Installation

From the command line run:

npm install @saws/translate

Then add the TranslateService to your saws.js file.

Development

When running your SAWS application in development, this service will do nothing. Important to note that the Translate library will still hit AWS's translation services when running in development.

Deployment

When you deploy a TranslateService it will not create any resources in AWS. This service primarily functions as a way to ensure any dependant services have the right permissions set up.

Services

@saws/translate includes one service, TranslateService.

TranslateService

You can require the TranslateService and use it in your saws.js file like so:

const { TranslateService } = require('@saws/translate/translate-service')

// will exclusively be used as a dependency to other services
const translate = new TranslateService({
  name: 'translate-service',
})

The TranslateService constructor accepts the following options:

name: string

The name of your service. This should be unique across all of your services.

dependencies: ServiceDefinition[]

An array of all of the other services this service depends on. This will ensure that permissions, environment variables, and execution order are all set up.

When used as a dependency

When a TranslateService is used as a dependency, it will not attach any environment variables to the dependant service.

Libraries

@saws/translate includes a Translate class that can be used to get machine translations from AWS's translation services.

Translate

The Translate class can be used as follows:

import { Translate } from '@saws/translate/translate-library'

const client = new Translate()

const result = await client.translateText('Some text', sourceLanguage, targetLanguage)

translateText(text: string, sourceLanguage: string, targetLanguage: string): Promise<string>

This function will use AWS's translation services to perform a machine translation of the provided text from the source language to the target language.
