Zotero Translation Server v2

The Zotero translation server lets you use Zotero translators without the Zotero client.

Installation

git clone --recurse-submodules https://github.com/zotero/translation-server
cd translation-server
npm install

Running via Node.js

npm start

Running via docker

Production

Pull from Docker Hub and run as a background process:

docker pull zotero/translation-server
docker run -d -p 1969:1969 --rm zotero/translation-server

Development

Build from local repo and run in foreground:

docker build -t translation-server .
docker run -ti -p 1969:1969 --rm translation-server

Running on AWS Lambda

translation-server can also run on AWS Lambda and be accessed through API Gateway. You will need the AWS SAM CLI to deploy the server.

Copy and configure config file:

cp lambda_config.env-sample lambda_config.env

Test locally:

./lambda_local_test lambda_config.env

Deploy:

./lambda_deploy lambda_config.env

You can view the API Gateway endpoint in the Outputs section of the CloudFormation stack in the AWS Console.

Proxy Support

You can configure translation-server to use a proxy server by setting the HTTP_PROXY and HTTPS_PROXY environment variables:

HTTP_PROXY=http://proxy.example.com:8080 HTTPS_PROXY=http://proxy.example.com:8080 npm start

If your proxy server uses a self-signed certificate, you can set NODE_TLS_REJECT_UNAUTHORIZED=0 to force Node to ignore certificate errors.

It’s also possible to opt out of proxying for specific hosts by using the NO_PROXY variable. See the Node request library documentation for more details.

Running tests

npm test

Endpoints

Web Translation

Retrieve metadata for a webpage:

$ curl -d 'https://www.nytimes.com/2018/06/11/technology/net-neutrality-repeal.html' \
   -H 'Content-Type: text/plain' http://127.0.0.1:1969/web

Returns an array of translated items in Zotero API JSON format

Retrieve metadata for a webpage with multiple results:

$ curl -d 'https://www.ncbi.nlm.nih.gov/pubmed/?term=crispr' \
   -H 'Content-Type: text/plain' http://127.0.0.1:1969/web

Returns 300 Multiple Choices with a JSON object:

{
	"url": "https://www.ncbi.nlm.nih.gov/pubmed/?term=crispr",
	"session": "9y5s0EW6m5GgLm0",
	"items": {
		"u30044970": {
			"title": "RNA Binding and HEPN-Nuclease Activation Are Decoupled in CRISPR-Cas13a."
		},
		"u30044923": {
			"title": "Knockout of tnni1b in zebrafish causes defects in atrioventricular valve development via the inhibition of the myocardial wnt signaling pathway."
		},
		// more results
	}
}

To make a selection, delete unwanted results from the items object and POST the returned data back to the server as application/json.

Search Translation

Retrieve metadata from an identifier (DOI, ISBN, PMID, arXiv ID):

$ curl -d 10.2307/4486062 -H 'Content-Type: text/plain' http://127.0.0.1:1969/search

Export Translation

Convert items in Zotero API JSON format to a supported export format (RIS, BibTeX, etc.):

$ curl -d @items.json -H 'Content-Type: application/json' 'http://127.0.0.1:1969/export?format=bibtex'

Import Translation

Convert items in any import format to the Zotero API JSON format:

$ curl --data-binary @data.bib -H 'Content-Type: text/plain' http://127.0.0.1:1969/import
