> Javascript struct constructor should properly initialize struct and container
> members from plain js arguments
> -------------------------------------------------------------------------------------------------------------
>
> Key: THRIFT-3122
> URL: https://issues.apache.org/jira/browse/THRIFT-3122
> Project: Thrift
> Issue Type: Improvement
> Components: JavaScript - Compiler
> Reporter: Igor Tkach
> Fix For: 0.9.3

>
> Currently constructors for struct types in generated javascript accept
> {{args}} object and initialize struct's members by simply assigning a value
> from corresponding {{args}} object property (if not undefined). If struct
> member is
> another struct it must be explicitly created with constructor and passed as
> an argument value.
> Given following definitions:
> {code}
> struct A {
> 1: string something
> }
> struct B {
> 1: A value
> }
> {code}
> this works:
> {code:javascript}
> var b1 = new B(
> {
> value: new A(
> {
> something: 'hello'
> }
> )
> }
> );
> {code}
> this doesn't:
> {code:javascript}
> var b2 = new B(
> {
> value: {
> something: 'hello'
> }
> }
> );
> {code}
> Attempt to serialize b2 will result in error because {{b2.a}} doesn't have a
> {{write}} method.
> This becomes especially problematic when deep objects are used with libraries
> like [Underscore.js|http://underscorejs.org/], [lodash|https://lodash.com/],
> [React's immutability
> helpers|https://facebook.github.io/react/docs/update.html] or
> [Immutable.js|https://github.com/facebook/immutable-js]: most operations will
> return or produce plain javascript objects without read/write methods even if
> Thrift objects were given as input. Manually converting object graphs back to
> Thrift serializable form is not workable.
