What LXCat schema can do for you

@lxcat/schema

Package with JSON schemas, validator and Typescript types of LXCat documents.

LXCat is an open-access website for collecting, displaying, and downloading electron and ion scattering cross sections for modeling low temperature plasmas.

The validation is multi-step, first the input is checked against a JSON schema and then the quantum numbers of the members of the input reactions are checked.

Installation

pnpm install @lxcat/schema

Usage

To get Typescript type for a LXCat Cross Section Set

import type { CrossSectionSetRaw } from "@lxcat/schema/dist/css/inpu";

To get JSON schema for a LXCat Cross Section Set

import schema from "@lxcat/schema/dist/css/CrossSectionSetRaw.schema.json";

(your tsconfig should be confgured for JSON imports)

To validate a LXCat Cross Section Set document

import { Validator } from '@lxcat/schema/dist/css/validate'

const validator = new Validator()

// Some JSON document to validate
const doc = ...

if (validator.validate(doc)) {
    // is valid
    // doc is now of type CrossSectionSetRaw which can be imported with
} else {
    console.log(validator.errors)
    // List of validation errors in format of https://ajv.js.org/api.html#validation-errors
}

Install dependencies

pnpm -C packages/schema install

Generate JSON schemas

The JSON schemas (src/**/*.schema.json files) can be generated with

pnpm json

Whenever the types from which the schemas are derived are changed then this command should be run.

Tests

See code contributor doc.

API documentation

API documentation can be generated using typedoc with

npx typedoc --entryPointStrategy expand src

A docs/index.html should have been written.
