gatsby 0.9.0

Babel 6! Require local install of Gatsby! 2500 stars!

on Node.js Yarn

Another release with two nice DX improvements.

Also we hit 2500 stars as I was writing this review 🎉

Babel 6

Gatsby started its life on Babel 5 but Babel 6 is out and stable so we'll upgrade along with the rest of the ecosystem and take advantage of its improved performance and awesome new plugin api.

Gatsby must now be installed as a dependency of the site

The global Gatsby install now defers to the local install of Gatsby (and throws if it can't find one). This means you can build a site and not worry about needing to upgrade it again as Gatsby accumulates breaking changes. This also helps ensure Gatsby works in environments where you don't want a global install e.g. build servers.

Upgrade instructions

• Install Gatsby — npm install --save gatsby
• Install new Babel 6 dependencies (they must be installed locally) — npm install --save babel-plugin-add-module-exports babel-preset-es2015 babel-preset-react babel-preset-stage-1 and npm install --save-dev babel-preset-react-hmre.
• Uninstall old Babel 5 dependencies (if you added any).
• The link function from gatsby-helpers.js was renamed to prefixLink to clarify its purpose.
• Your .babelrc file needs to be upgraded to look like:

{
  "presets": ['react', 'es2015', 'stage-1'],
  "plugins": ['add-module-exports']
}

• If you modified the default Webpack config in gatsby.config.js, this functionality is now moved to gatsby-node.js and instead of using module.exports, export your config modification function as modifyWebpackConfig. See the updated instructions in the README.
• If you were differentiating between pages with content (like .md files) and pages without (like pages/profile.js) by looking for truthy page.data, you'll now need check for truthy page.data.body.
• If your site is under version control, you might want to ignore the new auto-written module .gatsby-context.js.
• rare if you used the rewritePath, onRouteChange hooks in your app.js — app.js is now not supported. Instead you should export rewritePath in gatsby-node.js and onRouteChange in gatsby-browser.js. The function signatures didn't change. These new files will be gaining more functionality in future releases.

That's it! See you in the issue queues :-)
