Testing

ssg-api is a provided as a native ESM package, so:

• you may want to enable them in your node version, using the --experimental-vm-modules option;
• it may not be supported by all test frameworks out of the box.

For instance, Jest will require some specifics in its jest.config.js to transform the package code (here as ts-jest config):

/** @type {import("ts-jest/dist/types").InitialOptionsTsJest} */
export default {
  preset: "ts-jest/presets/default-esm",
  modulePaths: ["node_modules", "src", "."],
  testEnvironment: "node",
  modulePathIgnorePatterns: ["dist\/.*", "node_modules/(?!@googlemaps)/"]
}

or if you want to avoid test framework headaches, just use testscript ;)
