Quickstart
npm i && npm run start- gateway on localhost:4444/graphql
- remote-1 on localhost:4001/graphql
- remote-1 on localhost:4002/graphql
Reconstruction of problem
The working example (non stitched)
- go to localhost:4001/graphql and query
query {articles {title {
... on TitleOne {text}
... on TitleTwo {renamedText: text}
}}}
- resulting in the list of articles (where every article has non-null value for text):
{
"data": {
"articles": [
{
"title": {
"text": "hello world"
}
},
{
"title": {
"renamedText": 1
}
},
{
"title": {
"renamedText": 2
}
},
{
"title": {
"text": "bye"
}
}
]
}
}
The problem (stitched schema)
- go to localhost:4444/graphql (the stitched schema) and query
query {articles {title {
... on TitleOne {text}
... on TitleTwo {renamedText: text}
}}}
- which results in (list of articles where the aliased fragment has a value of
null for text):
{
"data": {
"articles": [
{
"title": {
"text": "hello world"
}
},
{
"title": {
"renamedText": null
}
},
{
"title": {
"renamedText": null
}
},
{
"title": {
"text": "bye"
}
}
]
}
}
