jsonschema.dev

What is this?

This is the repository for the code that runs the jsonschema.dev website.

jsonschema.dev is a web based JSON Schema playground.

JSON Schema is a vocabulary allow for the validation and annotation of JSON documents... and a few other things.

Why?

Running the JSON Schema slack server has demonstrated there is no solution to easily test and share JSON Schema documents. There are other web based tools which offer a JSON Schema playground, however they run validation on the server, while jsonschema.dev runs all validation in browser using ajv.

This tool enables the JSON Schema community to find help easier in the same way jsfiddle enabled the javascript community to share and demo problems and solutions.

JSON Schema?

The chances are that if you're here, you probably don't need selling on the idea that JSON Schema is pretty useful... but just in case:

JSON Schema is a personal IETF draft specification proposal. According to the IETF definition of personal drafts, it's not advised to actually use the specification, and is intended to test concepts and gather feedback, however JSON Schema has been used in production by many top companies for years.

The OpenAPI specification (formally Swagger) uses a subset of JSON Schema specification to define payloads.

The main javascript package for JSON Schema boasts many dependants, including Webpack and eslint.

The most popular text editor / IDE, Microsoft's VS Code, supports JSON Schema validation out of the box.

Here are some of the other companies and organisations that use JSON Schema, from a presentation. (These are not endorsements.)

This project uses vue.

It is expected that you have some familairty with CLI and node.

It's recommended that you use nvm to install and manage node.

You will need to install node (probably using nvm) and then yarn (an alternative to npm).

Once installed, check out this git repository and run yarn with the repository root as your current working directory.

For local development, run yarn run serve.

For production build test, run yarn run build.

For more details, see the Vue CLI docs.

jsonschema.dev is automagically deployed to netlify using the master branch.

Netlify also provides Pull Request previews, which will automagically appear when a PR is created or new commits are pushed to the associated branch.

I have questions...
