Data Factory

Reaction Data Factory creates a simple fixture factory from SimpleSchema definitions for testing and seeding applications.

Install

``sh
npm install @reactioncommerce/data-factory
`




Usage

Adding schemas to the Factory object.
` js
import SimpleSchema from 'simpl-schema';
import { createFactoryForSchema } from "@reactioncommerce/data-factory";

const Example = new SimpleSchema({
strProp: String,
boolProp: Boolean,
});
createFactoryForSchema("Example", Example);
`

Creating mock data structures.
` js
import { Factory } from "@reactioncommerce/data-factory";
const mockExample = Factory.Example.makeOne();
// mockExample output
// { _id: "e02993ea96d7", strProp: "mockStrProp", boolProp: true }

const mockExamples = Factory.Example.makeMany(2);
// mockExamples output
// [{ _id: "e02993ea96d7", strProp: "mockStrProp", boolProp: true }, { _id: "3ff4e0634ecc", strProp: "mockStrProp", boolProp: false }]
`

Creating mock data with custom property values.
` js
const mockExample = Factory.Example.makeOne({ strProp: "Custom Value" });
// mockExample output
// { _id: "e02993ea96d7", strProp: "Custom Value", boolProp: true }
`

Creating mock data with custom property function.
` js
const mockExamples = Factory.Example.makeMany(3, { _id: (i) => (i + 100).toString() });
// mockExamples output
// [{ _id: "100", strProp: "mockStrProp", boolProp: true }, { _id: "101", strProp: "mockStrProp", boolProp: false }], { _id: "102", strProp: "mockStrProp", boolProp: false }]
`

Mock Values

When you call makeOne or makeMany, a full document (including all nested schemas recursively) is automatically built based on the schema. The value of each node is determined like this:

- If mockValue is found in the schema definition, use that value. mockValue is not part of normal SimpleSchema but is added by and checked by this package.
- If defaultValue is found in the schema definition, use that value.
- If autoValue is found in the schema definition, use it to get a value.
- If allowedValues is found in the schema definition, use a random item from the array as the value.
- If all else fails, use faker.js to generate a random value of the type specified in the schema definition. For Number fields, the min and max values are respected when generating a random number. For String fields, the regEx value will be used if it matches one of the SimpleSchema.RegEx.*

Thanks

Thanks to @MaxGuitet and the team at Cambridge Software for their work on simpl-schema-mockdoc that heavily influenced this package.
