Upgrade SPFx Solutions With Office 365 CLI

In this article, you will learn how to upgrade SPFx solutions with Office 365 CLI.

Overview

 
SharePoint Framework is ever growing. With each of its versions, it releases newer functionality. Upgrading the SPFx solutions each time is a challenge. The manual efforts to upgrade may or may not work. In some cases, we might have to rewrite the code in a newer version.
 
However, Office 365 CLI handles this scenario gracefully and provides a flexible option for developers to upgrade to any new version of SPFx.
 
In this article, we will explore how Office 365 CLI helps to upgrade the SPFx solution to a newer version

Upgrade SPFx Solution to Newer Version

 
We will take an example of SPFx solution (React based Carousel) developed earlier with SPFx drop version of 1.7.1. The previous SPFx solution can be downloaded from here. During this article, we will upgrade this solution to the latest SPFx version 1.8.2 (latest available at the time of writing this article).

Upgrade SPFx Solution to Specific Version

 
In some scenarios, we might not want to upgrade to the latest available SPFx version but maybe to some intermediate version. Office 365 CLI supports this scenario. Use below command to upgrade to any specific version (e.g. 1.8.0 in this case).
  1. o365 spfx project upgrade --toVersion 1.8.0 --output md > report.md   

Downgrade SPFx Solution?

 
No, Office 365 CLI does not allow downgrading the SPFx solution. For example, if your SPFx solution is created using version 1.7.1 then running below command will not downgrade the SPFx solution to 1.5.0.
  1. o365 spfx project upgrade --toVersion 1.5.0 --output md > report.md  
The report will show the message “Error: You cannot downgrade a project”.
