This repository contains a codemod script for use withJSCodeshift.

The codemod replaces calls to Lodash'sget method with the nativeoptional chaining proposal for ECMAScript. This is a novel new way to reliably access deeply nested object properties, and can be used now with@babel/plugin-proposal-optional-chaining. It is important to note that this will currently only work withBabel 7. If you are using Babel 6.x, then you will need to update your project to Babel 7 to use this codemod.

constfoo=get(data,'crate.box.present.wrapping.color');constbar=get(data,'crate.box.present.wrapping.color','green');// 👇 Becomes 👇constfoo=data?.crate?.box?.present?.wrapping?.color;constbar=data?.crate?.box?.present?.wrapping?.color||'green';

npm install -g jscodeshiftgit clone https://github.com/eschaefer/codemod-get-to-optional-member-expressions.gitcd codemod-get-to-optional-member-expressions/jscodeshift -t ./lodash-get-to-optional-member-expressions.js<file(s)>

Use the-d option for a dry-run and use-p to print the output forcomparison.
