
-
-
-
-

🏗️ How it looks all together

-

When you put these in their proper places, your API Route or Server Action becomes very readable "glue" code:

-
    -
  1. Get Token (Auth Service)
    2. -
  2. Download Buffer (services/onedrive.ts)
    3. -
  3. Extract Data (lib/metadata-extractor.ts)
    4. -
  4. Save to DB (Prisma / DAL)
    5. -
-

Would you like me to help you refine the internal logic of the extractExifMetadata function to ensure it handles the specific "Rational" numbers (fractions) that EXIF often uses for exposure and GPS?
