OSL is a simple shared list application. Typical uses include shopping lists of course, and any other small todo-list that needs to be used collaboratively.

The current implementation provides the following features:

• Multiple boards (can be disabled, see VUE_APP_SINGLEBOARD_MODE)
• Each board with multiple lists
• Real-time sync between users
• Items with the following fields: name, quantity, details
• Checkable items
• 2 display modes for items (unchecked only / checked only, sorted by check time)
• Intuitive search
• Mobile-first UI with swipeable items
• PWA basic support
• Partial internationalisation (i18n)
  • Only EN and FR languages are available at that time, but PR are welcome for more! See examples here.

But, at this date it lacks the following:

• Full PWA support with offline mode and deferred sync

Before v2, all of the lists on an instance were available to all users.

Version 2 introduces a new feature called "boards". It's simply a way to group lists together under a common name. That name can then be shared so that people use the lists from a board collaboratively.

But, you might want to disable that feature and keep using a unique board for your whole instance. In that case, just use the provided VUE_APP_SINGLEBOARD_MODE environment variable.

But have no fear, you can always:

• Switch from singleboard mode to multi-board
  • In that case you'll have to create a new board and choose it as target for existing lists with the provided CLI tool.
• Switch from multi-board mode to singleboard
  • In that case you can choose which lists to migrate to the special unique board, but you'll lose access to all other lists (they are not deleted, just not accessible anymore)

See next § for instructions on how to enable one mode or the other.

Version 2 has added the multiboard feature which changes the default mode the application runs into.

If you already had a working v1, and would like to upgrade to v2 please follow the steps below:

⚠ Back up your data before proceeding!

• Make sure you set the VUE_APP_SINGLEBOARD_MODE to 1
• Once started, use the CLI to migrate existing lists to the special board used as common parent for lists in "singleboard" mode.

  docker-compose exec app node cli.js board:create --singleboard
  docker-compose exec app node cli.js list:move-to-board --all --singleboard

• Use the application as usual (you might have to clear your browser's cache to make sure there's no invalid data left).

• Make sure VUE_APP_SINGLEBOARD_MODE is not set or set to 0
• Create a new board with the name of your choice

  # Get the created board's slug from the output and use it in the following command
  docker-compose exec app node cli.js board:create my-board
  docker-compose exec app node cli.js list:move-to-board --all --board my-board

• Open the application, and from the home screen open the board you've just created to find your lists.

With a running MongoDB container as mymongo on the host:

docker-compose up -d

By default, the embedded robots.txt prevents search engines from browsing the application:

User-agent: *
Disallow: /

You can change this behavior by mounting the robots.txt of your choice at /app/robots.txt in the container.

OSL uses a WebSocket to allow server-to-client communication. So using a reverse-proxy to forward the connection implies the presence of the following sections below in the corresponding virtual host.

Replace 127.0.0.1 and 8080 with the IP of the OSL host if your RP is not the host itself and/or if you're using another port.

<Proxy *>
    Allow from all
</Proxy>
ProxyPass         /  http://127.0.0.1:8080/
ProxyPassReverse  /  http://127.0.0.1:8080/
ProxyPreserveHost On

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*)           ws://127.0.0.1:8080/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*)           http://127.0.0.1:8080/$1 [P,L]

location / {
    proxy_set_header    Host $host;
    proxy_set_header    X-Real-IP $remote_addr;
    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header    X-Forwarded-Proto $scheme;
    proxy_pass          http://localhost:8080;

    proxy_http_version  1.1;
    proxy_set_header    Upgrade $http_upgrade;
    proxy_set_header    Connection "Upgrade";
    
    proxy_redirect      http://localhost:8080 https://ourshoppinglist.myhost;
}

Remember to set the BASE_URL variable to the matching web root on each instance.

Make sure you set VUE_APP_LOCALSTORAGE_KEY_PREFIX to a unique value too, otherwise clients switching from one instance to another might corrupt the internal cache in their browser.

Example:

• 1st instance on https://my.host/public-osl
  • BASE_URL = public-osl/
  • VUE_APP_LOCALSTORAGE_KEY_PREFIX = OSL1_
• 2nd instance on https://my.host/private-osl
  • BASE_URL = private-osl/
  • VUE_APP_LOCALSTORAGE_KEY_PREFIX = OSL2_
• etc.

You can use the standard DEBUG environment variable to enable the verbose mode of the server:

Example to log all operations related to socket-io (WebSocket) and the URL rewrite process (when using a custom BASE_URL):

DEBUG=socket.io:server,express-urlrewrite

Or if you need to log everything:

DEBUG=*

From the original release until june 2024, the stack was shipped with mongo:4 but this version of MongoDB is deprecated and you can safely upgrade to MongoDB 7 while keeping your existing data.

Use the provided automated script as follows:

# Make a backup with mongodump first!
docker-compose exec -T mongodb mongodump -d osl --archive > osl-backup.archive

bash doc/update-mongo7.sh

🐋 This method also uses Docker, but with the local source files mounted into the node container.

First of all, clone this project in the directory of your choice. Then from it:

make dev-pull
make dev-init
make dev-upd

Now start the Webpack Development Server with

make dev-watch

If you don't, you'll get 504 errors in the console on /sockjs-node/* requests and you won't get hot reloading on changes.

If you want to enter the container, just use

make dev-shell

Translations can be very easily added and improved using the files from the client/src/locales/ directory.

If you want to translate OSL in a new language, feel free to add your contribution using Weblate.
Register on Weblate and go to https://hosted.weblate.org/projects/our-shopping-list/client-src-locales/

In development mode, the service worker is not enabled. To workaround this limitation, you may want to ponctually build the JS bundle in "production" mode.

Here's how:

make dev-shell

cd client/
NODE_ENV=production yarn build

Then reload the page in your browser and the SW should be activated. You have to make sure you are running the app with TLS enabled. Use the ENABLE_TLS variable to use the embedded TLS proxy if needed.

Use the provided automated script as follows:

export COMPOSE_FILE=docker-compose.dev.yml
export DOCKER_COMPOSE_FILE=docker-compose.dev.yml
bash doc/update-mongo7.sh
