I'm working on a project where I need to loop through multiple values and then count the number of items in a database that match those values. The results are then returned.
Here is the code I am wanting to run:
var types = config.deviceTypes
for(const type of types)
{
db.find(
{
selector:
{
type: {$eq: type.name}
}
}
)
.then(results => type.count = results.docs.length)
}
return types
Running this however returns types without having made any modifications to the count since this function is being run asynchronously. I have tried making the following modification to use await:
var types = config.deviceTypes
for(const type of types)
{
var results = await db.find(
{
selector:
{
type: {$eq: type.name}
}
}
)
type.count = results.docs.length
}
return types
However this gives the error: "SyntaxError: await is only valid in async function"
I am using PouchDB on Node 14.17.0
"SyntaxError: await is only valid in async function"
The error can be fixed by making sure you're doing this in an async function.
async function foo() {
var types = config.deviceTypes
for(const type of types)
{
var results = await db.find(
{
selector:
{
type: {$eq: type.name}
}
}
)
type.count = results.docs.length
}
return types;
}
