```
import * as pulumi from "@pulumi/pulumi"

const allConfig = pulumi.runtime.allConfig();
```

That’s what the Config class is implemented in terms of, so it’s coming from the same source

That said, perhaps you have identified a need for something better in the Config object to handle this kind of situation, (cc <@UB3BGTV63>)

How would I use `allConfig` to get  the list key-value pairs, or the list of keys?

`allConfig` at that point would be a string dictionary, so you can do:

```
for (const key of allConfig) {
    const value = allConfig[key];

    // do something with value
}
```

You could also filter the keys etc using the higher order functions and then map them onto a new collection depending on what you’re aiming to do

okay, that works. But it doesn't really let me get config in only a single namespace

I'd have to do further string comparison and then splitting to get the keys in a namespace

Right - something new would need to be added to `Config` to allow for that

Do you know why this is failing?
```
pulumi.runtime.allConfig().forEach((value: string, key: string) =&gt; {
  console.log(key + ": " + value);
});
```

```error: Running program '/home/tsi.lan/eshamay/git/mustang/sdp-mustang-terraform/pulumi/mustang-tas-services' failed with an unhandled exception:
    error: TSError: ⨯ Unable to compile TypeScript:
    index.ts(23,1): error TS2349: Cannot invoke an expression whose type lacks a call signature. Type 'String' has no compatible call signatures.

```

allConfig() returns an object, not an array.  So you can't use `Array#forEach` on it.

```
export declare function allConfig(): {
    [key: string]: string;
};
```

So how does one iterate over the allConfig?

I tried the `for (const key of allConfig) {` above but it fails

```
const allConfig = pulumi.runtime.allConfig();
Object.keys(allConfig).forEach(key  =&gt; {
    console.log(key + ": " + allConfig[key]);
});
```

or:
```
const allConfig = pulumi.runtime.allConfig();
for (const key in allConfig) {
    console.log(key + ": " + allConfig[key]);
}
```

Sorry, I gave the wrong specifier there, `in` rather than `of`.

You can also use :

```
Object.entries(allConfig).forEach(([key, value]) =&gt; {
console.log(`${key}: ${value}`)
})
```

at least that’s what It’d personally use haha.

you probably have to create a `tsconfig.json` and set
```
{
  "compilerOptions": {
    "target": "es2017"
  }
}
```
to let typescript know that `Object.entries` exists.
And you should use node 8 or higher.
