Talend Studio enables you to access a list of all community components in Talend Exchange that are compatible with your current version of Talend Studio. You can then download and install these components to use them later in the Job designs you carry out in the Studio. From Talend Studio, you can also upload components you have created to Talend Exchange to share with other community users.
A click on the Exchange link on the toolbar of Talend Studio opens the Exchange tab view on the design workspace, where you can find lists of:
components available in Talend Exchange for you to download and install,
components you downloaded and installed in previous versions of Talend Studio but not installed yet in your current Studio,
components you have created and uploaded to Talend Exchange to share with other Talend Community users.
Note that the approach explained in this section is to be used for the above-mentioned components only.
Before you can download community components or upload your own components to the community, you need to sign in to Talend Exchange from your Studio first. If you did not sign in to Talend Exchange when launching the Studio, you still have a chance to sign in from the Talend Exchange preferences settings page. For more information, see Exchange preferences (Talend > Exchange).
The community components available for download are not validated by Talend. This explains why you may encounter component loading errors sometimes when trying to install certain community components, why an installed community component may have a different name in the Palette than in the Exchange tab view, and why you may not be able to find a component in the Palette after it is seemingly installed successfully.
To install community components from Talend Exchange to the Palette of your current Talend Studio:
Click the Exchange link on the toolbar of Talend Studio to open the Exchange tab view on the design workspace.
In the Available Extensions view, if needed, enter a full component name or part of it in the text field and click the fresh button to find quickly the component you are interested in.
Click the view/download link for the component of interest to display the component download page.
View the information about the component, including component description and review comments from community users, or write your own review comments and/or rate the component if you want. For more information on reviewing and rating a community component, see How to review and rate a community component.
If needed, click the left arrow button to return to the component list page.
Click the Install button in the right part of the component download page to start the download and installation process.
A progress indicator appears to show the completion percentage of the download and installation process. Upon successful installation of the component, the Downloaded Extensions view opens and displays the status of the component, which is Installed.
From the Exchange tab view, you can reinstall components you already downloaded and installed in your previous version of Talend Studio or install the updated version of Talend Studio or components in your current Studio.
By default, while you are connected to Talend Exchange, a dialog box appears to notify you whenever an update to an installed community component is available. If you often check for community component updates and you do not want that dialog box to appear again, you can turn it off in Talend Exchange preferences settings. For more information, see Exchange preferences (Talend > Exchange).
To reinstall a community component you already downloaded or update an installed one, do the following:
From the Exchange tab view, click Downloaded Extensions to display the list of components you have already downloaded from Talend Exchange.
In the Downloaded Extensions view, the components you have installed in your previous version of Talend Studio but not in your current Studio have an Install link in the Install/Update column, and those with updates available in Talend Exchange have an Update link.
Click the Install or Update link for the component of interest to start the installation process.
A progress indicator appears to show the completion percentage of the installation process. Upon successful installation, the Downloaded Extensions view displays the status of the component, which is Installed.
To review and rate a community component:
From the Available Extensions view, click the view/download link for the component you want to review or rate to open the community component download page.
On the component download page, click the write a review link to open the [Review the component] dialog box.
Fill in the required information, including a title and a review comment, click one of the five stars to rate the component, and click Submit Review to submit you review to the Talend Exchange server.
Upon validation by the Talend Exchange moderator, your review is published on Talend Exchange and displayed in the User Review area of the component download page.
You can create your own components for use in your Jobs in Talend Studio and upload them to Talend Exchange to share with other Talend Community users. For information on how to create your own components and deploy them in Talend Studio, see How to define the user component folder (Talend > Components).
To upload a component you created to Talend Exchange, complete the following:
From the Exchange tab view, click My Extensions to open the My Extensions view.
Click the Add New Extension link in the upper right part of the view to open the component upload page.
Complete the required information, including the component title, initial version, Studio compatibility information, and component description, fill in or browse to the path to the source package in the File field, and click the Upload Extension button.
Upon successful upload, the component is listed in the My Extensions view, where you can update, modify and delete any component you have uploaded to Talend Exchange.
