Generating Pages From Contentful

I would use environment variables in your gatsby-config.js to hide your contentful API accesstoken and spaceid. This can be done by adding this to the top of the file,

require("dotenv").config({
  path: `.env.${process.env.NODE_ENV}`,
})

and then populate the .env file and use the variables like,

{
      resolve: `gatsby-source-contentful`,
      options: {
        spaceId: `${process.env.CONTENTFUL_SPACEID}`,
        accessToken: `${process.env.CONTENTFUL_ACCESS_TOKEN}`,
      },
    },
