Tiny Tips for Gatsby Incremental Builds on Netlify

May 16, 2020  |  2 min read

Recently, Netlify started supporting Gatsby’s incremental builds. It remarkably reduces the build time by caching the previous build! The official blog says this feature is easy to enable, but I came into an error at the first trial. I write this post for those who are in trouble with the same error.

Environment

$ gatsby --version
Gatsby CLI version: 2.8.29
Gatsby version: 2.21.33

$ node --version
v12.16.2

$ npm --version
6.14.4

Error

I just followed the instruction in the official blog. I saw no errors in the development environment, so I pushed the code, and got this error on Netlify.

How to Solve

This error was totally unfamiliar to me. Searching by the error message did not help.

Since the error was happning in netlify.toml, I checked the file and went to the official repository of netlify-plugin-gatsby-cache.

It tells us to add the following lines in netlify.toml.

[build]
  publish = "public"

[[plugins]]
  package = "netlify-plugin-gatsby-cache"

The first two lines are critical. Adding them solved my problem. The problem was that I didn’t include the first two lines because I created netlify.toml just when I read the blog.
