elio
Full-blown, fully open-source server-less infrastructure for Node.js that can run anywhere, anytime and at any scale.
Architecture
Elio was built from ground up to rely on short-running processes called Nodes that handle numerous functions under the same VM. This means that optimization passes done by a VM can apply to the entire session.
Getting Started
const Elio = require('elio');
const crypto = require('crypto');
const { InMemoryPipelines } = Elio.services;
const elio = new Elio({
maxNodes: 3, // Total number of concurrent workers (should be higher than core count for redundancy)
ttl: 30000 // Maximum execution time for functions
});
// In Memory Storage
elio.use(new InMemoryPipelines());
const source = `
module.exports = async (context) => ({
result: context.name || "echo"
});
`;
const sourceSHA1 = crypto.createHash('sha1').update(source).digest("hex");
// Emitted after at least one Node is online
elio.on('ready', async () => {
await elio.deploy('myFunction', source, sourceSHA1);
const result = await elio.invoke(sourceSHA1, { name: 'test' });
console.log(result);
});
/* Output:
{
result: "test"
}
*/
Extending Elio
Features such as NPM support and signing are available as Elio services:
const Elio = require('elio');
const { Signature } = Elio.services;
const elio = new Elio();
// Requires digest to be a signature of source code signed by a key pair
elio.use(new Signature([["userA", Buffer.from(publicKey)]]));
Services
- Package (support for NPM)
- Signature (key pair signing for all deployments)
Roadmap
- Support for pipelines
- Support for A/B
- API for custom services
- Rollbacks
