How to upgrade from 2.8.4 to 4.3.0?

Parse Server 📡
1

Hi everyone!

I have an app that uses Parse Server 2.8.4… because it is too outdated, I want to upgrade it to the latest version. How exactly do I do that? I have no idea what I need to do!

I also understand that many things have changed since the version I’ve got. Is the structure now also different?

Could someone guide me through this?

We offer a Parse Server Migration Guide that should offer a good first read when looking at how to migrate.

For most deployments, the main work is refactoring Cloud Code. Parse Server moved away from chained JavaScript promises to async/await. In addition to the guide mentioned above, there are numerous resources available online about how JavaScript async/await works and what to consider.

Then there may be some changes in terms of APIs and methods, which usually make up the smaller part of the migration effort.

In general, we suggest to take a look at the change log from the current version (2.8.4) up to the target version (4.3.0) to see what which changes may impact your deployment specifically.

Hello @Manuel and thank you for responding!

I checked the migration guide and it does explain how to migrate the cloud code… how do I upgrade the actual Parse Server though?

After parse server v3, cloud code has a new syntax. You need to refractor your cloud code. Also I assume your mongodb database version is also old. You may need to upadte mongodb version to newer version

I checked it and I have Nodejs v8.12.0 and MongoDB v4.0.2. I think it’s ok, right?

Yes you should be fine.

Minimum mongodb version for parse is 3.6 (see docs)

But if you can update nodejs to 12 it would be be better I guess. I’m using node12 with parse 4.2.0 and 4.3.0. And works just fine

It depends on your deployment. If you look at the parse server example, you would follow these steps:

  1. In package.json change dependencies.parse-server to 4.3.0.
  2. Delete package-lock.json and node_modules folder.
  3. Run npm install.
  4. Run / deploy Parse Server as you usually would.

Among other logs, I got this;

Should I be worried or is it expected?

I too am in the process of upgrading from 2.8.4 and discovered that the link to the migration guide referenced here is broken.

@adammlevy I’ve updated the link, thanks for pointing this out.

These many-years-old links are broken because the file is not anymore on the alpha branch. To access the file, you need to go back in time when the file existed by selecting an old version tag on the GitHub page, then you will see the file. For example, there is a link in the Parse Server 3 migration guide you mentioned that points to the Parse JS SDK 2.0 migration guide, that also does not exist anymore. If you select the version tag 3.0.0 in the Parse JS SDK repository then you can access the file: Parse-SDK-JS/2.0.0.md at 3.0.0 · parse-community/Parse-SDK-JS · GitHub.
