TeamMapper

!TeamMapper Screenshot

Mindmapping made simple: Host and create your own mindmaps. Share your mindmap sessions with your team and collaborate on mindmaps.

TeamMapper is based on mindmapp (https://github.com/cedoor/mindmapp , discontinued). In contrast to mindmapp, TeamMapper features shared mindmapping sessions for your team based on websockets. Try it: TeamMapper.org

Features:

• Creation: Host and create your own mindmaps
• Customization: Add images, pictograms\*, colors, font properties and links to nodes
• Collaboration: Share your mindmap with friends and collegues, using either a view-only or modification invite!
• Interoperability: Import and export functionality (JSON, Mermaid, SVG, PDF, PNG...)
• Shareability: Use a QR Code or URL to share your maps
• GDPR Compliancy: By default, mindmaps are deleted after 30 days
• Usability: Redo / Undo, many Shortcuts

Getting started

Quick Start (without building the image)

Prepared docker image: docker pull ghcr.io/b310-digital/teammapper:latest

Docker compose

Attention: Add the missing password for postgres inside app_prod and postgres_prod!

docker compose up -d and visit localhost:80

version: "3.8"
services:
  app_prod:
    image: ghcr.io/b310-digital/teammapper:latest
    environment:
      MODE: PROD
      BINDING: "0.0.0.0"
      POSTGRES_DATABASE: teammapper-db
      POSTGRES_HOST: postgres_prod
      POSTGRES_PASSWORD:
      POSTGRES_PORT: 5432
      POSTGRES_SSL: false
      POSTGRES_SSL_REJECT_UNAUTHORIZED: false
      POSTGRES_USER: teammapper-user
      POSTGRES_QUERY_TIMEOUT: 100000
      POSTGRES_STATEMENT_TIMEOUT: 100000
      DELETE_AFTER_DAYS: 30
      AI_ENABLED: false
    ports:
      - 80:3000
    depends_on:
      - postgres_prod
postgres_prod:
    image: postgres:12-alpine
    # Pass config parameters to the postgres server.
    # Find more information below when you need to generate the ssl-relevant file your self
    # command: -c ssl=on -c ssl_cert_file=/var/lib/postgresql/server.crt -c ssl_key_file=/var/lib/postgresql/server.key
    environment:
      PGDATA: /var/lib/postgresql/data/pgdata
      POSTGRES_DB: teammapper-db
      POSTGRES_PASSWORD:
      POSTGRES_PORT: 5432
      POSTGRES_USER: teammapper-user
    volumes:
      # To setup an ssl-enabled postgres server locally, you need to generate a self-signed ssl certificate.
      # See README.md for more information.
      # Mount the ssl_cert_file and ssl_key_file into the docker container.
      - ./ca/server.crt:/var/lib/postgresql/server.crt
      - ./ca/server.key:/var/lib/postgresql/server.key
      - postgres_prod_data:/var/lib/postgresql/data/pgdata
volumes:
  postgres_prod_data:

Development

• Start up app necessary services

docker compose up -d --build --force-recreate

• Install and build local workspace packages required by the frontend

docker compose exec app pnpm --filter teammapper-frontend run build:packages

• Start frontend and backend at once

docker compose exec app pnpm run dev

or start frontend and backend separately

# Open two terminal sessions on your host machine
# In first terminal session
    docker compose exec app pnpm --filter teammapper-backend start
# In second terminal session
    docker compose exec app pnpm --filter teammapper-frontend start

• Visit the frontend in http://localhost:4200

Test

• Create a test database

docker compose exec postgres createdb -e -U teammapper-user -W teammapper-backend-test

• Execute the tests

docker compose exec app pnpm --filter teammapper-backend run test:e2e

Production

• Duplicate and rename .env.default

cp .env.default .env.prod

• Adjust all configs in .env.prod, e.g. database settings, ports, enable ssl env vars if necessary

• Start everything at once (including a forced build):

docker compose --file docker-compose-prod.yml --env-file .env.prod up -d --build --force-recreate

• Go to http://localhost:3011 (if default port is used in .env.prod) to open up teammapper. Happy mapping!
• Optional commands:

docker compose --file docker-compose-prod.yml --env-file .env.prod build --no-cache

then:

docker compose --file docker-compose-prod.yml --env-file .env.prod up -d --force-recreate

If you want to remove old data, including cached node packages and stored databases (DANGER!):

docker compose --file docker-compose-prod.yml --env-file .env.prod down -v

If you want to run prod migrations (again):

docker compose exec app_prod pnpm --filter teammapper-backend run prod:typeorm:migrate

Postgres and SSL

If needed, you can make the connection to Postgres more secure by using a SSL connection.

• Generate self-signed ssl sertificate for the postgres server on the host machine; the generated files are mounted into the docker container

mkdir -p ./ca
    openssl req -new -text -passout pass:abcd -subj /CN=localhost -out ./ca/server.req -keyout ./ca/privkey.pem
    openssl rsa -in ./ca/privkey.pem -passin pass:abcd -out ./ca/server.key
    openssl req -x509 -in ./ca/server.req -text -key ./ca/server.key -out ./ca/server.crt
    chmod 600 ./ca/server.key
    test $(uname -s) = Linux && chown 70 ./ca/server.key

And uncomment the line:

# command: -c ssl=on -c ssl_cert_file=/var/lib/postgresql/server.crt -c ssl_key_file=/var/lib/postgresql/server.key

within the docker-compose-prod file.

Running jobs

Trigger delete job (also executed daily with cron task scheduler):

docker compose --file docker-compose-prod.yml --env-file .env.prod exec app_prod pnpm --filter teammapper-backend run prod:data:maps:cleanup

Running further queries

Example of running sql via typeorm:

docker compose --file docker-compose-prod.yml --env-file .env.prod exec app_prod pnpm --filter teammapper-backend exec typeorm query "select * from mmp_node" --dataSource ./dist/data-source.js

Default Settings

The following files contain configurations for default settings:

1. /teammapper-backend/config/settings.dev.json

1. /teammapper-backend/config/settings.prod.json

1. /config/settings.override.json

The settings are conceptually divided into:

• System Settings: Settings provided by the application, which are not cached by the frontend and can only be adjusted in the backend
• User Settings: values configured by the user in the frontend, which persist separately and override system defaults where applicable.

• pictograms: Disables/Enables the pictogram feature (default: disabled). Note: You have to set this flag before build time in the JSON config!
• ai: Disables/Enables AI functionality like generating mindmaps with AI. Can be controlled via the AI_ENABLED environment variable (default: false).

Environment variable overrides

The following environment variables override the feature flags from the JSON config:

| Variable | Description | Default | | --- | --- | --- | | AI_ENABLED | Enable AI features (mindmap generation) | false | | DELETE_AFTER_DAYS | Number of days before mindmaps are deleted | 30 | | LOG_LEVEL | NestJS log verbosity (error, warn, log, debug, verbose) | debug in DEV, log otherwise |

Further details

• Once this docker volume is initialized after the first docker compose up, the database-related variables in .env.prod will not have any effect; please have this in mind => you will then need to setup your database manually

Contributing

The frontend compiles under strict: true and Angular's strictTemplates. strictNullChecks stays off while we turn it on one area at a time. Run both checks before you open a PR:

pnpm --filter teammapper-frontend run tsc        # TypeScript
pnpm --filter teammapper-frontend run build:dev  # Angular templates

1. Fork it
2. Create your feature branch (git checkout -b fooBar)
3. Commit your changes (git commit -am 'Add some fooBar')
4. Push to the branch (git push origin fooBar)
5. Create a new Pull Request
