In-context Setup


Crowdin In-Context works with the help of a one-line Javascript snippet and pseudo-language package. It creates a pseudo-language package based on the localization files uploaded to your project, which later will be integrated into your application as an extra localization language.

Integrated pseudo-language contains some special identifiers instead of the original texts, thus when switching your app to that language, all of the labels are converted to the special identifiers. Javascript searches for those identifiers and replaces them with editable labels. So, the In-context page of your web app will look the same as your application, with the only difference that translatable strings will be editable.

In-Context View

Translations are made directly in the app, with no need to open the Editor. As a simplified version of Crowdin Editor will be displayed, with all the functionality (TM, machine translation, approve/vote option, comments, terms) provided. Thus, it’s easier to make and review translations, as that can be previewed in a real context.

In-Context Editor


There are two common approaches to integrate Crowdin In-Context with your application:

  • Staging or translation environment. If you are not planning to invite your end-users to help with translations or not considering to use a “translation mode” in your production application, integrating Crowdin In-Context to your staging or dedicated translation app environment would be a good solution.
  • Production environment. Crowdin In-Context does not require any code changes in your application, so it can be used even on production. You decide how to turn it on and which segment of users will use it. The most common use cases are the following:
    • you can create a mirror website, that is a complete copy of your application, but under a different URL (for example, instead of it can be, where translators will make translations like if it was your real application.
    • you can also add In-context as an extra language. So, when translators open your application they will be able to choose one extra language from the list, which will open In-context for them.

Follow the integration setup guide in your Crowdin project to set up In-context. The guide can be found in the left-hand panel in your project, under Resources > Integrations & API.

After the integration is successfully set up and you refreshed your application, you should be able to see the invitation dialog and Crowdin login box.

Optional Parameters

You can add these parameters to _jipt array in the configuration snippet.

Texts Preloading

_jipt.push(['preload_texts', true]);

Speeds up dynamic content displaying within the In-Context tool by preloading all source strings. Automatically disabled for the large projects (5000+ strings). Acceptable values: true, false.

Translation Button Always Visible

_jipt.push(['touch_optimized', true]);

This option is enabled on touchscreens by default and makes the translation button next to each translatable string permanently visible, as opposed to showing on hover. Acceptable values: true, false.

Before Commit Callback

_jipt.push(['before_commit', function(source, translation, context, language_code) {
  return status_obj;

Function to validate the suggestion before committing.

sourceSource text
translationTranslation text
contextSource string context
language_codeTarget language code (language codes)
Return Values
status_obj Object. The status_obj.status may be "ok", "error" or "corrected". In case of error, status_obj.message contains error description. When status is "corrected", status_obj.correction contains the corrected translation

Before DOM Insert Callback

_jipt.push(['before_dom_insert', function(text, node, attribute) {
  return 'text';

Function to transform the string before it gets inserted into the DOM.

textString for insertion
DOM element in which the text must be inserted. May be omitted if the text does not have a target element (text inside the browser's pop-ups)
The attribute of DOM element, if the text is part of an attribute
Return Values
textString for insertion
falseIf the function returns false, DOM will not be updated

Close the In-Context Overlay Callback

_jipt.push(['escape', function() {
  window.location.href = "";

If defined, users can close In-Context overlay if they don’t want to translate. Implement this feature on your side. It must change the app’s language or redirect from translation environment to the production app, depending on the In-Context integration approach.
