Soy nuevo en mecanografiar o node.js, estoy tratando de combinar la siguiente matriz JSON Nota: No estoy seguro de si el cliente permite nuevas dependencias o complementos.
[ { parentauthscopekey: 1, childauthscopekey: 2 }, { parentauthscopekey: 12, childauthscopekey: 10 }, { parentauthscopekey: 12, childauthscopekey: 11 }, { parentauthscopekey: 13, childauthscopekey: 1 } ]A
[ { parentauthscopekey: 1, childauthscopekey: [ 2, 1 ] }, { parentauthscopekey: 12, childauthscopekey: [ 10, 11, 12 ] }, { parentauthscopekey: 13, childauthscopekey: [ 1, 13 ] } ]Intenté el siguiente código, son demasiadas líneas pero hace el trabajo, pero esperaba algo simple sin usar el alcance codificado y los valores de scopeMap
table = [ { parentauthscopekey: 1, childauthscopekey: 2 }, { parentauthscopekey: 12, childauthscopekey: 10 }, { parentauthscopekey: 12, childauthscopekey: 11 }, { parentauthscopekey: 13, childauthscopekey: 1 } ] scope=[1,12,13] scopeMap = new Set() table2 = [] scope.forEach(parentauthscopekey => { table.forEach(row =>{ if(row.parentauthscopekey == parentauthscopekey && !scopeMap.has(parentauthscopekey)) { scopeMap.add(parentauthscopekey) childauthscopekey = [] table.filter(c => c.parentauthscopekey == row.parentauthscopekey).forEach(r=>{ childauthscopekey.push(r.childauthscopekey) }) childauthscopekey.push(parentauthscopekey) table2.push({parentauthscopekey, childauthscopekey}) } }) }) console.log(table2)puedes :
array.reduce para construir la estructura esperadaarray.filter var data = [ { parentauthscopekey: 1, childauthscopekey: 2 }, { parentauthscopekey: 12, childauthscopekey: 10 }, { parentauthscopekey: 12, childauthscopekey: 11 }, { parentauthscopekey: 13, childauthscopekey: 1 } ]; var result = data.reduce((acc, current) => { if (!acc.some(one => one.parentauthscopekey === current.parentauthscopekey)) { var childs = data.filter(one => one.parentauthscopekey === current.parentauthscopekey).map(one => one.childauthscopekey); childs.push(current.parentauthscopekey); acc.push({ parentauthscopekey: current.parentauthscopekey, childauthscopekey: childs }) } return acc; }, []); console.log(result);
