Fake Zanata Server

A simple REST server that presents a REST API similar to Zanata Server.


Fake Zanata Server is a tool to support developers who are making apps that communicate with a real Zanata server. It can also be used to try out proposed REST endpoints for Zanata during API design.


Requires Node.js.


To contribute to this server, create a branch or fork with your changes and submit a pull request for review.

Do not commit directly to master - it is not a maintainable practice. I will revert, rewrite or annihilate commits that are not reviewed through a pull request.


Install dependencies:

[prompt]$ npm install

Start the server with the default settings:

[prompt]$ npm start
REST endpoint listening at http://localhost:7878/zanata/rest, with latency 50..500

You can change some settings with command-line flags:

[prompt]$ npm start --port=1234 --latency=1000..5000 --path=rest --alloworigin="http://localhost:9000"
REST endpoint listening at http://localhost:1234/rest, with latency 1000..5000
  • --alloworigin: allowed origin protocol+domain+port for CORS requests, used in CORS preflight responses. Default: http://localhost:8080
  • --debug: true to show debugging information in the console. Default: false
  • --latency: milliseconds to delay each response. Can be a single number, or a range in the form minimum..maximum. Default: 50..500
  • --path: path to prepend to the local portion of each resource URL. Default: zanata/rest
    • --port: any available system port to listen on. Default: 7878

Get resources from any of the endpoints listed under 'Endpoints' below:

[prompt]$ curl http://localhost:7878/zanata/rest/projects
    "id": "tiny-project",
    "defaultType": "File",
    "name": "Tiny Project",
    "description": "A minimal project with a single version containing a single document.",
    "sourceViewURL": null,
    "sourceCheckoutURL": null,
    "links": [{
        "href": "p/tiny-project",
        "rel": "self",
        "type": "application/vnd.zanata.project+json"
    "iterations": null,
    "status": "ACTIVE"
[prompt]$ curl http://localhost:7878/zanata/rest/projects/p/tiny-project
  "id": "tiny-project",
  "defaultType": "File",
  "name": "Tiny Project",

  "sourceViewURL": "source-view-url",
  "sourceCheckoutURL": "source-checkout-url",
  "links": null,
  "iterations": [{
      "id": "1",
      "links": [{
          "href": "iterations/i/1",
          "rel": "self",
          "type": "application/vnd.zanata.project.iteration+json"
      "status": "ACTIVE",
      "projectType": "File"
  "status": "ACTIVE"
[prompt]$ curl http://localhost:7878/zanata/rest/projects/p/tiny-project/iterations/i/1/r
    "name": "hello.txt",
    "contentType": "text/plain",
    "lang": "en-US",
    "extensions": null,
    "type": "FILE",
    "revision": 1


The data available from this mock endpoint will intentionally be minimal, so that it is easy to reason about.

Tiny Project

A minimal project with a single version containing a single document.

  • id: tiny-project
  • version: 1
  • document: hello.txt

Plurals Project

A project that has plurals in its source document. Has a single version and document.

  • id: plurals-project
  • version: 1
  • document: plurals.txt


Here is a list of the available endpoint URLs. Some are experimental URLs for use in development, that are not yet present in the real Zanata server.

Real endpoints

These exist on the real Zanata server

  • Projects, Strings and Translations
    • projects
    • projects/p/{projectSlug}
    • projects/p/{projectSlug}/iterations/i/{versionSlug}
    • projects/p/{projectSlug}/iterations/i/{versionSlug}/r
    • projects/p/{projectSlug}/iterations/i/{versionSlug}/r/{encodedDocId*}
  • Statistics
    • /stats/proj/{projectSlug}/iter/{versionSlug}/doc/{encodedDocId*}

*Note: docId is encoded by replacing / with ,.

Fake endpoints

These do not exist on the real Zanata server, but may be implemented there in the future.

  • locales

    • get list of enabled locales of Zanata instance
    • e.g. [ { "localeId": "en-US", "name": "English"}, { "localeId": "fr", "name": "French"} ]
  • project/{projectSlug}

    • get project information. See: projects/p/{projectSlug}
  • project/{projectSlug}/version/{versionSlug}

    • get project-version information. See: projects/p/{projectSlug}/iterations/i/{versionSlug}
  • project/{projectSlug}/version/{versionSlug}/docs

    • get a list of documents for a project-version. See: projects/p/{projectSlug}/iterations/i/{versionSlug}/r
  • project/{projectSlug}/version/{versionSlug}/doc/{encodedDocId*}

    • get a document of project-version
  • project/{projectSlug}/version/{versionSlug}/locales

    • get a list of the enabled translation locales for a project-version
  • project/{projectSlug}/version/{versionSlug}/doc/{docId}/status/{localeId}

    • get a list of all text flow ids with their status in a given locale
    • may want to allow query parameters for start index and limit, so that simple clients can use paging. Range header fields may be appropriate for this.
    • includes both the numeric database id (id) and the resource id (resId)
    • e.g. [ { id: 1234, resId: "first", status: "translated" }, { id: 1237, resId: "second", status: "fuzzy" }, { id: 1238, resId: "third", status: "untranslated" } ]
  • /stats/project/{projectSlug}/version/{versionSlug}/doc/{encodedDocId*}/locale/{localeId}

    • get words and message statistic of given document in given locale
  • endpoints for getting string details: source, translation, or both

    • paths from root REST url:
      • source?ids={list-of-ids}
      • trans/{localeId}?ids={list-of-ids}
        • {document-path}/translations/{localeId} is already available, but is not quite right for what the editor will use.
      • source+trans/{localeId}?ids={list-of-ids}
    • response will be an object with the ids as keys, and the data as values.
    • data is an object in the form { source: , : } and may exclude one or the other key depending which method is used.
    • these include the full detail for the head revision in a given language of some text flows.
    • may respond with 403 (Forbidden) if the list of ids is too long. The limit should be set at a sufficiently high number as to prevent the editor getting a 403 response in normal operation.
    • numeric ids are used since they pose less challenges with encoding.
      • endpoints under a document resource may be added later that use a list of resIds. The path for such endpoints is purposely very different because resId is only unique within a document, and allowing both id and resId on the same resource could cause a lot of confusion.
  • POST /suggestions?from={sourceLocaleId}&to={transLocaleId}

    • optional query parameter searchType=FUZZY_PLURAL (real server supports other values)
    • if searchType is not specified, the default is FUZZY_PLURAL
    • body should be an array of strings to search for in the source locale, representing the singular and plural forms of a string.
    • an array containing a single string is acceptable.
  • PUT /trans/{localeId}

    • currently only implemented for the 3rd French string in tiny-project
    • save one or more translations, using their database id.
    • body is an array of objects (one per translation)
      • [ { id: , revision: , content: , plurals: [] }, ... ]
    • a translation could be saved individually by adding /{id} to the URL, but this is redundant and will not initially be implemented.
    • response codes:
      • 201 (CREATED) or 200 (SUCCESS) if it was successful
      • 409 (CONFLICT) if revision is not the current version on the server (this check is not done in the current version, so expect only 200).
  • /user

    • get user's information for the current authenticated user, equivalent to /user/{username} with the current user's username.
  • /user/{username}

    • get user's information with given username
    • e.g. { "username" : "username", "email" : "email", "name" : "display name", "gravatarHash" : "gravatar hash" }
  • project/{projectSlug}/permission/{localeId}

    • get user's permission in project under specified locale
    • e.g. { "write_translation" : true, "review_translation" : false }
