gatsby

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:

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.
