TypeScript

TypeScript is a strongly typed programming language and the AnyWayData TypeScript option is useful when you need typed, copy/paste-ready data for tests, fixtures, demos, and prototypes.

What is TypeScript Data Output?

TypeScript can represent table-like data using arrays of anonymous objects or arrays of class instances.

For example, a typed array of anonymous objects:

const data: Array<Record<string, unknown>> = [
    {"user": "Jesse.Bradtke97", "name": "Corine"},
    {"user": "Cielo.Little", "name": "Zander"}
];

In the example above:

• each row is represented as an object literal using key/value pairs
• object keys come from the column headers
• row objects are collected in a typed TypeScript array

AnyWayData can also generate class-instance output where each row is represented as an instance of a named TypeScript class.

How is TypeScript Output different from JSON and Javascript?

JSON is a language-independent data format and JavaScript object arrays are JavaScript syntax.

TypeScript output uses TypeScript syntax and typing concepts:

• rows can be emitted as anonymous object literals or named class instances
• output can be generated as Array<T> or T[]
• values can be emitted as quoted strings or numeric literals
• output can be assigned to a named, typed variable

Unlike JSON, TypeScript output is designed to be used directly in TypeScript code.

AnyWayData Support for TypeScript

AnyWayData currently supports exporting data to TypeScript format.

You can configure output options such as:

• collection type (Array<T> or T[])
• variable assignment and naming
• number conversion (quoted vs unquoted)
• anonymous-object vs class-instance output
• pretty print indentation and custom delimiter

TypeScript output can be generated from the same grid data used for the other supported export formats.

Unit Test Code Generation

You can also generate data-driven test scaffolding for TypeScript using frameworks: jest, vitest, mocha.
