/**
 * **This transformer is aimed to be used with ts-jest**
 *
 * Typescript AST transformer that allow to replace any "import.meta" expressions in typescript files.
 * import.meta expression is not compatible with jest in commonjs, so it needs to be stripped down
 * and replaced by a mocked object before transpilation.
 *
 * ex (jest.config):
 * ````
 * // ts-jest >= 29.0.0
 * transform: {
 *    '^.+\\.tsx?$': [
 *      'ts-jest',
 *      {
 *        diagnostics: {
 *          ignoreCodes: [1343]
 *        },
 *        astTransformers: {
 *          before: [
 *            {
 *             path: 'node_modules/ts-jest-mock-import-meta',  // or, alternatively, 'ts-jest-mock-import-meta' directly, without node_modules.
 *              options: { metaObjectReplacement: { url: 'https://www.url.com' } }
 *            }
 *          ]
 *        }
 *      }
 *    ]
 * }
 * // ts-jest < 29.0.0
 * globals: {
 *   'ts-jest': {
 *      diagnostics: {
 *        ignoreCodes: [1343]
 *      },
 *      astTransformers: {
 *        before: [
 *          {
 *              path: 'node_modules/ts-jest-mock-import-meta',  // or, alternatively, 'ts-jest-mock-import-meta' directly, without
 *              options: { metaObjectReplacement: { url: 'anyValidUrl' } }
 *          }
 *        ]
 *      }
 *    }
 * }
 * ````
 * IMPORTANT: error code 1343 MUST be ignored.
