Best approach for upgrading a template?

[niftylettuce]

Let's say someone upgrades to a newer version of a CLI of Sao, e.g. lad (see https://github.com/ladjs/lad) via npm install -g lad@latest. They then want to upgrade their template. What would be the best approach? Just a git clone and then apply the diff between template directory and the user's project dir?

For an already generated project it's hard to upgrade automatically since you may have changed many files 🤔

@egoist Maybe we do something like this https://react-native-community.github.io/upgrade-helper/?from=0.59.8&to=0.60.3? and https://facebook.github.io/react-native/docs/upgrading

Also https://github.com/react-native-community/cli/blob/48626dd239e01d9d060f0d47661013610a0dcd0a/packages/cli/src/commands/upgrade/upgrade.ts and https://github.com/react-native-community/cli/blob/48626dd239e01d9d060f0d47661013610a0dcd0a/packages/cli/src/commands/upgrade/__tests__/upgrade.test.ts

It would be incredible for sao to have a package (possibly one even built-in) that lets you do this by plugging the package into your CLI.

This would be the BEST feature for Sao by far compared to ANY other template/scaffolding too.

[niftylettuce]

Also would gladly donate to you to help build something like this 😄

I found your Patreon, now a supporter.

Thanks, I'll take a look at the react-native solution, this is definitely a missing feature for every scaffolding tool.

[niftylettuce]

Let me know!

Codemods would work well. JSCodeShift is a solid tool. Good example usage with jest.

[niftylettuce]

Would be awesome to have this 🙌

I am awarding a $200 bug bounty for this issue.

[egoist]

I will create a website like https://react-native-community.github.io/upgrade-helper to show the diffs between two versions of a generator

@egoist Hey! I also shared this with @shaunwarman - but I think having a CLI tool like this would be great:

https://github.com/willmendesneto/update-yeoman-generator/blob/9946691c89a70a5916b929c7c2f38b26a9536445/lib/run.js

[egoist]

Yes, a separate CLI tool like that is also planned.

[niftylettuce]

Any update here @egoist ?

[shaunwarman]

Checking in again @egoist , I should have bandwidth to dive in and help, but unsure if you have some ideas / todos for this new CLI tool
