runMigration doesn't support typescript files as input

Expected Behavior

Something like the following should execute.

      const config: RunMigrationConfig = {
        filePath: 'someFilePath.ts',
        spaceId,
        environmentId,
        accessToken,
      };

      await runMigration(config);

Actual Behavior

The contentful-schema/1/00-languages.ts script could not be parsed, as it seems to contain syntax errors.

contentful-schema/1/00-languages.ts:1
import { MigrationFunction } from 'contentful-migration';
^^^^^^

Context

Trying to run multiple migration files in sequence based on various rules. It makes sense to use runMigration rather running command line calls from within a ts script.

Environment

Node Version: 12.19.0 “contentful-migration”: “^4.0.6”,

@phawxby I’m just running everything through ts-node, no compilation required and it loads typescript files without issue.

e.g. ts-node migration.ts where migration.ts is:

import { runMigration } from 'contentful-migration';

//...

await runMigration({
  filePath: '/users/johnny/someFilePath.ts',
  spaceId,
  environmentId,
  accessToken,
});

edit: updated the example to contain an absolute file path, as is required by runMigration, so people know about it.

[OriginalEXE]

For anyone getting a TypeError: migrationCreator is not a function error, make sure you use module.exports instead of export default. This is what your migration file would look like:

import { MigrationFunction } from "contentful-migration";

const migrate: MigrationFunction = (migration) => {
  
};

module.exports = migrate;
