In the end, on my project we didn’t solve this by adding logic to the rule. This is actually quite a tricky problem to solve, as there aren’t really any uniquely identifying features of a column definition, other than its context. We don’t actually do a check to see if this is an array of column definitions. It can be quite easy to provide a false positive, or a false negative from your linting rule if you haven’t considered all the code that might be going through it.įor example, with this rule we just wrote, we will throw an error for any array containing objects without a colId or field property. Invalid const columnDefinitions = [ ) Step 5 - Think About Edge Cases This unique ID is what I wanted to enforce using a linting rule. Instead of a field property, you should provide a colId property for the column ID. By default, the field property will be used for the column ID. In order for some features of AG Grids to work, each column must have a unique ID. In some situations, instead of a field property you use a valueGetter property to compute the value for the cell. headerName is the name of the column, field is the property on the model object to pull A basic column definition declares the properties headerName and field. In order to use the grid, you define a list of column definitions In my project, we use AG Grids to display tables of data with functionality such as filtering and row-grouping. To start with, quantify the aim of the rule you want to write, and then write some code examples which would pass or fail the rule you want to write. Which I will use to demonstrate the process of creating an ESLint rule. With some help from a colleague I managed to write a couple of rules to enforce in my codebase, To do this, but found I was a bit confused when it came to actually writing the rule. How to add a custom ESLint package to the project, and import its rules (and even publish it online). Of course my initial reaction was to google it, and I found lots of helpful articles explaining For a request to be blocked by the custom pattern, all parameters in the custom pattern must appear in the request.I recently wanted to add a custom ESLint rule to my JavaScript codebase. In case using Parameters option, parameter name is mandatory and parameter value is optional. Parameters relate to both query and body parameters. Only if the Enforcer matched the pattern in the selected expected location, it would search also for the Parameters. Parameters – Can be zero or more pairs of param names. When a header name is specified, the “headers” scanning zone must be specified as well. HeaderName – In case you want to search the pattern in a specific header. true – means Pattern is a regular expression. Pattern – pattern value which can be literal or regular expression. The Pattern will be searched in the Parameter name or the Parameter value. Parameters - Can be a Query Parameters or a Body Parameters (JSON, XML, multipart/form-data, etc.). Body - The Pattern will be searched in the request body (for any Content-type).ĭ. The Pattern will be searched in the Header value.Ĭ. URI - URI includes the Path, the Filename, the parameters name and the parameters value.ī. If you want to search the pattern in the URI only you should write. ĮxpectedLocations is related to the patterns only. ID – A unique ID, can contains digits, alphabet letters and ‘-‘ char.ĮxpectedLocations – Scanning zones in the HTTP request, consists of four zones. Waas-custom-rules-configmap-object: validate Under ‘ 'custom_rules_conf.json’ add the following instead of the “” chars: Run the command kubectl edit cm -n kwaf waas-custom-rules-configmap To add a customer rule via CLI by modifying ConfigMap: By default the suggested scanning zone will be where the pattern was found at:Īdding a custom rule is supported starting KWAAP 1.5. Go to Forensics->Security Event and click the Exclude button on the relevant Signature Engine event:įrom the pop up window choose the scanning zone to exclude the pattern from. If the rule is excluded for a header, it can be defined for a specific header name and even define the header name as regular expression (in Regex check box).Įxcluding specific signature using the UI Preprocessors and decorators do not support nested visitors. decorators Decorators dont execute for the lint command. There are three main differences between preprocessors, rules and decorators. Once adding a Rule ID you can choose the scanning zone that the rule will be excluded from – URI, Body, Parameters, Headers or “ALL” which stands for all scanning zones. Extend the CLI through the use of custom plugins. Signature Engine protection has three optional states – Active (block), Passive (report only) or Bypass (disable).Įxcluding specific signature is available directly in the Signature Engine configuration form or as an exception definition from the logs in the Forensics view.
