programatically create page from plugin

create-pages.js

const path = require(`path`)
const slash = require(`slash`)

module.exports = ({ graphql, boundActionCreators }) => {
  const { createPage } = boundActionCreators
  const postTemplate = path.resolve(`${__dirname}/templates/changelog.js`)


  createPage({
    // Each page is required to have a `path` as well
    // as a template component. The `context` is
    // optional but is often necessary so the template
    // can query data specific to each page.
    path: `/changelog/`,
    component: slash(postTemplate),
    context: {
      entries: []
    },
  })
