ts-outcome/dist/index.js

A small set of Typescript utils to represent success / failure in a more sane way than throwing errors

/**
 * Creates a successful Outcome.
 */
export function makeSuccess(value) {
    return { type: 'success', isSuccess: true, value };
}
/**
 * Creates an error Outcome.
 */
export function makeError(error) {
    return { type: 'error', isSuccess: false, error };
}
/**
 * Checks if an Outcome is successful.
 */
export function isSuccess(result) {
    return result.type === 'success';
}
/**
 * Checks if an Outcome is an error.
 */
export function isError(result) {
    return result.type === 'error';
}
