Everything you need to go from script to internal app

Interval is a batteries-included approach to building internal tools
within your codebase. Just write business logic to power your tools
in your backend, Interval handles the rest.

User interfaces

Nobody wants to spend time building UIs for internal tools. With
Interval, just write business logic and sprinkle in calls to I/O
methods when you need to collect input or display output.
Explore I/O methods
Because you're collecting input and displaying output right from your
Node app, there's no need for REST/GraphQL APIs to connect a frontend
and backend.
const data = await db.charges.find({ userId: user.id });
const charges = await io.select.table('Select charges', {
data,
});

Authentication

By the time your Interval code is called, users have already been
fully authenticated through email, Google, or SSO.

Refund user

Search for a user[                    ]

Logs

Use the logging API to display progress to users running your
Interval apps and to store logs for audits + reference.
Logs docs
if (charge.refunded) {
ctx.log('Skipped already refunded charge:', charge.id);
}

Notifications

Dispatch notifications directly from your Interval actions. Your
teammates can receive notifications however they want: through your
group messaging app or email.
Notifications docs
if (refundAmount > 10) {
await ctx.notify({
title: 'Refund over threshold',
message: `A charge of ${refundAmount} has been refunded.`,
});
}

Built for engineers

{

Other tools force you to learn how to work in their custom
environments and runtimes. Interval supercharges your existing
codebase.

Made for Node + TypeScript

We built Interval from the ground up specifically for Node +
TypeScript. Interval's I/O methods do the heavy lifting of parsing,
sanitizing, and type checking all user input. With Interval, your
code is safer by default.
const = await io.search('Find a user', {
placeholder: 'Search by name, email, or ID',
onSearch: async query => db.findUsers(query),
});
const user
const user: {
id: string;
email: string;
firstName: string;
lastName: string;
imageUrl: string | null;
}

Build in code

Code is the primary source of truth for Interval actions.
Configuration can be done either through the Interval dashboard or
directly in code.

Build in your codebase

Love your ORM? Interval is just a regular Node module. When you add
Interval to your existing app, you can use the same shared functions,
environment variables, and 3rd party libraries as the rest of your
app.

Run on your infra

Interval apps can be deployed wherever you deploy your app. Your code
never leaves your infra and by design, Interval can't see your code
or your secrets.
