# esbuild-plugin-jsonschema

Compile and pack JSON schema definitions on import using esbuild

## Installation

The package is released to npm as `@offen/esbuild-plugin-jsonschema`:

```

npm install @offen/esbuild-plugin-jsonschema -D

```

## Usage

In the default configuration, the transform is applied to all files with a `.schema` or `.schema.json` extension. The transformed module will export the packed AJV `validate` function.

In your application:

```js

const validateFoo = require('./foo.schema')

const ok = validateFoo({ foo: true })

if (!ok) {

  console.log(validateFoo.errors)

  throw new Error('Foo did not validate')

}

```

When bundling:

```js

const esbuild = require('esbuild')

const jsonschemaPlugin = require('@offen/esbuild-plugin-jsonschema')

esbuild.build({

  entryPoints: ['app.js'],

  bundle: true,

  plugins: [jsonschemaPlugin()],

  outdir: './public'

})

```

### Defining schemas

Schemas are expected to be defined in JSON format and saved as `.schema` files:

```json

{

  "type": "string",

  "maxLength": 128

}

```

## Options

The transform accepts the following options as its 2nd arguments:

### `secure`

By default, this plugin only compiles ["secure" schemas][secure]. This can be disabled by passing `secure: false` to the transform.

[secure]: https://github.com/ajv-validator/ajv/tree/521c3a53f15f5502fb4a734194932535d311267c#security-considerations

### `filter`

By default, files with a `.schema` or a `.schema.json` extension are compiled. If you have different requirements you can pass a Regexp to `filter` for the plugin to use.

### `addFormats`

Includes [ajv-formats](https://github.com/ajv-validator/ajv-formats). Default `true`.

### `ajvOptions`

Custom [options](https://ajv.js.org/options.html) to be passed to Ajv constructor.

## Releasing a new version

New versions can be released using `npm version `. Make sure you are authenticated against the `@offen` scope with npm.
