gulp-tslint

TypeScript linter plugin for Gulp.

First install gulp-tslint

npm install --save-dev gulp-tslint

Usage:

const tslint = require('gulp-tslint');

gulp.task('tslint', function(){
      return gulp.src('source.ts')
        .pipe(tslint())
        .pipe(tslint.report('verbose'));
});

tslint.json is attempted to be read from near the input file. It must be available or supplied directly through the options.

The output (stringified JSON) is added to file.tslint.output. You can output the errors by using reporters. There are five default reporters:

• 'json' prints stringified JSON to console.log.
• 'prose' prints short human-readable failures to console.log.
• 'verbose' prints longer human-readable failures to console.log.
• 'full' is like verbose, but displays full path to the file
• 'msbuild' for Visual Studio

Reporters are executed only if there is at least one failure.

If there is at least one failure a PluginError is emitted after execution of the reporters:

[gulp] Error in plugin 'gulp-tslint': Failed to lint: input.ts

You can prevent emiting the error by setting emitError in report options to false.

gulp.task('invalid-noemit', function(){
    return gulp.src('input.ts')
        .pipe(tslint())
        .pipe(tslint.report('prose', {
          emitError: false
        }));
});

You can summarize the gulp error message to the number of errors by setting summarizeFailureOutput in report options.

gulp.task('invalid-noemit', function(){
    return gulp.src('input.ts')
        .pipe(tslint())
        .pipe(tslint.report('prose', {
          summarizeFailureOutput: true
        }));
});

You can use your own reporter by supplying a function.

/* output is in the following form:
 * [{
 *   "name": "invalid.ts",
 *   "failure": "missing whitespace",
 *   // Lines and characters start from 0
 *   "startPosition": {"position": 8, "line": 0, "character": 8},
 *   "endPosition": {"position": 9, "line": 0, "character": 9},
 *   "ruleName": "one-line"
 * }]
 */
const testReporter = function (output, file, options) {
    // file is a reference to the vinyl File object
    console.log("Found " + output.length + " errors in " + file.path);
    // options is a reference to the reporter options, e.g. including the emitError boolean
};

gulp.task('invalid-custom', function(){
    return gulp.src('input.ts')
        .pipe(tslint())
        .pipe(tslint.report(testReporter));
});

tslint.json can be supplied as a parameter by setting the configuration property.

gulp.task('tslint-json', function(){
    return gulp.src('input.ts')
        .pipe(tslint({
            configuration: {
              rules: {
                "class-name": true,
                // ...
              }
            }
        }))
        .pipe(tslint.report('prose'));;
});

Report limits

You can optionally specify a report limit in the .report options that will turn off reporting for files after the limit has been reached. If the limit is 0 or less, the limit is ignored, which is the default setting.

gulp.task('tslint', function(){
    return gulp.src(['input.ts',])
        .pipe(tslint())
        .pipe(tslint.report('prose', {
            reportLimit: 2
        }));
});

Specifying the tslint module

If you want to use a different version of tslint, you can supply it with the tslint option.

npm install tslint@next

.pipe(tslint({
    tslint: require('tslint')
}))

All default tslint options

const tslintOptions = {
    configuration: {},
    rulesDirectory: null,
    tslint: null
};

All default report options

const reportOptions = {
    emitError: true,
    reportLimit: 0,
    summarizeFailureOutput: false
};
