ts-interface-route-validator

Module to validate API responses against TypeScript interfaces

Install

npm i @dreipol/ts-interface-route-validator

Setup

First create a file to execute the validator.

const ROUTES = require('./routes.json'); // load the config file
const { validateRoutes } = require('@dreipol/ts-interface-route-validator'); // include the validator
const searchPath = `${process.cwd()}/**/*.ts`; // point to the location where your interfaces are stored

validateRoutes(searchPath, ROUTES);

If you don't want to use the default interface name generator you can pass your own function as third parameter. The default function will access the plugin.type property and transform the type string into an interface name.

dyn-title-lead will be transformed to ITitleLeadPlugin

If you wan't to use a custom generator you can to it like this

function getInterfaceName(plugin: PluginInterface): string {
    let interfaceNames = plugin.type
        .replace('dyn', '')
        .replace(/-\w/ig, (chr) => {
            return chr.toUpperCase();
        })
        .split('-');
    interfaceNames.unshift('I');
    interfaceNames.push('Plugin');
    return interfaceNames.join('');
}

validateRoutes(searchPath, ROUTES, getInterfaceName);

The code above will print the following in your CLI

✔ IVideoTeaserPlugin dyn-video-teaser
✔ ITitleLeadPlugin dyn-title-lead
✔ IServiceTeaserPlugin dyn-service-teaser
✖ http://localhost:8000/en/api/pages - NewsTeaserPlugin NewsTeaserPlugin.content.news[0] should NOT have additional properties  {"additionalProperty":"date"}
✖ http://localhost:8000/en/api/pages - NewsTeaserPlugin NewsTeaserPlugin.content.news[1] should NOT have additional properties  {"additionalProperty":"date"}
✖ http://localhost:8000/en/api/pages/about-us - No Interface for dyn-team-list

Config

There is a simple config file required. In the example above it's the routes.json file. In there we define a couple of routes/api endpoints we want to validate. In Addition we have to provide a dataPath. This path is required to access the data of the returned response.

[
    {
        "urls": [
            "http://localhost:8000/en/api/pages",
            "http://localhost:8000/en/api/pages/about-us"
        ],
        "dataPath": "data.containers.main.plugins"
    }
]
