Merge 2 JSON objects from 2 files using jq - merge

Question

I have two json files
1.json
{
"outputs": {
"item1": {
"name": "name1",
"email": "email1"
}
}
}
2.json
{
"outputs": {
"item2": {
"name": "name2",
"email": "email2"
}
}
}
I'm trying to merge them using jq
jq -s '{
"Items" :
{
"list" : .[] | .outputs ,
},
}' 1.json 2.json
and I get just two Items objects, but I want to have one Items object and all item* merged like this
{
"Items": {
"objects": {
"item1": {
"name": "name1",
"email": "email1"
},
"item2": {
"name": "name2",
"email": "email2"
}
}
}
}
I've tried .[0] * .[1] trick, but I cannot put it into object construction.
How can do this with jq?

Answer 1

Try adding the --slurped array:
jq -s '{Items: {objects: map(.outputs) | add}}' 1.json 2.json
Demo
Another approach could be using reduce with inputs and the -n flag:
jq -n 'reduce inputs.outputs as $i ({}; .Items.objects += $i)' 1.json 2.json
Demo
Output:
{
"Items": {
"objects": {
"item1": {
"name": "name1",
"email": "email1"
},
"item2": {
"name": "name2",
"email": "email2"
}
}
}
}
