How to add Draft posts Support to Gatsby blog

Ever encountered a situation where you need to skip some unfinished, unpolished posts while deploying your Gatsby blog?

Gatsby is awesome 💟.

Using modern web technologies, it takes care of a lot of optimizations out of the box.

Unlike traditional CMS like WordPress which gives a lot of features out of the box, in Gatsby, we need to hand pick the features that we need for our blog and build it by ourselves. It’s not bad. It’s cool 😎.

With great power comes great responsibility.

As we have the complete control over adding features to Gatsby, there are lots of ways to achieve a single feature.

In this article, I am gonna walk us through a simpler way to add support for draft posts to your Gatsby blog.

Let’s enhance our blog powered by markdown files to skip all the posts which are marked as draft in it’s frontmatter while building the site.

First of all, pick your first published post and add draft: false. This will make gatsby to create the graphQL schema for markdownRemark with draft field in it, which is needed in while querying.

Add the following filter in every page where you are querying allMarkdownRemark.

    ...
    allMarkdownRemark(
-      sort: { fields: [frontmatter___date], order: DESC }
+      sort: { fields: [frontmatter___date], order: DESC },
+      filter: {frontmatter: {draft: {ne: true}}}
    ) {
    ...

Next, add the following change in the graphql query of createPages method in gatsby-node.js. It will create the draft posts during development phase but skips during the production phase.

...
resolve(
  graphql(
    `{
-      allMarkdownRemark(sort: {fields: [frontmatter___date], order: DESC}, limit: 1000) {
+      allMarkdownRemark(
+       sort: {fields: [frontmatter___date], order: DESC}, 
+         ${
+           process.env.NODE_ENV === 'production' ? 
+           'filter: {frontmatter: {draft: {ne: true}}}' : 
+           ''
+         }
+         limit: 1000
+      ) {
       edges {
        ...

Now in gatsby-config.js file, make the following change to skip draft posts while generating the RSS feed.

...
-  `gatsby-plugin-feed`,
+  {
+     resolve: `gatsby-plugin-feed`,
+     options: {
+       feeds: [
+         {
+           query: `
+           {
+             allMarkdownRemark(
+               limit: 1000,
+               sort: {order: DESC, fields: [frontmatter___date]},
+               filter: {frontmatter: {draft: {ne: true}}}
+             ) {
+               edges {
+                 node {
+                   excerpt
+                   html
+                   fields {
+                     slug
+                   }
+                   frontmatter {
+                     title
+                     date
+                   }
+                 }
+               }
+             }
+           }            
+           `,
+           output: `rss.xml`
+         },
+       ]
+     }
+ },
...

That’s it. Now your blog has support for draft posts. Any post which is marked as draft: true in its front matter will be skipped during the build time and available during the development time.

I haven’t covered every case. But this is applicable to most of the cases.

Once check the list of plugins you use in your gatsby-config.js file. You might be using some other plugins like gatsby-plugin-feed-generator. You would need to configure it’s graphql query accordingly.

Hope I have helped you in adding drafts feature to your Gatsby blog with a minimal effort.
