To solve “[tslint] ‘ should be ” (quotemark)” when developing spfx webpart using visual studio code, do these:
- open config/tslint.json
- add
{
“$schema”: “https://dev.office.com/json-schemas/core-build/tslint.schema.json”,
// Display errors as warnings
“displayAsWarning”: false,
// The TSLint task may have been configured with several custom lint rules
// before this config file is read (for example lint rules from the tslint-microsoft-contrib
// project). If true, this flag will deactivate any of these rules.
“removeExistingRules”: true,
// When true, the TSLint task is configured with some default TSLint “rules.”:
“useDefaultConfigAsBase”: false,
// Since removeExistingRules=true and useDefaultConfigAsBase=false, there will be no lint rules
// which are active, other than the list of rules below.
“lintConfig”: {
// Opt-in to Lint rules which help to eliminate bugs in JavaScript
“rules”: {
“class-name”: false,
“export-name”: false,
“forin”: false,
“label-position”: false,
“member-access”: true,
“no-arg”: false,
“no-console”: false,
“no-construct”: false,
“no-duplicate-case”: true,
“no-duplicate-variable”: true,
“no-eval”: false,
“no-function-expression”: true,
“no-internal-module”: true,
“no-shadowed-variable”: true,
“no-switch-case-fall-through”: true,
“no-unnecessary-semicolons”: true,
“no-unused-expression”: true,
“no-use-before-declare”: true,
“no-with-statement”: true,
“semicolon”: true,
“trailing-comma”: false,
“typedef”: false,
“typedef-whitespace”: false,
“use-named-parameter”: true,
“valid-typeof”: true,
“variable-name”: false,
“whitespace”: false,
“quotemark”: [“single”, “jsx-single”]
}
}
}
3. Test the result by “gulp build”
