eslint unexpected top-level property

This method accepts four arguments: The verify() method returns an array of objects containing information about the linting warnings and errors. Fixes will not be automatically applied to the files, even if you set fix: true when constructing the CLIEngine instance.

I posted this and now I am getting this error: ESLint configuration in .eslintrc is invalid: - Unexpected top-level property "import/no-extraneous-dependencies". Thanks in advance. You can pass filesystem-style or glob patterns to ESLint and have it function properly. In order to achieve this, ESLint must resolve non-glob patterns into glob patterns before determining which files to execute on. I was writing a code to access webcam, click a picture through my react app or browse and upload the picture from your files. The resolveFileGlobPatterns() methods uses the current settings from CLIEngine to resolve non-glob patterns into glob patterns. Note: Also available as a static function on CLIEngine. To apply fixes to the files, call outputFixes. I tried resolving this error too but could not find anything helpful. ] Retrieves a formatter, which you can then use to format a report object.

Please note the AST also should be parsed from stripped text. Once you get a report object, its up to you to determine how to output the results. Value of codeLines will be The top-level report object has a results array containing all linting results for files that had warnings or errors (any files that did not produce a warning or error are omitted). You can create a new instance of SourceCode by passing in the text string representing the code and an abstract syntax tree (AST) in ESTree format (including location information, range information, comments, and tokens): The SourceCode constructor throws an error if the AST is missing any of the required information. // Deprecated: see "please note" paragraph below. Loads a plugin from configuration object with specified name. The argument is either the name of a built-in formatter: or the full path to a JavaScript file containing a custom formatter. If you want to lint one or more files, use the executeOnFiles() method. Heres an example: The return value is an object containing the results of the linting operation. Heres an example: The information available for each linting message is: Please note: the source property will be removed from the linting messages in an upcoming breaking release. Important: You must pass in the results property of the report. The purpose of the Node.js API is to allow plugin and tool authors to use the ESLint functionality directly, without going through the command line interface. "var a = 1;", */. Checks if a given path is ignored by ESLint. Questions and posts about frontend development in general are welcome, as are all posts pertaining to JavaScript on the backend. Name can include plugin prefix (eslint-plugin-). For resolving this, I ran the suggested commands but the issue persisted and I kept getting the same error. It doesnt do any filesystem operations, it simply parses and reports on the code. Heres an example: The report returned from executeOnText() is in the same format as from executeOnFiles(), but there is only ever one result in report.results. Function name `bar` should match variable name `foo`, // lint the supplied text and optionally set, // a filename that is displayed in the report. The linter will assume that the text is a file in the current working directory, and so will still obey any .eslintrc and .eslintignore files that may be present. to search all JavaScript files in the current directory. Please note: the source property will be removed from the linting messages returned in messages in an upcoming breaking release. Heres an example: If you want to retrieve a configuration object for a given file, use the getConfigForFile() method. You can also omit the argument to retrieve the default formatter. This object will read the filesystem for configuration and file information but will not output any results. The available options are: In this code, a new CLIEngine instance is created that sets two environments, "browser" and "mocha", disables loading of .eslintrc and package.json files, and enables the semi rule as an error. If the operation ends with a parsing error, you will get a single message for this file, with fatal: true added as an extra property. Instead, it allows you direct access to the important information so you can deal with the output yourself. Heres an example of a report object: You can also pass fix: true when instantiating the CLIEngine in order to have it figure out what fixes can be applied. For using react-html5-camera-phot and grommet I was getting the error: import/no-extraneous-dependencies@ error. This is a static function on CLIEngine. Copyright JS Foundation and other contributors. The SourceCode constructor strips Unicode BOM. Please if you can tell me what I am doing wrong, itll be very helpful! // var formatter = cli.getFormatter("compact"); // var formatter = cli.getFormatter("./my/formatter.js"); // get the default formatter by calling the static function. The SourceCode type represents the parsed source code that ESLint executes on. To return a warning instead, call the method with true as the optional third parameter. This is a static function on SourceCode that is used to split the source code text into an array of lines. In particular, the linter object does not process configuration objects or files. Passing in report directly will result in an error. It can be used to filter out all the non error messages from the report object. This method accepts one argument, a file path, and returns an object represented the calculated configuration of the file. While ESLint is designed to be run on the command line, its possible to use ESLint programmatically through the Node.js API. "var b = 2;"

You can then call methods on cli and these options will be used to perform the correct action. Press J to jump to the feed. If you depend on this property, you can still use the getSourceCode method described below to get the line of code for each message. [ Only those parts that are specifically mentioned in this document are approved for use and will remain stable and reliable. Press question mark to learn the rest of the keyboard shortcuts.

Therefore to remove these errors i went through stack overflow, and got a solution that suggested to post import/no-extraneous-dependencies": ["error", {"devDependencies": false, "optionalDependencies": false, "peerDependencies": false}] in my .eslintrc file.

Anything left undocumented is unstable and may change or be removed at any point. You can also get an instance of the SourceCode object used inside of linter by using the getSourceCode() method: In this way, you can retrieve the text and AST used for the last run of linter.verify(). If a filename in the optional second parameter matches a file that is configured to be ignored, then this function returns no errors or warnings. This is a static function on CLIEngine that is used to output fixes from report to disk. This method accepts a single argument, which is an array of files and/or directories to traverse for files.

You can retrieve linter like this: The most important method on linter is verify(), which initiates linting of the given text. Each file result includes: The top-level report object also has errorCount and warningCount which give the exact number of errors and warnings respectively on all the files. Note: Use undocumented parts of the API at your own risk. This subreddit is for anyone who wants to learn JavaScript or help others do so. If you depend on this property, you should now use the top-level source or output properties instead. You can get a reference to the CLIEngine by doing the following: The CLIEngine is a constructor, and you can create a new instance by passing in the options you want to use. The linter object does the actual evaluation of the JavaScript code. It does by looking for files that have an output property in their results. Its used internally in ESLint and is also available so that already-parsed code can be used. Heres an example: Once you have the configuration information, you can pass it into the linter object: If you already have some text to lint, then you can use the executeOnText() method to lint that text. Pass an array of patterns that might be passed to the ESLint CLI and it will return an array of glob patterns that mean the same thing. The primary Node.js API is CLIEngine, which is the underlying utility that runs the ESLint command line interface. Heres an example: /* You can pass the same values as you would using the ESLint command line interface, such as "."
