Please provide more context on what you're trying to do. It will help to see if there is a way to avoid translating manually.
It looks like you're trying to use it server-side. In that case, there are some complicating factors around providing the current user's language.
Anyways, to import translator you want to do require.main.require('./src/translator')
To translate a bunch of words there are a couple options:
Join tokens into a single string and translate it, then split the tokens, like so const tokens = [ '[[myplugin:greeting1]]', '[[myplugin:greeting2]]', ].join('|||'); // language is only required if server-side here translator.translate(tokens, language, (translated) => { const [greeting1, greeting2] = translated.split('|||'); // etc });This works well, especially when you need to translate from multiple namespaces, but has a fair amount of overhead.
Get translations directly and pick the ones you want, like so // language is required here translator.getTranslations(language, 'myplugin', (translations) => { const { greeting1, greeting2 } = translations; // etc });This works great with single namespaces but with multiple namespaces it gets a little more complicated.
