Function sanitizeGraphQLName

Sanitizes a string to be a valid GraphQL name component, preserving original capitalization. GraphQL names must match the pattern [_A-Za-z][_0-9A-Za-z]* and cannot start with double underscore

Example

// Input: Schema name with special characters
sanitizeGraphQLName("my-schema")
// Output: "myschema"
Copy

Example

// Input: Name starting with double underscore (reserved)
sanitizeGraphQLName("__mj_User")
// Output: "mjUser"
// (Removes __ prefix and underscores)
Copy

Example

// Input: Name starting with a digit
sanitizeGraphQLName("123Orders")
// Output: "_123Orders"
// (Prepends underscore since GraphQL names can't start with digits)
Copy

Example

// Input: Preserves capitalization
sanitizeGraphQLName("MyTable_Name")
// Output: "MyTableName"
// (Removes underscores but preserves case)
Copy

Example

// Input: Empty or invalid input
sanitizeGraphQLName("")
// Output: ""

sanitizeGraphQLName("!!!###")
// Output: "_"
// (All chars removed, so prepends underscore)
Copy
