Steven	2b57e12ad3	[build-utils] Refactor framework prefixed env vars into shared function (#8166 ) This consolidates the logic to get the framework-specific prefixed System Environment Variables into a single shared function so each builder can reuse the same function. - Related to #7009 - Related to #8306 In the future, this feature could be added to any other missing builders as well as `vc dev` but we'll save that for a new PR.	2022-08-05 00:51:52 +00:00
Nathan Rajlich	c4e94ad03f	[cli] Always set `BROWSER=none` env var for frontend dev server in `vc dev` (#8326 ) Previously `vc dev` would only set this env var for "create-react-app" Framework preset, but other frameworks do the "auto-open browser window" behavior as well, and respect this env var (Docusaurus, specifically). So always set the `BROWSER=none` env var regardless of which framework preset is selected. Also simplifies the code since this was the only place `frameworkSlug` property was being used.	2022-08-04 21:49:14 +00:00
