Nextcloud lint plugin for ESLint. This plugin provides a set of rules in order to check compliance of your app to the Nextcloud JavaScript API.

It is recommended to configure your app to use @nextcloud/eslint-config in advance. Then, this plugin is integrated automatically, but you profit also from the common Nextcloud coding standard.


You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install @nextcloud/eslint-plugin:

$ npm install @nextcloud/eslint-plugin --save-dev


Add plugin:nextcloud/recommended to the extends section of your .eslintrc configuration file in order to use all recommended options (load estlint-plugin-nextcloud, add Nextcloud environment and add recommended rules):

    "extends": [

Alternatively, you can activate only those parts that you want to use. In this case, you have to add nextcloud to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

    "plugins": [

Add the Nextcloud environment if you want to use global variables defined by Nextcloud server.

    "env": {
        "nextcloud/nextcloud": true,

Configure the rules you want to use under the rules section.

    "rules": {
        "nextcloud/no-deprecations": "warn",
        "nextcloud/no-removed-apis": "error",

Limit the Nextcloud version to report

By default all removed or deprecated API is reported, but if your app targets an older version of Nextcloud then you can limit the reported issues to changes before and with that version.

For example you target Nextcloud 25 and you use OC.L10n which was deprecated with Nextcloud 26. To disable reporting that deprecation you can set the target version to 25:

    "rules": {
        "nextcloud/no-deprecations": ["warn", { "targetVersion": "25.0.0" }],
        "nextcloud/no-removed-apis": ["error", { "targetVersion": "25.0.0" }],

It is also possible to detect that your supported Nextcloud version from your appinfo/info.xml (max-version of your nextcloud dependency):

    "rules": {
        "nextcloud/no-deprecations": ["warn", { "parseAppInfo": true }],
        "nextcloud/no-removed-apis": ["error", { "parseAppInfo": true }],
