Transforming const to the configured target environment

[pepicrft]

• I have tried upgrading by running bundle update vite_ruby.
• I have read the troubleshooting section before opening an issue.

Description 📖

When running bin/vite build on this repository, I get the following error that I can't trace back to the root of the issue:

failed to load config from /Users/pepibumur/src/github.com/craftweg/buildify/projects/app/vite.config.ts
error during build:
Error: Build failed with 3 errors:

vite.config.ts:13:0: error: Transforming const to the configured target environment ("es5") is not supported yet
vite.config.ts:15:0: error: Transforming const to the configured target environment ("es5") is not supported yet

For some reason esbuild is trying to parse the tsconfig.json and vite.config.ts file.

Reproduction 🐞

1. Clone this repository
2. cd into projects/app.
3. Install dependencies bundle install && yarn install.
4. Run bin/vite build

Hi @pepibumur!

When asking for help please open a Discussion instead—I intend to use Issues for problems in the library only 😃

Following the settings in tsconfig.json is a feature of esbuild.

es5 is now considered an old dialect and it's not well supported in esbuild, so it won't transpile the es6 const to its es5 equivalent.

Since all modern browsers support es6 and more recent dialects, it's safe to target es6 instead, which you already did, cool!

Thanks @ElMassimo and sorry for not posting it in the right place. Changing it to es6 made it pass.
