Simple example of schema: ```json { "type": "object", "properties": { "name": { "description": "This is description of option.", "type": "string" } }, "additionalProperties": false } ``` ### `options` Type: `Object` Object with options. ```js import schema from "./path/to/schema.json"; import { validate } from "schema-utils"; const options = { foo: "bar" }; validate(schema, { name: 123 }, { name: "MyPlugin" }); ``` ### `configuration` Allow to configure validator. There is an alternative method to configure the `name` and`baseDataPath` options via the `title` property in the schema. For example: ```json { "title": "My Loader options", "type": "object", "properties": { "name": { "description": "This is description of option.", "type": "string" } }, "additionalProperties": false } ``` The last word used for the `baseDataPath` option, other words used for the `name` option. Based on the example above the `name` option equals `My Loader`, the `baseDataPath` option equals `options`. #### `name` Type: `Object` Default: `"Object"` Allow to setup name in validation errors. ```js import schema from "./path/to/schema.json"; import { validate } from "schema-utils"; const options = { foo: "bar" }; validate(schema, options, { name: "MyPlugin" }); ``` ```shell Invalid configuration object. MyPlugin has been initialised using a configuration object that does not match the API schema. - configuration.optionName should be a integer. ``` #### `baseDataPath` Type: `String` Default: `"configuration"` Allow to setup base data path in validation errors. ```js import schema from "./path/to/schema.json"; import { validate } from "schema-utils"; const options = { foo: "bar" }; validate(schema, options, { name: "MyPlugin", baseDataPath: "options" }); ``` ```shell Invalid options object. MyPlugin has been initialised using an options object that does not match the API schema. - options.optionName should be a integer. ``` #### `postFormatter` Type: `Function` Default: `undefined` Allow to reformat errors. ```js import schema from "./path/to/schema.json"; import { validate } from "schema-utils"; const options = { foo: "bar" }; validate(schema, options, { name: "MyPlugin", postFormatter: (formattedError, error) => { if (error.keyword === "type") { return `${formattedError}\nAdditional Information.`; } return formattedError; }, }); ``` ```shell Invalid options object. MyPlugin has been initialized using an options object that does not match the API schema. - options.optionName should be a integer. Additional Information. ``` ## Examples **schema.json** ```json { "type": "object", "properties": { "name": { "type": "string" }, "test": { "anyOf": [ { "type": "array" }, { "type": "string" }, { "instanceof": "RegExp" } ] }, "transform": { "instanceof": "Function" }, "sourceMap": { "type": "boolean" } }, "additionalProperties": false } ``` ### `Loader` ```js import { getOptions } from "loader-utils"; import { validate } from "schema-utils"; import schema from "path/to/schema.json"; function loader(src, map) { const options = getOptions(this); validate(schema, options, { name: "Loader Name", baseDataPath: "options", }); // Code... } export default loader; ``` ### `Plugin` ```js import { validate } from "schema-utils"; import schema from "path/to/schema.json"; class Plugin { constructor(options) { validate(schema, options, { name: "Plugin Name", baseDataPath: "options", }); this.options = options; } apply(compiler) { // Code... } } export default Plugin; ``` ## Contributing Please take a moment to read our contributing guidelines if you haven't yet done so.
