Gatsby wordpress reading time

[pradtv]

How to calculate the reading time of posts using the gatsby WordPress plugin?

[PsyGik]

Simplest implementation:

npm install reading-time

const readingTime = require('reading-time');

const entityWithReadingTime = ({content, ...rest}) => ({
  content,
  readingTime: content != null && readingTime(content),
  ...rest
});

{
  resolve: `gatsby-source-wordpress`,
  options: {
    // ...
    normalizer: ({entities}) => entities.map(entityWithReadingTime)
  }
}

@PsyGik Where to write the following code?

const readingTime = require('reading-time');

const entityWithReadingTime = ({content, ...rest}) => ({
  content,
  readingTime: content != null && readingTime(content),
  ...rest
});

You can

• keep it in gatsby.config.js or
• write it in another file and import it in gatsby.config.js.

I'd use the latter option, keeps the config file clean and one can write proper tests
