npm install @textlint/types


import { TextlintSourceCode, TextlintSourceCodeArgs, TextlintSourceCodeLocation, TextlintSourceCodePosition, TextlintSourceCodeRange } from "@textlint/types";
import { TextlintRuleContextFixCommand } from "@textlint/types";
import { TextlintRuleContextFixCommandGenerator } from "@textlint/types";
import { TextlintRuleError, TextlintRuleErrorPadding, TextlintRuleReportedObject } from "@textlint/types";
import { TextlintRuleSeverityLevel } from "@textlint/types";
import { TextlintRuleContext, TextlintRuleContextArgs, TextlintRuleContextReportFunction, TextlintRuleContextReportFunctionArgs } from "@textlint/types";
import { TextlintRuleOptions } from "@textlint/types";
import { TextlintRuleReporter, TextlintFixableRuleModule, TextlintRuleModule, TextlintRuleReportHandler } from "@textlint/types";
import { TextlintFilterRuleContext, TextlintFilterRuleShouldIgnoreFunction, TextlintFilterRuleShouldIgnoreFunctionArgs } from "@textlint/types";
import { TextlintFilterRuleModule, TextlintFilterRuleOptions, TextlintFilterRuleReporter, TextlintFilterRuleReportHandler } from "@textlint/types";
import { TextlintPluginCreator, TextlintPluginOptions, TextlintPluginProcessor, TextlintPluginProcessorConstructor } from "@textlint/types";


Occur incompatible types between @textlint/types and other module like textlint-rule-helper

You should check if your @textlint/types dependencies is duplicated.

@textlint/types should be deduped.

npm ls @textlint/types

If your dependencies is duplicated, you should update modules that are depended on @textlint/types.

Versioning Policy

@textlint/types is not semantic versioning. Because, This library provide only TypeScript definition.

It is hard that we follow a semantic versioning.
