Introduction

A week ago, Microsoft officially released the , introducing new awesome features like the Developer Preview of Dynamic Data and the ability to create solutions with beta features by adding –plusbeta to the Yeoman command — among other features.

While it isn’t necessary to update your existing SPFx solutions, you may need to do so (let’s say, because you have an existing solution that needs a feature only available in SPFx 1.5, for example).

Unfortunately, the solution upgrade process between versions of SPFx is often painful.

Thankfully, there is an easy way to do this now!

This article explain a (mostly) pain-free to upgrade your SPFx solution. Waldek explains this process in details, but this is a summary of how to do it.

Office 365 CLI

 

Office 365 CLI is a cross-platform command-line interface (at least, that’s what I think CLI means… I hate acronyms) that allows you to do a lot of things with your Office 365 subscription, on pretty-much any operating system you want to do. (Find out more about Office 365 CLI).

The Office 365 CLI version 1.4.0-beta version introduced a new spfx project upgrade function; It can be used to upgrade an SPFx project.

If you don’t have Office 365 CLI version 1.4.0-beta or above, you’ll need to install it first.  To do so, run the following command:

npm i -g @pnp/office365-cli@next

Analyzing your project

The spfx project upgrade function does not change your project — you’ll need to do this yourself; it analyzes your project and gives you a report telling you exactly what you need to do.

To use it, follow these steps:

• From your command-line, change your current directory to the root of your SPFx project.
• Type the following command:

o365 spfx project upgrade --output md > report.md

Once analysis is completed, open the report.md file that was created in your SPFx project folder.

Upgrading your project

If you really want to all the required changes that the analysis found, you can read the report, but if you’re in a hurry, follow these steps:

• Back-up your project (do I really need to say this?)
• Scroll to the (almost) end of the report.md file and look for the Summary section.
• Copy the code block under the Execute script header and paste it into your console.

  

• Next, find every file in the Modify files section and make the highlighted changes. Pro tip: the report provides a hyperlink to each file that you need to change. Just use CTRL-Click to open the file.

  

Note that you may have multiple updates to make to the same file, but the report will list each update as a separate entry.  The report also pretends that there is nothing else in the file than what it shows in the report. So, for example, if your .yo-rc,json file looks like this before the upgrade:

{
    "@microsoft/generator-sharepoint": {
        "version": "1.4.1",
        "libraryName": "react-calendar-feed",
        "libraryId": "dd42aa00-b07d-48a2-8896-cc2f8c0d3fae",
        "environment": "spo"
     }
}

and the upgrade report tells you to update .yo-rc.json as follows:

{
    "@microsoft/generator-sharepoint": {
        "version": "1.5.0"
    }
}

You’re really supposed to update the .yo-rc.json as follows (change highlighted in bold):

{
    "@microsoft/generator-sharepoint": {
        "version": "1.5.0",
        "libraryName": "react-calendar-feed",
        "libraryId": "dd42aa00-b07d-48a2-8896-cc2f8c0d3fae",
        "environment": "spo"
     }
}

But the next sections in the report will include more changes to the .yo-rc.json file, which — when you’ve made all the changes — will look like this:

{
    "@microsoft/generator-sharepoint": {
        "version": "1.5.0",
        "libraryName": "react-calendar-feed",
        "libraryId": "dd42aa00-b07d-48a2-8896-cc2f8c0d3fae",
        "environment": "spo",
        "isCreatingSolution": true,
        "packageManager": "npm",
        "componentType": "webpart"
     }
}

Once you’ve made all your changes, test your solution and (hopefully) it will work with SPFx 1.5!

Conclusion

You shouldn’t need to upgrade your solution every single time Microsoft releases a new version of SPFx.

If you have to upgrade your solution, however, the Office 365 CLI spfx upgrade project command can save you a lot of time.
