When you get a new Mac, it is immediately usable because it has macOS on it. When you get a new phone, PC, or tablet, they come with or you quickly install an operating system which provides some basic functionality, and, more importantly, a framework for extending what you can do with it. When you get a Solid pod -- a chunk of data storage somewhere that you control -- then you should have an operating system which allows you to make immediate use of it, but also provides a framework for you to do more and more things with more and more people.

Some of these have been achieved but there is a huge amount of work to do.

• SolidOS should be a complete web-technology-based operating system for any new computer or data store.

• When running as a native app, on laptop or desktop or mobile, it should allow the user to use their own local file system in very much the same way as a solid pod. (This currently works with Electron and rdflib). Users should be able to work Local first.

• The User Interface should accommodate a wide range of devices, screen sizes, bandwidth. The project was originally targeted at laptop, and responsive and reactive design is important in new work.

• SolidOS, unlike a typical set of native applications, is very interconnected. You can do anything with anything - so data from different applications interlinks in a more powerful way so as to solve real life problems powerfully and naturally. You can start a chat about anything, with anyone or combination of people who have solid IDs. You can adopt anything as the target of a task you want to track later. You can like, flag, keyword, bookmark anything. So one application will use others in a recursive way to get its job done.

• You should be able to set SolidOS up for any existing folders you have full of things like photos and music, and it should let you listen to them, look at them, and share them very flexibly with anyone in the world.

• When used with a Solid pod, because that is on the web, SolidOS provides the public view -- the interactive interface -- that the user has with the rest of the world. Like when everyone had their own home page on the web, they have that power again to express themselves and their affiliation and their products, and to court interaction, such as collaborative work with others, or commerce. The way this public home page appears to others is very customizable, so the user, individual or business can be proud of it.

• SolidOS should be modular, dynamically loading new code modules in real time as a function of a user's preferences for handling different types of data with different new SolidOS applets, be it finance, fitness, or fishing.

• A module providing new functionality in a new domain should be able to appear as a module in SolidOS or as a stand-alone app, or both.

• The modularity of the system should allow you set yourself up with any set of apps, or indeed the user should be able to configure SolidOS to replace itself with the user's own choice of alternative SolidOS version. All SolidOS implementations should allow the user to change this selection.

• SolidOS should allow people to create, bit by bit, a web of social linked data of their work and their play, and their lives.

SolidOS is composed of serveral other repositories. The major ones are shown above.

The current main way of getting SolidOS is as a big JS package, mashlib.js.

The mashlib can be used as the core of a native application. It has been tried on macOS using electron.

The mashlib has been used before, originally in various apps, in specific data interactions in different domains. It has been used in a browser extension (in Firefox and later Chrome) to add data-handling capacity as native to the browser itself.

Portions of the SolidOS functionality may be made available as a stand-alone web app. This app allows you to look at what a given thing, like a folder in someone's pod, looks like in SolidOS. It doesn't have the general navigation, preferences, etc.

The data kitchen is a native Mac/Windows/Linux App which provides the SolidOS functionality to your solid pods, but also your local files on your laptop/desktop. Your Documents folder can be a Solid pod too! This is very much in early experimental stage. Jeff's version on github

Solid pod servers can serve this HTML view as a sort of ad-hoc, rather crude browser extension, which loads the library and then tries to work as though the browser had been extended to understand data. This has been done by solid servers for several years.

This refers to a specific way in which the SolidOS is deployed for users who at first only have a conventional web browser - a hypertext browser not a data browser. It is a hack -- in the original computing sense of a crafty, though not beautiful, little thing which gets the job done.

How does the data browser work?

1. The user goes with a normal web browser to access some data object (like a to-do list).
2. The server sees the browser doesn't understand the data natively.
3. The server sends back a little placeholder HTML file, databrowser.html, instead of the data.
4. The databrowser.html file loads the mashlib.js Javascript library, which can now understand the data.
5. The mashlib.js then re-requests the original data, but accepting data formats.
6. The server supplies the actual data of the to-do list or whatever it was.
7. The mashlib.js code provides an editable visualization of the data.

The mashlib human interface is read-write: where the user is allowed to edit: it lets them edit the data and create new things. It is live, in that often the data browser signed up (using a websocket) for any changes which other users make, so users' screens are synchronized.

A major limitation of the data browser hack is that current web browsers are made to distrust any code loaded from one domain that uses data from another domain. This makes it hard, strangely complicated, and sometimes impossible to do some things.

In addition to the well-established deployment patterns above, there are many other ways of developing with SolidOS and the mashlib and we look forward to learning what is possible and needed.

PRs are always welcome.

We can add you to the SolidOS team, which has a pod and some solid space to work.

The scripts in this repository are intended to ease the development of Solid OS.

These scripts allow you to install automatically several of the component repositories of the Solid OS system, and coordinate their development.

These scripts use a subset of the functionality in Lerna to bootstrap the various projects. Do note that you cannot use it to manage multi-package repositories like you normally would want to with Lerna.

The NPM scripts are using bash scripts. These might not work if you're developing on a Windows machine. Let us know if you want support for this.

Many of the repositories used in this project rely upon Node Version Manager to maintain the Node version used to build the project. Be sure to have it installed.

These scripts assume that ~/.nvm/nvm.sh is a script that is sourced and establishes the nvm shell functions. Depending on your nvm installation and OS, it may be necessary to manually create a symlink from ~/.nvm/nvm.sh to your installed version of nvm.sh. For example, on macOS using Homebrew, the following command will be sufficient to allow these SolidOS scripts to use nvm:

cd ~/.nvm
ln -s /usr/local/opt/nvm/nvm.sh nvm.sh

git clone https://github.com/solid/solidos
cd solidos
nvm install 12.7.0 # to satisfy https://github.com/solid/mashlib/blob/main/.nvmrc
nvm install 12.19.1 # to satisfy https://github.com/linkeddata/rdflib.js/blob/main/.nvmrc
nvm install 13.14.0 # to satisfy https://github.com/solid/node-solid-server/blob/main/.nvmrc
# ... and maybe other versions if build errors tell you so ...
npm run setup

Run this the first time you setup your folder. By default this sets up some repos for you:

• mashlib: the glue that puts everything together
• node-solid-server: the server that allows you to test your changes
• solid-panes: the part that handles everything reg panes
• solid-ui: a lot of reusable code for solid-panes and the various pane-repos

Any changes you do in this projects need to be committed to their original repos and eventually be pushed to NPM manually (this is the part of Lerna that we do not use for this project).

You can start your server and test out your code with:

npm start

An important part of this script is that it bootstraps the various packages using Lerna. If you for some reason (e.g. you've run npm install in any of the projects) need to bootstrap the packages again and don't want to stop the server, you can do npx lerna bootstrap --force-local (the --force-local makes sure that packages are bootstrapped even if versions don't match).

Some projects require you to build a package before you can see changes, so check the various package.json files to see which scripts are available. You can usually do npm run build, and some also supports npm run watch which builds a new version each time you do a local change.

There are a couple of ways you can test and debug your changes to the various projects. Before we go into the details, here's a simplified view of the dependencies:

node-solid-server --> rdflib
node-solid-server --> mashlib --> rdflib
node-solid-server --> mashlib --> solid-panes --> rdflib
node-solid-server --> mashlib --> solid-panes --> solid-ui --> rdflib
node-solid-server --> mashlib --> solid-panes --> [pane project] --> solid-ui --> rdflib

This means that if you do a change in solid-panes and want to see the result on your local NSS, you need to make sure that mashlib compiles the changes as well. Similarly, if you do changes to solid-ui, and some pane relies on those changes, you need to make sure that the pane compiles those changes, that solid-panes compiles the changes from the pane, and finally that mashlib compiles the changes from solid-panes. This quickly becomes hard to track, so we've devised a couple of ways to mitigate this.

This repository is a powerful setup for developing the full stack, from rdflib, to solid-ui, to solid-panes, to mashlib, to node-solid-server. If you are just developing a pane then you will probably find the Solid Pane Tester more useful. There, you will be able to see the effect of your changes in 5 seconds, whereas a full recompile takes more like 5 minutes. You can also just run the pane tester within this repository, at workspaces/solid-panes/dev/.

To debug a component from solid-ui in isolation, when you do not need the surrounding solid-pane, you can run storybook in the solid-ui repository.

To debug solid-ui within a pane, you can combine the solid-ui to solid-panes link with the Pane Tester. For instance, when debugging code from solid-ui that affects the Sharing pane, you might run npm start to set the links between the workspaces, then run npm run watch in the solid-ui workspace and use the Solid Pane Tester in the solid-panes workspace, with the Sharing pane in workspaces/solid-panes/dev/pane/, to see how your edits in solid-ui affect the Sharing pane.

Run:

npm run add rdflib
cd workspaces/rdflib
npm install
npm run build:esm
cd ../..
npm start
[Ctrl+C]
cd workspaces/solid-ui
npm run build-lib

In another terminal window, run cd workspaces/solid-panes/dev/ ; npx webpack-dev-server.

Edit workspaces/solid-panes/dev/pane/ to have the pane you want to debug.

Open http://localhost:9000 and run renderPane('http://example.com/#me') in the console to check if your setup works.

Then, under workspaces/rdflib, make your change, for instance add a console.log somewhere. It should then be enough to run npm run watch in workspaces/rdflib to make your changes in rdflib appear in the browser.

You can also combine this with cd workspaces/solid-ui ; npm run watch so that you can combine edits in rdflib with edits in solid-ui, but if you're only editing rdflib, the npm run watch in workspaces/rdflib should be enough.

You can also test changes directly on the instance of NSS that starts when running npm start in this repository. There is a watch-script that you can start doing npm run watch that triggers the watch-script for mashlib, solid-ui, and solid-panes. If you want to run watch-script for rdflib or any of the panes, you'll have to open another terminal window, navigate to the respective project and start its watch-script doing npm run watch.

The output for the watch-script can be a bit difficult to interpret, since all output for mashlib, solid-ui, and solid-panes are presented in the same window, so you might also consider having each watch scripts running in a separate terminal window. The downside using this approach is that at its worst you'll have five separate watch-scripts running (in addition to the terminal window where you started the server) when working on a pane that needs to pick up a change in rdflib. If you find this unwieldy for your setup, or requiring too much resources, you should consider the Solid Pane Tester strategy instead.

You can add other projects to your workspaces to do local changes. We've mapped most projects that are related to mashlib for you, so you can simply do:

npm run add <name-of-repo>

For the projects that we haven't mapped you need to manually give the URL to the Git repo.

npm run add <name-of-repo> <git-url-of-repo>

This removes the dependency itself and cleans up dependencies.

npm run delete <name-of-repo>

If you for some reason aren't able to get your setup working, you should double-check that Lerna actually manages to bootstrap the repositories. One way of doing this is to check node_modules in one of them and verify that the dependency that should be bootstrapped is actually a symlink to the corresponding repository (e.g. check that workspaces/mashlib/node_modules/solid-ui links to workspaces/solid-ui ). If it doesn't, it is usually because of different version (e.g. mashlib expects a newer version of solid-ui than the one you have locally). Make sure that these are aligned, then bootstrap again by running npm start or do it manually with npx lerna bootstrap (must be run in the root of this repo).

When you made a change in one of the repositories and you want that change to be included in a new version of Solid OS / NSS, do the following:

• make sure you have access to all the github repo's and all the npm package (ask Tim or Michiel if needed)
• get a VPS running Ubuntu, for instance at https://digitalocean.com, and ssh into it as root

tmux new
adduser --shell /bin/bash --home /home/build --ingroup sudo build
su - build
whoami
sudo whoami

Then:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.0/install.sh | bash
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
nvm install 15
nvm use 15

ssh-keygen -t ed25519 -C "[email protected]"
git config --global user.name "Solid OS Build (Michiel)"
git config --global user.email "[email protected]"
cat .ssh/id_ed25519.pub
npm login

Log in to npm with your npm account and add the SSH public key to your GitHub account. Then continue:

git clone https://github.com/solid/solidos
cd solidos
npm run install-nvm
npm run release
