Devographics Monorepo

This is the codebase that runs the Devographics surveys, such as State of JS and State of CSS.

Setup

1. Install pnpm

This monorepo uses pnpm, and you should start by installing it.

2. Clone Repositories

A. Install Script

You can clone all repositories in the right place and create blank .env files with the following install script:

curl -o- https://raw.githubusercontent.com/Devographics/Monorepo/main/install.sh | bash

B. Manual Install

Monorepo

• Clone this monorepo locally with git clone https://github.com/Devographics/Monorepo.git

Other repos

The survey apps rely on a lot of metadata. If you need to load or modify this metadata from your local filesystem instead of through our API, you can optionally also clone these other repos:

1. entities: the YAML files containing all metadata for the features, sites, people, libraries, etc. mentioned in the surveys.
2. surveys: contains the YAML files that define survey configs and outlines.
3. locale-en-US: (or any other locale) contains the locale strings used in the survey.

I suggest using the following file structure:

• devographics parent directory
  • devographics/monorepo
    • devographics/monorepo/surveyform
    • devographics/monorepo/results
    • devographics/monorepo/...
  • devographics/entities
  • devographics/surveys
  • devographics/locales
    • devographics/locales/locale-en-US
    • devographics/locales/locale-fr-FR
    • devographics/locales/...

3. Install Dependencies

Whenever you need to run a project in the monorepo directory (such as results, surveyform, etc.), you will need to first run pnpm install from within its subdirectory.

• cd monorepo
• pnpm install

This will install dependencies for all applications of the monorepository.

4. Running a Project

You can run each project with pnpm run dev when inside its subdirectory.

For example, for the surveyform app:

• cd monorepo
• cd surveyform
• pnpm run dev

If this is your first time running a project, you will run into some issues that need to be fixed by configuring your local environment variables (see below).

Remote vs Local API

You can run the results and surveyform project by connecting to our remote production API (https://api.devographics.com/graphql).

Alternatively, if you want to use local files for the surveys, locales, etc. you will need to run a local copy of the API project (monorepo/api) locally as well to load them. Once the API is running, you can then point the other apps to it via the API_URL env variable.

Note that even when the API is running locally, you will still need internet access to connect to the databases and load image assets.

5. Environment Variables Setup

Each app within monorepo needs its own environment variables defined inside a .env files (except for surveyform and surveyadmin, which use a .env.development.local file).

Here are some ways that can help with this setup:

1. You can use the .env.example file in each project subdirectory (such as this one for the surveyform project) as a starting point by pasting its contents into your own .env or .env.development.local (for Next.js projects such as surveyform) file.
2. You will need credentials to connect to our MongoDB and Redis staging database. You can ask me (Sacha) on Discord and I will provide them.
3. When running the app with pnpm run dev you will get error messages indicating any remaining missing environment variables.

You can also refer to variables.yml directly and look for variables corresponding to the current app (e.g. results).

Apps

The following apps are all contained within the monorepo.

📡 API

Node.js TypeScript app.

What It Does

• Make the outlines of each survey available to the survey form app.
• Connect to the database and generate the data for the results app's charts.
• Provide the internationalisation strings for each locale.

Code

• https://github.com/Devographics/Monorepo/tree/main/api

Hosted On

• https://render.com

🔍 GraphiQL

GraphQL IDE

What It Does

• Make it easier to test and query the API.

Code

• https://github.com/Devographics/Monorepo/tree/main/graphiql

Hosted On

• https://netlify.com

Domain

• https://api.devographics.com

✍️ Surveyform

Next.js TypeScript app.

What It Does

• Let respondents take the survey.

Code

• https://github.com/Devographics/Monorepo/tree/main/surveyform

Hosted On

• https://vercel.com

Domain

• https://survey.devographics.com

📊 Results

Gatsby TypeScript app.

What It Does

• Display the survey results.

Code

• https://github.com/Devographics/Monorepo/tree/main/results

Hosted On

• https://netlify.com

Domains

• https://2022.stateofjs.com
• https://2023.stateofcss.com
• etc.

🔒 Surveyadmin

Admin app.

What It Does

• Provide a dashboard to manage all surveys.
• Handle data processing and normalization.

Hosted On

• Only running locally for now.

---

Databases

🗂️ Main Database

MongoDB database.

What It Does

• Store the raw data entered by respondents.
• Store the "normalized" data once it's been processed.

Hosted On

• https://www.mongodb.com/atlas/database

Local dev

You can plug to a staging database or run Mongo locally via Docker.

See "docker-compose.yml" and "Justfile" for our local setup. When running locally, data are stored in a ".mongo" folder in the monorepo folder. You can delete this folder to reset the local database.

💾 Cache Database

Redis database.

What It Does

• Cache the results of queries made to the API app.

Hosted On

• https://upstash.com/

Local dev

You can plug to a staging database or run Redis locally.

Since we use Upstash, which rely on HTTP requests instead of direct Redis connection, we also setup an HTTP proxy.

See "docker-compose.yml" and "Justfile" for our local setup.

To reset the local Redis instance, the best approach is to remove the Redis container.
