Throwing plain strings (not instances of Error) gives no stack traces Open
throw 'Boom!'; // eslint-disable-line no-throw-literal
- Read upRead up
- Exclude checks
Rule: no-string-throw
Flags throwing plain strings or concatenations of strings.
Rationale
Example – Doing it right
// throwing an Error from typical function, whether sync or async
if (!productToAdd) {
throw new Error("How can I add new product when no value provided?");
}
Example – Anti Pattern
// throwing a string lacks any stack trace information and other important data properties
if (!productToAdd) {
throw ("How can I add new product when no value provided?");
}
Only Error objects contain a .stack
member equivalent to the current stack trace.
Primitives such as strings do not.
Notes
- Has Fix
Config
Not configurable.
Examples
"no-string-throw": true

Rule: quotemark
Enforces quote character for string literals.
Notes
- Has Fix
Config
Five arguments may be optionally provided:
-
"single"
enforces single quotes. -
"double"
enforces double quotes. -
"backtick"
enforces backticks. -
"jsx-single"
enforces single quotes for JSX attributes. -
"jsx-double"
enforces double quotes for JSX attributes. -
"avoid-template"
forbids single-line untagged template strings that do not contain string interpolations. Note that backticks may still be used if"avoid-escape"
is enabled and both single and double quotes are present in the string (the latter option takes precedence). -
"avoid-escape"
allows you to use the "other" quotemark in cases where escaping would normally be required. For example,[true, "double", "avoid-escape"]
would not report a failure on the string literal'Hello "World"'
.

"quotemark": true,single,avoid-escape,avoid-template
