# Community Solid Server: running your own Solid Pod with JSON configuration

> Community Solid Server is a TypeScript implementation of the Solid specifications that gives you a personal data Pod and an identity provider, configured entirely through JSON files and wired together at runtime with Components.js. It is the most complete Solid server you can run yourself, and its complexity is the price of that completeness.

## A personal Pod with a WebID, not a shared drive

Community Solid Server gives you a Solid Pod and an identity. The README describes it as open software that provides a Solid Pod and identity, where the Pod acts as your own personal storage space so you can share data with people and Solid applications.

That framing matters, because a Pod is not a folder with a login page. In the Solid model, the identifier and the data are coupled: your WebID is a document that describes who you are and where your resources live, and it is served from the same server as the data. Applications read your WebID to discover how to authenticate against you and how to read what you publish. The project topics make the format level explicit, with ldp for Linked Data Platform, linked-data and rdf for the data model.

The audience is stated in the README as three groups: people who want to try having their own Pod, developers who want to quickly create and test Solid apps, and researchers designing new features for Solid. The first group gets a working server in one command. The second gets a modular base to build against. The third gets a reference implementation to experiment on.

What the project is not is a general purpose web server with a Solid skin. The README calls it an open and modular implementation of the Solid specifications, and the modularity is a design goal rather than an accident: the server allows writing and plugging in custom modules without altering its base source code.

## Components.js wiring, where the real complexity lives

Configuration is the part that decides whether this project feels manageable or unmanageable, so it is worth being concrete.

Substantial changes to server behaviour are made through JSON configuration files. The Community Solid Server uses Components.js to specify how modules and components need to be wired together at runtime. In other words, a configuration file is not a list of settings; it is a graph of instantiated components, and the same server binary can be assembled into different shapes depending on which configuration you hand it.

The package manifest shows how this is reflected in the artifact. Besides the usual main and types entries, the package publishes an `lsd:module` pointer to a Linked Software Dependencies bundle, an `lsd:components` entry pointing at `dist/components/components.jsonld`, and a set of `lsd:importPaths` mapping versioned URLs such as the components and config directories to the files inside the package. The build script confirms it: the build runs the TypeScript compiler and then a components generator that reads the source directory and writes the components description.

The practical payoff is that storage, authentication and routing are all swappable components, so a deployment can change where data lives without touching the source. The cost is a learning curve that is steeper than a typical JSON settings file, and a configuration that is far easier to break in subtle ways.

## Starting a server and persisting the Pod

Running it takes Node.js 18.0 or higher, and the README gives a single command:

```shell
npx @solid/community-server
```

After that you visit the new server at http://localhost:3000/. Note that this default run has no persistence, so restarting loses the Pod contents.

To keep the data between restarts, pass a configuration file and a data directory:

```shell
npx @solid/community-server -c @css:config/file.json -f data/
```

The `@css:config/file.json` argument refers to the configuration shipped in the package's config directory, and `-f data/` sets the storage location for the Pod contents.

Docker is the other documented path, and the Dockerfile in the repository shows exactly how the maintainers think it should be run. It is a two stage build on node:18-alpine: the build stage copies the context, runs `npm ci --unsafe-perm && npm run build`, and the runtime stage copies only the package.json, the bin, config, dist, node_modules and templates directories into a fresh image. The runtime image creates a `/config` and a `/data` directory, exposes port 3000, sets the entrypoint to `node bin/server.js`, and defines two environment variables that define the default behaviour:

```dockerfile
ENV CSS_CONFIG=config/file.json
ENV CSS_ROOT_FILE_PATH=/data
```

So a container deployment runs in file mode by default, with the Pod data living in the mounted `/data` volume. The README also points to the documentation for Docker and other startup methods.

## Configuration lives in three separate places

Finding your way around the configuration options takes a bit of hunting, because the sources are spread across repositories and generated tools.

The `config` folder in the repository holds the shipped configurations and is linked from the README as examples and guidance on custom configurations. The configuration tutorial lives in a separate tutorials repository, and the README points to a configuration generator hosted as a website, which lets you assemble a configuration rather than write one by hand. Recipes for configuring the server are kept in yet another repository, CommunitySolidServer/recipes.

That spread is the direct consequence of the Components.js model. A configuration is code in the sense that it instantiates and connects components, so it benefits from the same tooling a codebase would: recipes that solve common problems, tutorials that walk through custom configurations, and a generator for the common cases.

It also means that a configuration is not portable in the way a settings file usually is. Because components are resolved by path and by versioned URL, a configuration written against one release can pick up different behaviour after an upgrade, and the `lsd:importPaths` entries in the manifest are keyed to a major version, which tells you the maintainers expect the mapping to change between majors.

The documentation side is reasonably organised, with separate API documentation, user documentation, and a repository of comprehensive tutorials, so the answer to most questions exists, just not always inside the main repository.

## Version cadence, alpha releases and the upgrade question

The release pattern is worth understanding before you commit to it.

The package version in the manifest is 7.2.0, and the tag list shows v7.2.0 published on 2026-07-22, alongside v8.0.0-alpha.3 from 2026-03-13 and v8.0.0-alpha.2 from 2026-03-03. So the next major version exists in alpha form and has been for months, while the stable line moved to 7.2.0 in July 2026.

The repository is not archived and the last push was on 2026-10-22, so work continues on the tree. The presence of a CHANGELOG.md, RELEASE_NOTES.md, a `.versionrc.json` file for version bumping and a commitlint configuration points to a release process with automated versioning and commit message checks, which is a good sign for upgrade notes existing.

Upgrading is therefore not free but is documented. The components manifest is versioned, so a major upgrade means new URLs for the components and config directories, and a configuration that referenced the old paths has to be revisited. The alternative is to pin a release and accept that you will be behind on the 8.x line.

The licensing is straightforward. The code is copyrighted by Inrupt Inc. and imec and available under the MIT License, with the licence text in LICENSE.md and the package manifest declaring the same. MIT permits commercial use and modification with the notice retained, so a company can run and change this server without a separate agreement. The copyright holders are worth noting because they are the organisations behind it, not an anonymous contributor pool.

## Where a Solid server is the wrong answer

The first wrong-tool case is the simplest one. If you need to publish a set of files that anyone can read, a static file host does it with less code, fewer moving parts and no identity layer. A Solid Pod is for data that individual people own and control, and for applications that need to write back under that identity. Static hosting cannot do that, but it also cannot be beaten on cost and complexity for the read only case.

The second is scale of adoption. A Solid Pod only becomes useful when other people and applications speak Solid, and the interoperability surface is still narrow in practice. The README lists researchers who want to design new features for Solid, which describes the current state of the ecosystem accurately: the interesting work is in extending the specification, not in running a fleet of production Pods.

The third is operational weight. This is a long running Node service with a persistent data directory, an identity provider, and a configuration system that has to be understood before it can be changed. The Dockerfile makes deployment straightforward, but every deployment now needs backups of the `/data` volume and attention to who holds the account credentials, because the WebID is the key to everything in the Pod.

There is also a documentation gap worth naming. The README explains how to mount a data directory, but it does not document backup, restore, migration of Pod contents between server versions, or what happens to a Pod when the identity provider configuration changes. For an experimental dataset that is acceptable. For anything you would be upset to lose, it is a gap you have to close yourself.

## Conclusion

Adopt Community Solid Server when you need a real Solid Pod with WebID identity, LDP resources and RDF data for a research project, a prototype, or a self hosted dataset, and you are prepared to run a Node service with a persistent data directory. Do not adopt it for a read only public dataset, for a static site with a handful of files, or when you need something a hosted service will run for you, because the server brings a database, a container, a configuration system and a version cadence that a static host does not need. Before deploying, read the configuration recipes and the config folder rather than starting from the default file, pin a release tag such as v7.2.0 instead of tracking main, and decide how the Pod data directory is backed up, since the README only tells you how to mount a directory, not how to restore it.

## FAQ

### How do I run a Community Solid Server locally?

Install Node.js 18.0 or higher and run `npx @solid/community-server`, then open http://localhost:3000/. To keep the Pod contents between restarts, run `npx @solid/community-server -c @css:config/file.json -f data/`.

### How is the Community Solid Server configured?

Substantial behaviour changes are made through JSON configuration files that use Components.js to specify how modules and components are wired together at runtime. Example configurations live in the config folder, with recipes, a tutorial and a configuration generator available separately.

### Can I run the Community Solid Server in Docker?

Yes. The repository Dockerfile builds on node:18-alpine, exposes port 3000, runs `node bin/server.js` as the entrypoint, and sets CSS_CONFIG to config/file.json and CSS_ROOT_FILE_PATH to /data so Pod contents live in a mounted volume.

### What licence is the Community Solid Server released under?

The code is copyrighted by Inrupt Inc. and imec and is available under the MIT License, with the licence text in LICENSE.md and the same licence declared in the package manifest.

### Which version of the Community Solid Server should I use?

The package version is 7.2.0, with the tag v7.2.0 published on 2026-07-22 and v8.0.0-alpha releases available in March 2026. Because the components manifest is versioned, pin a release tag and review the configuration when moving between major versions.
