ESLint plugin for linting n8n nodes.
Install this plugin:
npm i -D eslint-plugin-n8n-nodes-base
Create an ESLint configuration file and decide how to set up the plugin.
If you specify only the plugin, all rules in the plugin are disabled by default and must be individually enabled:
{
plugins: [ "eslint-plugin-n8n-nodes-base" ],
rules: {
"n8n-nodes-base/node-param-array-type-assertion": "warning",
"n8n-nodes-base/node-param-default-wrong-for-collection": "error"
}
}
If you specify both the plugin and a config, all config rules are enabled by default and must be individually disabled:
{
plugins: [ "eslint-plugin-n8n-nodes-base" ],
extends: [ "plugin:n8n-nodes-base/nodes" ],
rules: {
"n8n-nodes-base/node-param-array-type-assertion": "off",
"n8n-nodes-base/node-param-default-wrong-for-collection": "off"
}
}
| Config | Content |
|---|---|
nodes | Ruleset for n8n nodes |
credentials | Ruleset for n8n credentials |
community | Ruleset for package.json in n8n community package |
In the community ruleset, the five *-still-default rules allow you to define your own default values:
{
plugins: [ "eslint-plugin-n8n-nodes-base" ],
extends: [ "plugin:n8n-nodes-base/nodes" ],
rules: {
"n8n-nodes-base/community-package-json-author-name-still-default": [
"error",
{ authorName: "Neil Armstrong" }, // user-defined default
],
}
